Cool Season (November to February) – Peak for Festivals and Trekking
This is the best time to visit Chiang Mai if you're looking for great weather, vibrant festivals, and outdoor fun.

The mercury rises, but so does your chance for amazing deals. If you’re heat-tolerant, this can still be the best time to visit Chiang Mai on a budget.

Rainy Season (June to October) – Green, Peaceful, and Budget-Friendly
If you're after lush scenery and lower prices, the rainy season might just be your personal best time to visit Chiang Mai.
- Weather: Humid with brief showers, mostly in late afternoon or at night. Expect fresh air, blooming rice fields, and waterfalls in full force.
- Why Go Now:
- Prices drop dramatically at hotels and tour companies
- No need to jostle with crowds—Old Town is serene and slow-paced
