Chiang Mai weather & retreat seasons
Cool and sunny, hot and hazy, or green and rainy — what to expect, and when we are open.
Cool season
November – February
Dry, sunny days and cool, quiet mornings. In the mountains, early mornings and nights can get cold in December–February, so bring warm clothes. A wonderful time for practice.
Hot season
March – May
The hottest months. Across northern Thailand, March and April can also bring hazy air from seasonal agricultural burning. Afternoons are for resting in the shade.
Green season
June – October
The rainy season. Short, heavy showers and everything lush and green. Fewer travellers, fresh air and dramatic skies.
When is True Nature open? Our 2026–27 retreat season runs from 8 October 2026 to 1 March 2027. Outside the season we run our 200-hour teacher trainings — in 2027, 1–26 June and 1–26 September. Choose your dates to see live availability.
