November to February: This is the best time for Chiang Mai holidays, with cool, dry weather and temperatures topping out at 21°C to 24°C, making it perfect for exploring the outdoors, although it can get cold at night. The city is alive with festivals, including the famous Loy Krathong (Yipeng), where lanterns light up the night sky.
March to May: This period brings hot, dry weather, with average highs of 21°C to 24°C, but sometimes soaring up to 35°C. If you can handle the heat, you’ll find fewer crowds and it’s a great time for budget travellers. Be aware, though, that March and April can be smokey in some places due to the agricultural burning season, which may affect air quality.
June to October: These are the rainy months, characterised by frequent showers and lush, green scenery. The temperature generally stays around 25°C to 28°C, and though the rains can be heavy, they often clear up quickly. This season is less crowded, with hotel deals to be found, but you will need an umbrella or a waterproof jacket.
