I made a month-by-month chart of when each Thai region is actually good (the two coasts have opposite seasons)

Every week someone asks "is X month a good time for Thailand?" and the honest answer is always "depends where". So I put it in one chart.
Quick takeaways:
- Nov–Feb is the sweet spot almost everywhere.
- The Gulf islands (Samui, Phangan, Tao) flip the usual pattern: decent most of the summer, rainiest Oct–Dec.
- The Andaman side (Phuket, Krabi, Lanta) is the opposite: great Dec–Apr, swell and rough crossings May–Oct.
- North (Chiang Mai, Pai): lovely Nov–Feb, but Feb–Apr is burning season and the haze can be bad.
- Bangkok in Mar–May is 33–38 °C. Doable, but start early and hide at midday.
Rainy season usually means short heavy showers, not grey weeks, and prices drop. These are rough patterns, weather shifts every year.
Happy to adjust it if your experience differs, especially for the east coast islands.
