Answer
Humidity plays a significant role in the weather here, especially during the rainy season. When humidity levels are high, it can feel much warmer than the actual temperature, leading to a sticky and uncomfortable atmosphere.
• Conversely, lower humidity can make hot days feel more bearable. It's important to keep an eye on humidity forecasts, as they can influence your plans for outdoor activities. Staying hydrated is crucial, as high humidity can lead to faster dehydration.
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.
