Thailand Weather Alert: Temperature Drop and Heavy Rain Warning
The Thai Meteorological Department has issued warnings for cooler temperatures in the north and heavy rainfall in the south, effective November 11, 2026.
On November 11, 2026, the Thai Meteorological Department reported that a strong high-pressure system from China is moving across upper Thailand, leading to cooler temperatures and strong winds. Residents and farmers in the north are advised to monitor their health and protect agricultural yields from wind damage. Meanwhile, the upper north may experience isolated thunderstorms and gusty winds.
For the southern region, the department has issued a severe weather warning for nine provinces, citing heavy rainfall that could trigger flash floods and forest runoff, particularly in low-lying areas and near mountain slopes. The northeast monsoon is intensifying, causing rough seas in the Gulf of Thailand and the Andaman Sea. Waves in the lower Gulf of Thailand are expected to reach heights of 2 to 3 meters, with potential for waves exceeding 3 meters in areas affected by thunderstorms.
Travelers and residents in the south should exercise extreme caution. Small boats in the lower Gulf of Thailand are advised to remain ashore during this period. While the forecast provides a clear outlook for the next 24 hours, those planning travel to coastal areas or mountainous regions should monitor local updates for potential changes in weather conditions or official warnings regarding flood risks.
