Answer
The best time to visit Chiang Mai is from November to February when the weather is cooler, with daytime temperatures around 20°C to 25°C (68°F to 77°F). This period is ideal for outdoor activities and includes vibrant festivals such as Yi Peng and Loy Krathong, where thousands of lanterns illuminate the skies. March to June tends to be hot, particularly in April, while the rainy season lasts from May to October, with the heaviest rain typically in August and September. For enjoyable weather and exciting festivals, plan your visit during the cooler months from November to February.
Practical Chiang Mai planning note: Lantern releases are subject to current safety, aviation and event rules. Use authorised events and follow local instructions; do not assume visitors may release lanterns anywhere in the city.
