Thunderstorms in the north and south, Bangkok reaches 37°C

THURSDAY, FEBRUARY 19, 2026

Heavy thunderstorms are expected across northern and southern Thailand, with Bangkok experiencing intense heat reaching up to 37°C.

  • Scattered thunderstorms are forecast for Thailand's northern region, caused by southeasterly and southwesterly winds.
  • The southern region will also experience scattered thunderstorms, with mariners warned of waves exceeding 2 meters during storms.
  • The maximum temperature in Bangkok and surrounding areas is expected to reach 36-37°C.

The Thai Meteorological Department forecast for Thursday (February 19) weather over the next 24 hours, with scattered thunderstorms expected in the northern region due to southeasterly and southwesterly winds over the upper northern areas.

A moderate high-pressure system from China will affect the northeastern region, leading to cooler mornings.

Residents in the northern region are advised to be cautious of possible thunderstorms during this period.

Meanwhile, people in the upper parts of Thailand should take care of their health due to the changing weather conditions.

In the southern region, scattered thunderstorms will occur as easterly and southeasterly winds cover the Gulf of Thailand, the southern areas, and the Andaman Sea.

Waves in the lower Gulf are expected to be moderate, reaching about 2 metres in height.

During thunderstorms, wave heights could exceed 2 metres.

Mariners in the Gulf of Thailand and the Andaman Sea should proceed with caution and avoid sailing during thunderstorms.

In terms of air quality, there will be moderate dust and smoke accumulation in the northern, central, and eastern regions, including Bangkok and its surrounding areas.

This is due to weak air ventilation.
