Thailand’s summer season officially began on February 22, 2026, according to the Thai Meteorological Department. This year, temperatures are expected to be slightly higher than last year’s average.

In the northern and upper regions of Thailand, average maximum temperatures are forecast to reach around 36–37°C. In some high-risk areas, temperatures may climb to 42–43°C during peak periods. Provinces to watch closely include Mae Hong Son, Lampang, and Tak.

The hottest period is expected from late March to mid-April, which coincides with increased travel, tourism activity, and higher electricity consumption.

Rising temperatures each year are not just about discomfort — they also affect public health, outdoor work productivity, and household energy costs. Preparing in advance, staying hydrated, and managing energy use wisely will be essential during this year’s hot season.
