Answer
Climate change is increasingly affecting weather patterns in Chiang Mai, leading to unpredictable shifts in temperature and rainfall.
• For instance, the rainy season may experience heavier downpours and longer rainy spells, while the dry season could see intensified heat.
• This variability can impact travel plans, so it's wise to stay updated on forecasts and be prepared for sudden changes.
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.
