General weather conditions: 14 November 2026

The 24-hour forecast indicates that southern Thailand will continue to have heavy rain in some areas due to a moderate northeast monsoon covering the Gulf of Thailand and the south. Residents in the south should beware of heavy to very heavy rain and accumulated rainfall that may cause flash floods and forest runoff, especially in foothill areas near waterways and lowlands. The wind in the lower Gulf of Thailand is moderate with waves about 2 meters high; in thunderstorm areas, waves may exceed 2 meters. Mariners in the Gulf of Thailand and Andaman Sea should check routes and navigate with caution.

In upper Thailand, temperatures are rising with some rain in parts, but cool weather and some morning fog remain in the northern and northeastern regions. This is due to a moderate high-pressure system or cool air mass covering the north, northeast, and South China Sea, while easterly and southeasterly winds bring moisture over the lower northeast, east, and lower central regions. Residents in upper Thailand are advised to take care of their health due to changing weather, and farmers should prepare to protect crops from potential damage.

From 18 to 22 November 2026, southern Thailand will experience continuous heavy rain in many areas, with some places seeing very heavy rainfall. Residents should be cautious of accumulated rainfall causing flash floods and forest runoff, especially in foothill areas near waterways and lowlands. Winds and waves in the Gulf of Thailand and Andaman Sea will strengthen, with waves about 2 meters high in the lower Gulf and over 3 meters in thunderstorm areas. Mariners should carefully check routes and avoid sailing in thunderstorm zones.

In upper Thailand, initial thunderstorms with some strong gusts are expected, followed by colder weather with strong winds. Residents are advised to take care of their health due to changing conditions, and farmers should protect crops from possible damage.
