The Meteorological Department reports that summer storms are expected today across northern Thailand the northeastern and eastern regions due to a strong high-pressure system from China. These storms may bring thunderstorms, lightning, strong winds, and isolated hail.
The North Northeastern and eastern Thailand should prepare for summer storms, including thunder, lightning, strong gusts, and occasional hail. Other regions may experience these effects soon after.
The upper part of the country remains generally hot, with some areas in the north and central regions experiencing extremely high temperatures.
Residents in upper Thailand are advised to stay cautious. Avoid outdoor areas during storms, including open spaces, under large trees, or near unstable structures and billboards.
Advice for Farmers
Farmers should secure fruit trees and take steps to protect crops and livestock from potential damage. As the weather shifts, it’s also important to look after your health.
These weather changes are linked to moderate high-pressure zones over northern Laos and Vietnam, which are moving into northeastern Thailand and the South China Sea.

Summer Storms in Northern Thailand
Summer storms in Northern Thailand from March through May bring quick, intense downpours that often cool the sweltering heat. These storms typically roll in during the afternoons, accompanied by thunder, lightning, and strong winds.
While they’re unpredictable, they don’t last long, making it easier to plan outdoor activities around them. Farmers in the region welcome the rain as it helps water crops before the rainy season officially starts.
For travellers, it’s a good idea to carry a lightweight rain jacket or umbrella to stay dry during these short but powerful bursts of rain.
