Answer
The agricultural burning season, which usually peaks from February to April, can significantly affect air quality in Chiang Mai, leading to hazy conditions and increased pollution levels.
• If you're planning to visit during this time, it's wise to keep an eye on air quality indexes and be prepared for potentially uncomfortable breathing conditions, especially for those with respiratory issues.
• Wearing a mask when going outdoors can help, and it's advisable to schedule more indoor activities during peak haze days. Many cafes and coworking spaces offer good air filtration systems.
• That said, the vibrant local culture and festivals like Songkran occur during this season, so you might consider mixing outdoor experiences with indoor ones to enjoy the best of both worlds.
Practical Chiang Mai planning note: Expect wet streets, crowds and temporary traffic changes during Songkran. Protect electronics, use clean water, respect people who do not wish to participate and check the current programme for cultural processions and ceremonies.
