Phuket International Airport (HKT) recorded over 4.6 million passengers in Q1 2026, according to Airports of Thailand (AoT) data - a year-on-year increase of approximately 9 percent. Our analysts track these figures on a rolling basis, because passenger volume is the single strongest leading indicator for the island's short-term rental market. The lag between an arrivals surge and a measurable uplift in villa and apartment occupancy runs, based on our estimates, to 4-8 weeks, which gives investors a practical forward-looking window.
The mechanism is straightforward: as inbound traffic climbs, booking platforms register tighter availability in tourist-facing districts such as Bang Tao, Kamala, Surin, and Karon, and daily rates adjust upward. In our quarterly datasets, a 10 percent rise in arrivals has historically correlated with a 6-8 percent increase in peak-season nightly rates.
Koh Samui (USM) presents a different dynamic. AoT data for Q1 2026 shows approximately 0.52 million passengers, up roughly 5 percent year-on-year. The single-operator structure at Samui Airport caps traffic growth, but simultaneously insulates districts such as Bophut and Maenam from sudden supply-side shocks that tend to compress yields in higher-volume markets.
Quick answer
- 4.6 million passengers handled at Phuket (HKT) in Q1 2026, up approximately 9 percent year-on-year per AoT data
- 0.52 million passengers at Koh Samui (USM) in Q1 2026, up approximately 5 percent year-on-year
- Based on our estimates, the lag between an arrivals increase and a rental occupancy response is 4-8 weeks at HKT and 4-6 weeks at USM
- Short-term rental rates in Bang Tao and Kamala rose 7-12 percent year-on-year during the 2025/2026 high season (November-March)
- European travellers account for approximately 22 percent of HKT traffic as of Q1 2026
- The new condominium pipeline within 5 km of Bang Tao and Layan beaches stands at approximately 2,800 units scheduled for handover in 2026-2027, per our estimates
Options and scenarios
Base case: continued growth momentum
Our base assumption is that arrivals growth holds at 7-10 percent year-on-year through the full calendar year 2026. Under this scenario, HKT would handle approximately 18-19 million passengers for the year. Occupancy in premium districts - Surin, Layan, Bang Tao - should remain above 70 percent during the high season. Nightly rates for pool villas with 2-3 bedrooms in those locations are expected to stay in the 8,000-15,000 THB per night range, which at the Q1 2026 exchange rate environment translates to meaningful gross yields for international buyers holding baht-denominated assets.
Optimistic case: accelerating Asian traffic
China and India combined account for approximately 35 percent of HKT passenger volume. If the post-pandemic Chinese tourism recovery accelerates beyond Q4 2025 levels (which showed Chinese arrivals up 18 percent year-on-year), annual throughput could exceed 20 million passengers. In this scenario, occupancy pressure intensifies in districts popular with Asian leisure travellers - Patong, Karon, Kata - and nightly rates in those micro-markets may rise an additional 5-8 percent above the base case. Higher gross yields would follow, but so would increased competition for prime inventory.
Downside case: slowdown and stabilisation
The primary downside risk is a deceleration in global outbound travel, whether driven by macroeconomic softening or tighter visa policies. If arrivals growth slows to 2-3 percent year-on-year, annual volume would plateau near 17 million passengers. In our models, that scenario produces a 5-10 percentage-point decline in rental occupancy specifically in sub-markets facing the heaviest new supply - Bang Tao and Cherng Talay. Luxury enclaves with constrained land supply, particularly Layan and Surin, demonstrate greater resilience in this scenario.

Risks and mistakes
Over-reliance on a single indicator. Passenger volume is a strong signal, but passenger composition matters equally. Package tourists generate materially lower private rental revenue than independent travellers. In our analysis we disaggregate traffic by origin market before drawing yield conclusions.
Ignoring the supply pipeline. The Bang Tao and Cherng Talay corridor has roughly 2,800 new condominium units under construction with 2026-2027 handover targets. If demand growth does not outpace supply absorption, nightly rates in that micro-market may stabilise or dip. We verify construction progress and off-plan sales velocity on the ground. Based on our estimates, approximately 45 percent of units in this pipeline were sold off-plan as of Q1 2026, which reduces but does not eliminate the oversupply risk.
Currency exposure. The Thai baht fluctuated in a range equivalent to mild volatility against major currencies in Q1 2026. A baht appreciation of 5 percent raises the effective acquisition cost for foreign buyers while simultaneously increasing the home-currency value of rental income. We monitor the correlation between exchange-rate movements and foreign buyer decision timelines.
Extrapolating high-season data across the full year. Rental occupancy in Phuket's tourist districts falls to 35-50 percent during the low season (May-October). Yield projections built exclusively on high-season figures overstate annualised returns by 30-40 percent in our back-testing. Any credible feasibility model must account for the full seasonal cycle.
Short-term rental regulation. Thailand's Hotel Act requires a licence for any property offering stays shorter than 30 days. A number of developers market management structures designed to navigate these requirements, but regulatory risk remains real and should be assessed independently before committing to a short-term rental strategy.
FAQ
How many passengers did Phuket Airport handle in 2026?
According to AoT data, HKT processed approximately 4.6 million passengers in Q1 2026 alone. If the current 7-10 percent year-on-year growth rate is maintained, our analysts project full-year volume in the range of 18-19 million passengers.
How do Phuket arrivals data translate into rental market moves?
Based on our quarterly datasets, there is a 4-8 week lag between a measurable rise in passenger arrivals and a corresponding response in rental rates and occupancy. Historically, each 10 percent increase in arrivals has been associated with a 6-8 percent increase in peak-season nightly rates, most visibly in Bang Tao, Kamala, and Surin.
Is Koh Samui also seeing passenger growth in 2026?
Yes, though at a more moderate pace. USM recorded approximately 0.52 million passengers in Q1 2026, up around 5 percent year-on-year. The single-operator airport structure limits how fast traffic can scale, which also means Bophut and Maenam rental markets face less acute supply pressure than comparable Phuket districts.
What is the new condominium pipeline for Phuket in 2026-2027?
Per our estimates, approximately 2,800 new condominium units are scheduled for handover in the Bang Tao, Layan, and Cherng Talay corridor between 2026 and 2027. Around 45 percent of that pipeline was already sold off-plan as of Q1 2026, which provides some buffer against acute oversupply, but investors should monitor absorption rates closely.
Which Phuket districts record the highest rental occupancy?
Our data consistently shows the strongest occupancy in west-coast districts: Bang Tao, Surin, Layan, and Kamala, where high-season figures run 68-78 percent. Southern districts such as Rawai and Nai Harn post slightly lower occupancy (60-70 percent) but carry a smaller new-supply overhang, which can support more stable rate dynamics over time.
Is the Phuket low season viable for rental income?
Occupancy drops to 35-50 percent during the monsoon period (May-October). We are tracking a gradual extension of the viable rental season, driven by growing inbound flows from China, India, and South Korea. Asian leisure travel is meaningfully less seasonally concentrated than European demand, which is beginning to smooth annual revenue curves for well-positioned properties.
What are the main risks of using arrivals data to forecast rental yields?
The primary risks are passenger-mix distortion (package tourists spend less on private rentals), supply-side surprises from the new condominium pipeline, and low-season occupancy collapses that inflate annualised yield estimates if only peak-season data are used. We recommend stress-testing any yield model against the downside scenario outlined above.
Are there direct flights to Phuket from Western markets in 2026?
As of Q1 2026, no regular non-stop services operate between Western Europe or North America and Phuket. The most common routings connect via Doha (Qatar Airways hub), Dubai (Emirates hub), and Istanbul (Turkish Airlines hub), with total journey times of roughly 12-16 hours depending on connection time.
