On 10 November 2026,the Meteorological Department's websiteissued the 4th announcement regarding heavy to very heavy rain in the South (effective from 10-13 November 2026).
From 10–13 November 2026, the South will experience heavy to very heavy rain in some areas. People are advised to be cautious of continuous heavy rainfall, which may cause flash floods and mountain runoff, especially in foothill areas near waterways and lowlands. Waves in the Andaman Sea and Gulf of Thailand in thunderstorm areas will exceed 2 meters. Mariners in these waters should navigate carefully and avoid sailing in stormy areas.
Upper Thailand will have less rain but cooler weather with strong winds. The upper North will experience thunderstorms and gusty winds in some locations due to a high-pressure cold air mass extending from China covering Thailand. The public should take care of their health due to the cooler weather, and farmers should protect their crops from possible damage.
This is because a fairly strong cold air mass from China extends over upper Thailand and the South China Sea, combined with westerly wind waves moving through Myanmar and northern Thailand, while a moderate northeast monsoon covers the Gulf of Thailand, the South, and the Andaman Sea.
For safety and to minimize potential impacts, the public is advised to plan their activities and travel with caution during this period. People should follow announcements from the Meteorological Department continuously and can access information at https://tmd.go.th or call 0-2399-4012-13 and 1182, available 24 hours.
Daily weather forecast: Generally, the South will have heavy rain in some areas. People in the South should be cautious of thunderstorms, heavy rain, and accumulated rainfall, which may cause flash floods and mountain runoff, especially in foothill areas near waterways and lowlands.
Upper Thailand will have less rain and cooler weather with strong winds. The upper North will have thunderstorms and gusty winds in some areas. People in upper Thailand should take care of their health due to the cooler weather, and farmers should prepare to prevent damage to crops caused by strong winds.
This is due to another fairly strong cold air mass from China covering upper Thailand and the South China Sea, combined with westerly wind waves moving through Myanmar and northern Thailand, while a moderate northeast monsoon covers the Gulf of Thailand, the South, and the Andaman Sea.
Waves in the Andaman Sea and Gulf of Thailand are intensifying. The lower Gulf of Thailand has waves around 2 meters high; in thunderstorm areas, waves exceed 2 meters. Mariners should navigate cautiously and avoid sailing in stormy areas.
