Chiang Mai in February

November through March is peak season for good reason – temperatures hover around 25-30°C and rain stays away. December and January get busy with European winter escapees, so book accommodations early. The cool season mornings are perfect for temple visits before the heat kicks in. March brings the burning season – farmers clear fields and the air quality plummets. Avoid if you have respiratory issues. April hits 40°C regularly and feels like breathing through a hair dryer. The rainy season (May-October) means afternoon downpours, but also fewer crowds and better hotel rates.
