Answer
The rainy season in Chiang Mai runs from June to October, with the heaviest rains usually falling in August and September.
• You can expect afternoon downpours, but mornings are often sunny and pleasant, so planning outdoor activities earlier in the day can be a good strategy.
• While the rain can be intense, it also cools the air and rejuvenates the lush landscapes, making it a beautiful time to explore the countryside.
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.
