Chiang Rai in March
Great time to visit
The tail end of the good weather window. Still very doable but you'll notice the heat building. Smart travelers come early March before it gets brutal.
Weather
Heat starts building as cool season winds down. Mornings are pleasantly warm around 18°C but afternoons can hit 33°C. Humidity begins its climb and occasional pre-hot season showers appear.

All Months
November through March offers perfect weather—cool mornings, warm afternoons, zero rain. December and January nights can drop to 10°C, so pack layers. This is peak season, meaning higher prices and crowds at major temples. But here's the thing: Chiang Rai never gets as crowded as other Thai destinations. Even in peak season, you can find quiet moments. April and May are brutally hot—40°C is normal—but you'll have temples almost to yourself. The rainy season from June to October brings daily afternoon showers, but mornings stay clear. Plus, the countryside turns impossibly green. Hotel rates drop by 40% during rainy season, and you'll see a different side of the Golden Triangle when rivers run high.
