Chiang Mai in March

The smokiest month. Burning activity peaks in March, and some guides call it the worst month to visit Chiang Mai. You need an air quality app and a mask, and if you want to avoid it, November to January is the better window.

Highs averaged 35°C and lows fell only to 20°C, so evenings brought some relief. A 15°C gap between afternoon and night meant dressing twice: once for the day, once for after dark. Rain fell on only 2 days on average. March could skip rain entirely: 6 of 20 years had none, while 2022 had 6 rain days.

30 days past 30°C made it a month for early starts and a long lunch indoors. The warmest year was 2020, with highs averaging 37.5°C, 2.1°C above normal.

Typhoons i No tropical storm passed within 300 km in this month over the last 20 years. Typhoons: May
