What are the best times to visit Chiang Mai to avoid poor air quality?

• The best times to visit are typically from November to January, when air quality is generally better.

• Avoid visiting during the haze season, which usually peaks from February to April.

• Check local air quality forecasts before planning your trip for the most up-to-date information.

• Consider visiting during the rainy season from May to October, when air quality often improves.

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.
