Thailand’s North and Northeast see 11°C lows as southern rains ease

TUESDAY, DECEMBER 02, 2025

Thailand’s North and Northeast remain under a cold spell with minimum temperatures of 11°C, while Bangkok wakes to cool weather and light morning fog. Rain continues to ease across the South.

The Meteorological Department forecast for December 2, 2025, warns that the North and Northeast will continue to experience cold to very cold conditions, with minimum temperatures dropping to 11°C.

Bangkok and its vicinity will see cool weather with light morning fog, while rainfall across the South is expected to decrease.

Over the next 24 hours, temperatures in upper Thailand will rise slightly, and morning fog is expected, though the weather will remain cool to cold.

 

The public is advised to take care of their health due to fluctuating temperatures and to be cautious of potential fire hazards caused by dry conditions. The weakening high-pressure system over upper Thailand and the South China Sea is contributing to these changes.

In the South, rainfall is easing as the northeast monsoon over the Gulf of Thailand, the South and the Andaman Sea has weakened.

Waves in both seas are around one metre high, rising above one metre in thundery areas. Mariners are urged to navigate with caution and avoid sailing in stormy zones.

Air quality in upper Thailand is expected to worsen, with moderate to high accumulation of PM2.5 dust due to weakened winds.
