Thailand is bracing for an exceptionally hot summer, with temperatures expected to soar to 43°C between March and April 2025.
According to The Nation Thailand, the Thailand Meteorological Department has officially declared the onset of the summer season at the end of February, forecasting high temperatures lasting until May.
This period is characterized by hot southerly winds covering the upper part of the country.
During this period, most of Thailand will experience hot and humid weather as southerly winds bring moisture from the Gulf of Thailand.
The department predicts highs of 43 degrees Celsius in some provinces during the hottest period.
However, scattered summer storms, thundershowers, gusty winds, and hail are expected to provide some relief in April and May.
The southern regions are also expected to face thunderstorms, with rainfall forecasted to increase from mid-May, particularly on the west coast, where the southwest monsoon will generate waves of 2-3 meters in the Andaman Sea.
Waves in the Gulf are forecast at 1-2 meters during this period.
Authorities are urging the public to be cautious of fire hazards and forest fires during the summer.
From late March to mid-April, extreme heat will persist for several days, during which people—especially children, seniors, and those with health conditions—should avoid prolonged outdoor exposure.
This extreme heat is expected to have significant impacts on health, agriculture, and daily life across the country. Residents and visitors are advised to stay hydrated, wear appropriate clothing, and limit outdoor activities during the hottest parts of the day.
