Seasons in Chiang Mai

The Cool Season

During the cool season (November through early February), daytime temperatures typically range from 15-30°C (59-86°F), making it ideal for outdoor activities and exploring the city.

The Burning Season

During the “Burning” season in late February through mid April, farmers will set alight the crop residues after the last harvest. This burning leads to a lot of smoke and particulate matter that contributes to poor air quality. Travelers with asthma or allergies should be particularly cautious during this period.

The Rainy Season

In May, the rainy season begins and stretches into October, with the heaviest rainfall occurring in September and October. While temperatures tend to decrease slightly after May, the air is a lot more humid and muggy than in the winter. That being said, visiting in the rainy season can be much more affordable if you are on a shoestring budget.

Popular Festivals In Chiang Mai By Month

Chiang Mai hosts several unique festivals throughout the year, each offering a distinct cultural experience. Timing your trip around one of Chiang Mai’s many festivals can be a fantastic way to immerse yourself in the local culture. Conversely, if you’re looking to escape the crowds, consider planning your trip to avoid festivals.

November: Loy Krathong (sky lantern festival)

The famed floating sky lantern festival, Loy Krathong is a traditional Thai festival celebrated annually. The festival date is dependent on the date of the full moon which is typically around November.

January: Bo Sang Umbrella Festival

Bo Sang Umbrella & Sankampang Handicrafts Festival is a three day festival celebrated on the third weekend in January each year to highlight the craftsmanship of local artisans.

February: Chiang Mai Flower Festival

Running for over forty years, the Chiang Mai Flower Festival runs over three days at the end of February each year. It celebrates the beautiful flowers in bloom during this time of the year and attracts thousands of visitors to Chiang Mai.

April: Songkran

Celebrated all across Thailand, Songkran is the biggest water fight in the world. During this holiday, both locals and foreigners alike splash water at each other with super soakers. Originally, this holiday used water for holy cleansing, but it has since evolved into a more goofy holiday.
