Thailand has welcomed 17.36 million international visitors through July 18, 2026, according to data released by the Tourism Authority of Thailand (TAT). The figures put the country well on track toward its annual target, with the summer holiday season accelerating arrivals from both China and key European source markets.

Summer Holiday Demand Drives Growth

The July surge reflects a broader pattern of demand that has built steadily since the start of the year. School holidays across Europe and the resumption of Chinese summer travel packages have been the two primary engines of growth. Chinese visitor numbers have rebounded strongly following a sluggish 2024, with direct charter programmes from Chengdu, Shanghai, and Shenzhen all adding capacity through July.

European arrivals — particularly from the United Kingdom, Germany, and France — have tracked above 2025 levels, with travellers extending stays beyond the typical beach resort stay into cultural itineraries that include Chiang Mai and the north.

Bangkok and Phuket Lead by Volume

Bangkok remains the entry gateway for the majority of arrivals, with Suvarnabhumi and Don Mueang airports both operating at near-capacity across the summer period. Phuket International Airport has been the beneficiary of a sharp rise in direct European charter routes, with new frequencies from Poland, the Czech Republic, and Nordic carriers adding to the established UK and German services.

Chiang Mai has seen particularly strong growth among visitors seeking an alternative to beach destinations, with trekking and elephant sanctuary visits recording consistently high booking rates through June and July.

What This Means for Visitors Right Now

Airport wait times are elevated. Suvarnabhumi’s immigration halls are operating at high capacity. Budget an additional 60–90 minutes on top of standard processing time if arriving in the evening peak (18:00–23:00).

Hotels in peak destinations are at a premium. Phuket and Koh Samui saw rates firm significantly through July. Travellers with flexible dates may find better availability in September, when monsoon activity reduces demand on the Andaman coast.

Chiang Mai offers breathing room. While Chiang Mai has seen growth, it remains far less congested than the southern beach hubs. The city’s temples, night markets, and surrounding highlands are accessible without the crush typical of peak Bangkok or Phuket periods.

Forecast for the Rest of 2026

TAT has not revised its full-year target upward despite the strong H1 performance. Officials point to the remaining monsoon months — particularly August and September on the western Andaman coast — as a natural moderating factor. The eastern Gulf coast (Koh Samui, Koh Tao, Koh Phangan) remains accessible year-round and is expected to carry demand through the low season on the opposite coast.

If the current trajectory holds, Thailand is on course to surpass 30 million arrivals for the full year — which would represent its strongest performance since before the pandemic.
