The weather of Northern Thailand, which includes Chiang Mai, has three distinct seasons: the cool season, the hot season and the rainy season. Unlike the traditional seasonal divisions of spring, summer, autumn and winter, Chiang Mai is known to be the cool capital of Thailand in comparison to the sweaty and humid heat of Bangkok. The weather in Chiang Mai is far more pleasant than that of Bangkok.
Here is a detailed description of Chiang Mai’s monthly weather:
January – January Chiang Mai weather is the most pleasant and this is the most popular time to visit as it the country experiences its coolest weather. Chiang Mai and the mountains become a novelty for Thai tourists with similar temperatures to a sunny European summer day. It gets somewhat chilly and hazy at night.
February – Similar to January, the month of February still hae favorable temperatures though it may get quite hot during midday in the valleys. No rains should be expected as landscapes are dry and the vistas are hazy. Tourist areas and services remain rather busy.
March – Visiting Chiang Mai during the month of March is not ideal because the air is thick with dust due to the widespread rural burning. The haze over the city removes the view of the mountains, there is no breeze and the outcomes can be health hazards on some days.
April – Chiang May can get extremely hot during April as temperatures peak to the mid 30s Celsius. Rain does not occur and landscapes are dry. A popular reason to visit the region now, however, is the annual Songkran water splash festival, which is best enjoyed in the city.

September – September is deemed the quietest month for tourism in Chiang Mai mostly due to the wet weather. Showers occur daily, although with a good amount of sunshine and high humidity. The best tourist bargains occur during this month.
October – October is one of the prettiest times to visit Chiang Mai with a patchwork of green extending across the landscape. Occasional rains may still occur but the climate remains rather sunny with less humidity.
November – Tourist season starts yet again in November as the weather dries up. Expect sunny skies and cooler days with lush green landscapes and clear mountain views. It is one of the best times to visit the region where tourist attractions are not too busy.
