Weather in Chiang Mai

Best time to visit

The peak season for visiting Chiang Mai is December to January, the only time of year when daytime temperatures dip below 30°C (86°F). The cooler weather is a welcome change from the steamy monsoon months (June to October), and the lack of rain makes this the perfect time to venture out into the hills. However, many visitors plan their trip by the festival calendar, with the Chiang Mai Flower Festival in February and Inthakin in May amongst the most popular events.
