★ February 31/16 1d Late cool-dry season, warming up. Days around 31°C, still-cool nights (16°C). Light clothing with a thin layer for the evening. From late February, agricultural burning can begin to haze the air — sensitive travelers may want a mask. High
★ March 34/18 2d Hot season + peak burning-season haze. Hot days (34°C), warm nights (18°C). Light, breathable clothing and strong sun protection. A mask is genuinely useful — air quality is often poor this month. Stay hydrated. Low
April 36/22 5d Hottest month + lingering haze early on. Very hot (36°C), warm nights (22°C). Light, breathable clothing, strong sun protection, and lots of water. Songkran (mid-April) means you will get soaked — waterproof your phone and bag. Mid
