9 November 2026 GMT+7Meteorological DepartmentBulletin No. 3 regarding Heavy to very heavy rain in southern Thailand (effective 9-13 November 2026).
From 9 to 13 November 2026, southern Thailand will experience ongoing rain with heavy rainfall in many areas and very heavy rain in some places. Residents are urged to be cautious of continuous rain accumulation that may cause flash floods and flash floods, especially in foothill areas near watercourses and low-lying regions. Sea waves in the Andaman Sea and Gulf of Thailand where thunderstorms occur will exceed 2 meters high. Mariners in these waters should navigate carefully and avoid sailing in thunderstorm areas.
In upper Thailand, the weather will cool with strong winds. In the North and Northeast, temperatures will drop by 3-5 degrees Celsius, while in the Central region, Bangkok and vicinity, and the East, temperatures will fall by 1-3 degrees Celsius due to a high-pressure system or cold air mass spreading from China. People should take care of their health amid the colder weather, and farmers should protect their crops from potential damage.
The strong high-pressure system or cold air mass from China will cover upper Thailand and the South China Sea, strengthening the northeast monsoon that affects Thailand and the Gulf of Thailand.
For safety and to minimize possible impacts, residents are advised to plan their activities and travel with caution during this period.
