What is the best and most cost-effective month to travel to Chiang Mai?

In terms of climate, except the rainy season from June to September every year, the rest of the time is the tourist season in Chiang Mai. Chiang Mai is located in the mountainous area of northern Thailand, surrounded by mountains, and its climate is much cooler than that of south-central Thailand. It is a summer resort in Thailand and even Southeast Asia, with an average temperature of around 20. However, the temperature difference in Chiang Mai is not big all year round, so it is very comfortable for tourists in temperate and cold zones at any time. However, June to September is the rainy season in Chiang Mai every year. There are often days of heavy rain, even flash floods, and roads are blocked. In the meantime, you should pay special attention to the weather forecast and take the necessary rain gear with you. From the perspective of tourism costs, if we don't catch up with the peak period of domestic tourism, such as May Day, National Day, winter and summer vacations, the tourism price in Chiang Mai will not be too high. The cheapest way to play is to join a group. The route of Zhongxin Travel 5000-6000 can be very good. There are many places to visit, including some shopping spots, but they are definitely not light consumption, and the shopping spots are all formal!
