The weather in Pai
Mae Hong Son has a tropical savanna climate but is in the mountains so the morning temperatures are cooler. It is not uncommon to see the summits around the city in the mist in the morning. Winters (from November to March) are dry and warm. Temperatures rise until April, the hottest month of the year when temperatures can occasionally exceed 40 °C. The monsoon season extends from May to October, with heavy showers and cooler temperatures during the day. Mae Hong Son has the record of the highehst température ever recorded in Thailand with 44.6 °C. Surprising for a city perched in the mountains.
The best time to come to Mae Hong Son is from November to the end of April. July and August are the rainiest months but there is no time when it is particularly unrecommended to go to Mae Hong Son.
