Answer
The rainy season, which runs from June to October, brings frequent afternoon showers. While it can put a damper on some outdoor plans, it also means that the surrounding nature is lush and vibrant.
• If you're visiting during this time, it's wise to plan your activities for the mornings when rain is less likely. And don't forget to carry a lightweight rain jacket or an umbrella to stay dry!
• Some travellers love this season for fewer crowds and lower accommodation prices, making it a great time for those looking to explore without the hustle and bustle.
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.
