November
Cool season starts: drier, clearer and more comfortable. The Andaman coast reopens for diving. Koh Samui is at its wettest.
Thailand's three seasons
Cool season
Dry, sunny and as comfortable as Bangkok gets. Peak travel season, with prices to match. The north can be chilly at night.
Hot season
Mid-30s and humid, with April the peak. The north's burning season brings haze: watch PM2.5, especially in Chiang Mai.
Rainy season
Heavy afternoon downpours rather than all-day rain. Flash flooding in low streets, rough seas on the Andaman coast.
The Gulf exception
Koh Samui, Koh Phangan and Koh Tao get their main rains late in the year, when the rest of the country dries out.
