Chiang Mai has been known as a cool weather. It’s not too cold for the travelers, but sometimes it’s very hot and sunny on the season of summer. However, if we compare the season in Thailand, Chiang Mai is very cold, because there are places connected with the mountains.

The reality is that in the hot summer months (March till June), Chiang Mai can be just as uncomfortably hot as much of the rest of the country. The heat starts to increase soon after the New Year and by April or May it can be almost unbearably hot and humid. |

The cool season runs from December to February, although there's usually just one week in December when temperatures are actually comfortable. However, from December to February the nights can be cool enough to require a jacket, so the appellation is not totally undeserved. |

The rainy season some year is entirely bad time to visit since the rain generally falls within the span of an hour or two in the late afternoons. The rain cools down the temperatures a bit and cleans the air quite nicely. If it’s high temperatures, the rain is not too cold. It’s during on July to November. |
