Thailand’s tourism sector passed two milestones simultaneously in September 2026. The Tourism Authority of Thailand (TAT) confirmed that international arrivals crossed 21 million for the year to date, and total tourism revenue crossed the 1 trillion baht mark — both figures arriving ahead of the same point in previous years.
What the Numbers Mean
Thailand’s pre-pandemic record was roughly 40 million international arrivals in 2019. The government set a 35-million target for 2026. At 21 million by early September with the high season still ahead, TAT officials say the full-year target is within reach.
The 1 trillion baht revenue figure — approximately USD 27 billion at current exchange rates — accounts for spending by international tourists across accommodation, food, transport, and activities. It reflects both higher visitor numbers and an increase in average spend per trip compared with 2024 and 2025.
Which Markets Are Driving Growth
Malaysia, China, India, South Korea, and the United Kingdom are the five largest source markets by arrivals this year. The China recovery has been notable: Chinese arrivals are running around 40% higher than in 2025, helped by direct flight capacity added during Q1 and the easing of group tour restrictions.
Long-haul markets — including Europe and North America — are also up. Thailand’s appeal to digital nomads and remote workers has extended average length of stay among Western visitors, which partly explains the disproportionate revenue gain relative to arrivals growth.
What This Means for Travellers Planning a Trip
High season runs October through February. If you are planning a visit during this window, book accommodation and transport earlier than you normally would. Flight prices from Europe and North America are elevated on popular departure dates from late October onward.
For travellers with flexibility, shoulder-season October is still excellent value in the north — Chiang Mai, Chiang Rai, and the surrounding regions see clear weather, lower crowds at temples and trekking routes, and hotel rates that have not yet peaked.

Outlook for the Rest of 2026
TAT is forecasting an acceleration in arrivals through Q4, driven by Chinese Golden Week (1–7 October), the Indian Diwali holiday window, and European winter-sun travel. Phuket, Koh Samui, and Bangkok’s hotel markets are already reporting above-average advance bookings for November and December.
The government is also accelerating infrastructure work at Suvarnabhumi Airport ahead of peak season, including additional check-in counters and expanded immigration lanes, after congestion complaints during Songkran in April.
