Answer

The rainy season in Chiang Mai runs from June to October, with the heaviest rains usually in August and September.

• While you can expect daily showers, they often come in short bursts, leaving plenty of time for exploration in between.

• It's a great time to enjoy the lush greenery, but be prepared with waterproof gear and plan indoor activities just in case.

Practical Chiang Mai planning note: For weather and air quality, check a current forecast and a live air-quality source shortly before the activity. Northern Thailand can experience strong seasonal variation, and conditions differ between the city, foothills and higher mountains.
