Answer
It's wise to stay informed about the weather patterns, especially during the hot season from March to May, when temperatures can soar above 35°C (95°F).
• Make sure to have plenty of water on hand and wear light, breathable clothing to keep cool.
• In case of unexpected rain, having an umbrella or raincoat is a good idea, especially during the rainy season from June to October.
• Consider creating a flexible plan for your daily activities, allowing for indoor options if the weather turns unfavorable.
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.
