🇹🇭 Chiang Mai · When to go
The best time to visit Chiang Mai
Chiang Mai is best in the cool, dry season (November–February) — comfortable days, low humidity and clear skies. The hot season (March–May) is intense, and crucially the burning season (roughly mid-February–April) brings heavy smoke haze and poor air quality. The wet season (June–October) is green, quiet and cheap.

When is the best time to visit Chiang Mai?
November to February — the cool, dry season has the most comfortable weather and the cleanest air.
What is the burning season in Chiang Mai?
Roughly mid-February to April, when agricultural burning causes heavy smoke haze and unhealthy air quality — many travellers avoid this window.
When is the Yi Peng lantern festival?
November, alongside Loy Krathong — one of the most beautiful times to visit, so book well ahead.
Is the rainy season a bad time for Chiang Mai?
Not really — it’s green, quiet and cheap, with rain usually in short afternoon bursts, and far better air than the burning season.
