Thailand is forecast to enter a hotter‑than‑usual summer later this month, with peak temperatures in some northern provinces likely to climb beyond 42°C, according to the Meteorological Department.
The 2026 hot season is forecast to begin in late February, around two weeks later than normal, and end in mid‑May. Average maximum temperatures across the upper regions are expected to reach 36–37°C, slightly above both the long‑term seasonal norm of 35.4°C and last year’s average of 35.8°C.
