Answer
• Chiang Mai experiences a tropical climate with three main seasons: the cool season from November to February, the hot season from March to May, and the rainy season from June to October.
• During the cool season, temperatures are mild and pleasant, making it ideal for outdoor activities.
• The hot season can be quite warm, often exceeding 35°C, while the rainy season brings frequent showers, especially in the afternoons.
• Understanding these patterns can help you plan your visit accordingly.
Practical Chiang Mai planning note: For weather and air quality, check a current forecast and a live air-quality source shortly before the activity. Northern Thailand can experience strong seasonal variation, and conditions differ between the city, foothills and higher mountains.
