Chiang Mai in May
Not the best time
Still brutally hot but smoke clears and tourist crowds thin out significantly. The increasing rain provides some relief, though humidity makes everything feel sticky.
Weather
Sweltering heat continues around 36°C while humidity jumps as rainy season approaches. Pre-monsoon storms bring brief relief but make the air muggy. Burning season finally starts clearing.

All Months
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.
