SUMMARY
Koh Samui is becoming more Phuket-like, but it is not on track to become Phuket at the same scale. The stronger thesis is that Samui is deepening into a more international, more developed and potentially more expensive island market while remaining much smaller and more constrained.
Tourism has already moved beyond the old recovery story. Samui airport traffic rose above its pre-Covid peak, which means the island is now dealing with genuine growth rather than simply replacing lost visitors.
The most visible property shift is not just higher prices or more villas. Large condominium projects are entering a market that was historically far more villa-heavy, and two projects alone account for roughly 38% of Samui's current primary residential inventory.
That small base cuts both ways. Samui needs far fewer new projects than Phuket to create a local supply problem, so a handful of large launches can change the market surprisingly quickly.
Phuket remains in another category of scale. Its airport traffic is more than six times Samui's recent level, its registered hotel stock is roughly four times larger, and its primary residential market is around fifteen times bigger.
Samui's limited air network may turn out to be a feature as much as a constraint. It caps Phuket-style mass tourism while helping preserve a more concentrated, higher-spending leisure market.
The villa market is already becoming more competitive. Rental supply rose sharply while average nightly rates fell, even as occupancy improved, which suggests demand is strong but scarcity is weakening.
The planned cruise terminal could materially expand visitor flows, but it should not be priced into property today as guaranteed demand. The project still faces approvals, tendering and a long timetable before the planned 2032 opening.
Infrastructure may become the island's real ceiling. Water, wastewater, roads and utilities are under pressure already, so Samui could hit practical capacity limits well before tourist demand disappears.
The most interesting long-term outcome is a smaller premium island rather than a mini-Phuket. Scarce beachfront and sea-view assets could keep appreciating while ordinary villas and less differentiated projects face heavier competition.
For buyers, the useful thesis is therefore not that Samui will copy Phuket. It is that Samui is becoming a deeper international market while its physical constraints preserve scarcity in the best locations.

Is Koh Samui really becoming the next Phuket?
Koh Samui is becoming more like Phuket, but calling it “the next Phuket” still goes too far.
The comparison makes sense because several things are happening at once. Samui tourism has moved beyond its pre-Covid peak, large condominium projects have appeared in a market historically dominated by villas, international hotel groups continue to expand, and the government is pushing a THB12.17 billion cruise terminal that could eventually bring far more passengers directly onto the island.
Those changes are substantial. Samui has entered a different stage of development.
Yet Phuket has already moved several stages further. Phuket welcomed 8.8 million airport passenger arrivals in 2025 according to C9 Hotelworks. Its airport handled about 17.4 million arriving and departing passengers that year, while its hotel stock is approaching 100,000 registered rooms. C9's latest property work puts Phuket's primary residential inventory above 43,000 units.
Samui Airport handled about 2.76 million passengers in 2024, while Samui had roughly 24,000 registered hotel rooms and 2,882 primary residential units in C9's latest dedicated island studies.
So yes, Samui is moving in Phuket's direction. We see little evidence that it is actually becoming Phuket-sized.
| Measure | Koh Samui | Phuket | What it tells us |
|---|---|---|---|
| Recent airport passenger traffic | ~2.76m | ~17.4m | Phuket operates at more than 6x the aviation scale |
| Registered / projected hotel rooms | ~24,000 | ~100,000 | Phuket has roughly 4x the room stock |
| Primary residential supply | 2,882 units | >43,000 units | Phuket's development market is about 15x larger |
| Main tourism model | Resort, villa, luxury leisure | Mass, luxury, residential and urban tourism | Samui remains much more specialized |
| International access | Limited direct network | Large international gateway | Samui's growth still has a natural ceiling |
Why does Koh Samui feel so much busier now?
Koh Samui feels busier because tourism demand has grown much faster than the island itself.
C9 Hotelworks counted about 2.78 million Samui Airport passengers in 2024, 21% more than a year earlier and above the 2.42 million recorded in 2019. The increase continued into 2025, with 1.13 million arrivals during the first four months, up another 9% year on year.
Samui's recovery had clearly moved beyond a simple “back to normal after Covid” story once airport traffic moved above the old peak.
Hotel and villa data point the same way. Occupancy improved while more rental villas entered the market. The number of independent villas available for rent jumped 34% year on year in C9's early-2025 review.
The island therefore has more tourists, more rental homes and more property development moving through largely the same road network and coastal geography.
That combination explains why the change can feel faster on the ground than the headline visitor numbers suggest.
Don't buy the wrong property, in the wrong area of Koh Samui
Buying real estate is a significant investment. Don't rely solely on your intuition. Gather the right information to make the best decision.
Is Koh Samui tourism actually catching Phuket?
Koh Samui tourism is growing strongly, but Samui is nowhere close to catching Phuket in visitor scale.
Phuket recorded 8.8 million airport passenger arrivals in 2025 despite a sharp fall in Chinese visitors. Through the first five months of 2026, Airports of Thailand recorded another 3.92 million arrivals, almost exactly level with the same period in 2025.
That latest figure is useful because Phuket has recently dealt with weaker Chinese demand, disruptions to some Middle Eastern air connections and a difficult tourism environment without suffering a major collapse in overall arrivals. Its visitor base is large enough for weakness in one market to be partly replaced by another.
Samui has also been resilient, and Bangkok Airways' latest results show that the airline serving the island remains financially strong. Bangkok Airways reported THB2.43 billion of net profit for the first half of 2026, up 16.3% year on year.
Still, the scale difference remains huge. Even allowing for different ways of counting tourists and airport passengers, Phuket handles several times more travel activity than Samui.
Samui can have a major tourism boom without ever getting close to Phuket's volumes.
Are Koh Samui and Phuket attracting the same kind of tourists?
Koh Samui still attracts a noticeably more concentrated, higher-spending leisure crowd than Phuket.
European travelers accounted for 56% of Samui's international arrivals in C9 Hotelworks' latest dedicated tourism review, with Germany, the United Kingdom and France among the largest source markets. Australia was also growing quickly.
Phuket pulls demand from a much wider collection of markets. Russia, Europe, India, China, Australia, the Middle East and domestic Thailand all contribute meaningful volumes. The island also serves very different types of visitors depending on the area, from Patong's high-volume tourism to luxury resorts and expensive residences farther north.
We can see that diversification in current property demand too. FazWaz data presented through C9 in 2026 covered 54,628 Phuket property enquiries coming from 141 countries in only six months.
Samui has nowhere near that breadth yet.
That difference could actually help preserve Samui's character. The island can support expensive villas and resorts without needing anything close to Phuket's visitor numbers.
| Tourism characteristic | Koh Samui | Phuket |
|---|---|---|
| European dependence | Very high | Important, but one part of a broader mix |
| Mass tourism | Still relatively limited | Major market |
| Luxury leisure | Central to the island | Large segment within a much bigger market |
| International buyer base | Strong but narrower | Extremely broad |
| Destination structure | Mostly resort and leisure areas | Resort, residential and increasingly urban hubs |

Is Koh Samui becoming easier to reach?
Koh Samui is easier to reach than before, but its airport still puts a real brake on Phuket-style growth.
Samui Airport handled about 2.76 million passengers and 30,381 flights in 2024 according to Bangkok Airways' shareholder reporting. The airport has theoretical capacity for considerably more traffic, so Samui is not physically “full” in the simple sense.
Access is constrained in another way. Bangkok Airways remains the dominant carrier and much of Samui's international demand still reaches the island through a connection. Direct scheduled international routes remain limited compared with Phuket.
Bangkok Airways is currently selling direct Samui flights to Singapore and Hong Kong, and its wider codeshare network gives travelers many connecting options. The airline is also bringing in 12 new ATR 72-600 aircraft between 2026 and 2028.
That should support incremental growth.
Phuket works differently. Travelers can fly directly from a long list of Asian, Middle Eastern and European cities, which allows the island to absorb tourism at a completely different scale.
As long as that gap remains, Samui is unlikely to experience the same volume-led development cycle as Phuket.
Is Koh Samui's property market starting to look like Phuket?
Koh Samui's property market is starting to resemble an earlier version of Phuket more clearly than its tourism market does.
C9 Hotelworks counted 2,882 developer-owned primary residential units across 117 Samui projects, worth about THB30.3 billion. For years, the market was mainly associated with individual villas and relatively small luxury developments.
Large condominium schemes are changing that pattern.
Anava Samui has 564 units and Wing Samui has 533. Together, those two developments contain 1,097 units, equivalent to about 38% of the entire primary-market inventory counted in C9's Samui survey.
Two projects representing almost two-fifths of the existing primary supply is a big change for a market this small.
Here the Phuket comparison is more revealing. Phuket went through a similar broad transition as holiday homes and villa estates were joined by increasingly large condominium projects, branded residences and integrated developments.
Samui is only beginning that transition, but the change in development format is real.
| Residential measure | Koh Samui | Phuket |
|---|---|---|
| Primary residential supply | 2,882 units | >43,000 units |
| Samui's two large condo projects | 1,097 units | N/A |
| Two projects as share of Samui's current primary stock | ~38% | N/A |
| Traditional product | Villas | Condos + villas |
| Large-scale development | Emerging | Already normal |
Buying real estate in Koh Samui can be risky
An increasing number of foreign investors are showing interest. However, 90% of them will make mistakes. Avoid the pitfalls with our comprehensive guide.
How far behind Phuket is Koh Samui real estate?
Koh Samui real estate remains tiny next to Phuket, even after Samui's recent development boom.
C9 counted 40,600 Phuket resort-grade residential units for sale across 343 developments in early 2025. A later C9 property outlook put primary-market inventory at 43,481 units.
That later figure is roughly fifteen times Samui's 2,882-unit primary market.
Phuket is also several years deeper into institutional development. Bangkok-listed developers such as Sansiri, Origin, Supalai and others now operate on the island. Branded residences are widespread. Developers increasingly build entire residential communities rather than isolated holiday projects.
The clearest current example is Bangtao. C9's 2026 work identified nine new hotels and nine branded-residence developments scheduled between 2026 and 2030, bringing 1,640 hotel rooms and 1,649 residences to that one coastal corridor.
One part of Phuket therefore has a branded-residence pipeline larger than half of Samui's entire current primary residential market.
That is the scale difference people miss when they casually describe Samui as the next Phuket.
Is Koh Samui already building too much?
Koh Samui is starting to show supply pressure in villas, although the evidence is still too mixed to call the whole island overbuilt.
C9 found independent villa rental supply rising 34% year on year while the average nightly rate fell 11% to THB13,012 during the first quarter of 2025.
Normally, those two figures would make us nervous. But occupancy simultaneously increased by 5.7 percentage points to 71.5%.
So the extra villas were being used. Owners were simply competing harder on price.
That is more interesting than either “Samui demand is booming” or “Samui is oversupplied.” Demand grew strongly enough to absorb a large expansion in inventory, but scarcity was already weakening.
Colliers' later residential review also described continued foreign demand and expected prime villa prices to keep rising, especially for beachfront and sea-view properties. We would put less weight on the forecast itself than on the underlying split it implies: the best sites may remain scarce even while generic investment villas become much easier to find.
As Samui develops, location and product quality should matter more and the simple “buy any villa because supply is limited” argument should become weaker.
| Samui villa indicator | Recent change |
|---|---|
| Rental villa supply | +34% YoY |
| Average nightly rate | -11% YoY |
| Average nightly rate | THB13,012 |
| Occupancy | 71.5% |
| Occupancy change | +5.7 percentage points |

Could Koh Samui eventually get Phuket's condo oversupply problem?
Koh Samui could eventually build too many condominiums, but we are not there yet.
Phuket shows what the mature version of this risk looks like. Its primary residential stock has moved above 40,000 units, and developers are competing with both new launches and an expanding resale market.
Current Phuket demand is real, but it is also more price-sensitive than the luxury-island story sometimes suggests. FazWaz recorded 15,586 sales enquiries between December 2025 and May 2026, while rental enquiries reached 39,042. Rentals therefore represented 71% of all enquiries in the dataset.
There was also a striking sales spike in March, when the median buyer budget jumped from THB6 million to THB14 million. By the following month, demand had already moved back toward its previous pattern. Treating one hot month as a permanent change would have been a mistake.
Samui currently has much less inventory, but its smaller base means a few developments can move the market quickly. Another four projects the size of Anava Samui or Wing Samui would add more than 2,000 units, equivalent to roughly 70% of Samui's existing primary stock.
That is the number we would watch. Samui does not need anything close to Phuket's construction volume to create a local supply problem.
Is Koh Samui becoming a mass-tourism island?
Koh Samui is getting busier, but it still does not look like a mass-tourism island on Phuket's scale.
Samui's accommodation base remains one of the biggest differences. The island has roughly 24,000 registered hotel rooms. Phuket is moving toward 100,000.
Phuket also has places built around very high visitor throughput. Patong alone contains a density of hotels, nightlife, retail, restaurants and short-stay accommodation that Samui does not reproduce anywhere at the same scale.
Samui's dominant tourism products remain resorts, villas, beaches, wellness and higher-end leisure travel. Its airport economics also make the island relatively expensive to reach, which naturally filters part of the mass market.
Current growth could certainly make Chaweng, Bo Phut and other popular areas much denser. Large condominium developments may gradually widen the buyer and visitor base too.
But Samui can become significantly busier without turning into Patong spread around an entire island.

Will Koh Samui's new cruise terminal change the island?
Koh Samui's planned cruise terminal could bring a meaningful new wave of visitors, but investors should stop treating it as if it were already built.
The project is moving forward again. The Transport Ministry currently values it at about THB12.17 billion and plans to develop it through a public-private partnership.
The proposed terminal would handle up to 240 cruise calls and roughly 400,000 passengers a year. That would be a substantial increase from the 94,681 cruise passengers Samui received from 50 ship calls in 2024.
But the latest timetable also makes the uncertainty clear. Cabinet approval is targeted for 2027, tendering comes later, and operations are planned for 2032.
The environmental approval process has already caused delays. In 2025, the PPP Committee sent the project studies back and required a new Environmental and Health Impact Assessment.
The terminal deserves to be taken seriously because the government continues to advance it. Treating hundreds of thousands of future cruise visitors as guaranteed demand today would be much harder to justify.
| Cruise measure | Recent Samui level | Planned terminal capacity |
|---|---|---|
| Annual cruise calls | 50 in 2024 | Up to 240 |
| Annual passengers | 94,681 in 2024 | Up to 400,000 |
| Arrival method | Offshore anchoring and tenders | Dedicated deep-water terminal |
| Estimated investment | N/A | ~THB12.17bn |
| Planned operations | Existing system | 2032 |
Can Koh Samui's infrastructure actually handle much more growth?
Koh Samui's infrastructure is already becoming one of the strongest arguments against unlimited growth.
Water and wastewater are particularly telling. During a government visit to Samui, local officials said the municipality did not have enough funding for large-scale wastewater treatment and raised concerns about inadequate tap-water supply for residents and tourists. Officials discussed both additional wastewater funding and a large undersea water pipeline.
Those are basic systems, not optional improvements.
The pressure becomes more important when we put it next to what is being planned: more housing, more tourists, larger residential projects and eventually a cruise terminal capable of handling hundreds of thousands of passengers a year.
Phuket offers a useful warning because it has spent years trying to catch infrastructure up with development. Phuket International Airport handled around 17.4 million passengers in 2025 despite stated capacity around 12.5 million, while expressways, airport expansion and other transport projects are now being pushed to relieve congestion.
Samui is far smaller, but its infrastructure is smaller too.
If Samui continues to grow quickly these days, water, wastewater, roads and utilities could determine the island's practical development ceiling long before tourist demand disappears.

Could Koh Samui become more expensive than Phuket without becoming as big?
Koh Samui could become a smaller and scarcer premium market rather than trying to match Phuket's scale.
Samui's hotel supply has historically grown slowly compared with its tourism recovery. Prime beachfront and sea-view land is naturally limited. Foreign buyers remain an important part of villa demand. Colliers expects prime villa zones to appreciate around 7.5% annually through 2030, with the best beachfront and sea-view assets potentially growing faster, although those numbers are forecasts rather than observed future returns.
Phuket is dealing with different economics. C9's latest outlook puts more than 43,000 residences in its primary market and forecasts more than 102,000 registered hotel rooms by 2029.
The Bangtao pipeline makes the contrast even clearer. Between 2026 and 2030, that corridor alone is scheduled to add roughly 3,300 branded hotel and residential units alongside new retail and an international school.
Samui has fewer opportunities to create something on that scale.
That could protect genuinely scarce Samui property even if the island never comes close to Phuket's visitor numbers. It could also create a more divided market in which exceptional land keeps getting more expensive while ordinary villas face heavier competition.
Is Koh Samui's boom more fragile than Phuket's?
Koh Samui's tourism boom is more exposed to a few markets and airlines than Phuket's, which makes Samui more fragile when something goes wrong.
European travelers make up an unusually large share of Samui's international market. Bangkok Airways also plays an outsized role in getting visitors onto the island.
Phuket has enough scale and connectivity to replace demand more easily. Chinese visitor numbers fell sharply in Phuket in 2025, yet total airport arrivals still reached 8.8 million as other markets helped fill the gap.
We have seen another version of that resilience in 2026. Through May, Phuket airport arrivals were down only 0.1% year on year even though April arrivals dropped 9.1% during disruption to Gulf air connectivity. May improved to only 2% below the previous year.
Samui does not have the same cushion.
That does not make Samui a weak tourism market. It means a concentrated destination can look exceptionally strong when its main source markets are healthy and suffer more quickly when one of them turns.

So, is Koh Samui becoming the next Phuket?
Partly, but “the next Phuket” is still the wrong end point for Koh Samui.
The direction is increasingly obvious. Samui has moved beyond its old tourism peak. Large condominium projects are changing a villa-heavy residential market. International investors and hotel groups are paying more attention. The government is advancing a major cruise terminal. Infrastructure pressure is becoming harder to ignore.
Those are exactly the kinds of changes we would expect when a small resort island becomes a much more serious tourism and property market.
Phuket currently belongs to another category of scale. Its residential market is around fifteen times larger by primary inventory. Its accommodation stock is roughly four times greater. Its airport traffic is more than six times Samui's recent total. Phuket now supports large residential communities, schools, shopping centers, healthcare, branded residences and increasingly urban coastal districts that function well beyond conventional holiday tourism.
And as seen above, Samui's constrained infrastructure and narrower air network make simply copying that expansion difficult.
The better frame is that Koh Samui is going through part of the transformation Phuket went through, while its likely end state remains different.
The more plausible outcome now is a smaller, more expensive and more tourism-focused island where development keeps intensifying but physical constraints preserve some scarcity.
That distinction is important for property buyers. Buying Samui because “it will become Phuket” assumes that more development automatically produces Phuket-style liquidity, connectivity and scale. The evidence does not support that leap.
Buying Samui because it is becoming a deeper international market while remaining much smaller is a far more defensible thesis.
So yes, Koh Samui is becoming more Phuket-like. For now, though, Samui's strongest future may come from never becoming Phuket completely.
OUR METHODOLOGY
This analysis tests whether Koh Samui is genuinely moving toward a Phuket-style tourism and property model, rather than assuming the comparison is true because the island feels busier or more developed.
We break the question into the areas that most clearly show how an island market is changing: tourism scale and composition, air connectivity, accommodation capacity, residential development, supply and demand conditions, infrastructure pressure, and major future catalysts such as the planned cruise terminal.
For each area, we use the freshest relevant evidence available in the source set and match the source to the question. Government agencies, airport operators and Bangkok Airways are used for aviation and infrastructure; specialist market research is used for hotel, villa and residential supply; and current enquiry datasets are used to understand buyer and rental demand.
Observed operating data carries more weight than forecasts. Planned infrastructure is kept separate from capacity or demand that already exists, and forecasts for future price growth are treated as scenarios rather than as realized returns.
We also keep unlike measures separate. Airport arrivals are not automatically interchangeable with total airport throughput, primary residential inventory is not the same thing as the island's entire housing stock, enquiries are evidence of demand rather than completed transactions, and announced project pipelines are not existing supply.
Phuket is used as a benchmark, not as a predetermined future for Samui. The comparison is meant to show which parts of Phuket's earlier development path are now appearing in Samui, which remain far apart, and where Samui's smaller scale and physical constraints point toward a different outcome.
No single statistic determines the conclusion. We look for consistency across tourism, property, access, infrastructure and supply-demand data, then judge whether the combined evidence supports a Phuket-style expansion or a smaller premium-market outcome.
