Thailand Weather Update: Cooling Temperatures and Heavy Rain Warnings
The Thai Meteorological Department has issued warnings for heavy rain in the south and cooling temperatures across the upper regions due to a new cold front.
According to a report from Khaosod Online on November 9, 2026, the Thai Meteorological Department has issued a weather alert for the next 24 hours. A relatively strong high-pressure system from China is moving over upper Thailand, leading to cooler temperatures, stronger winds, and a decrease in rainfall in those areas. Residents and farmers in the north are advised to prepare for these changing conditions.
Conversely, the southern region is facing significant weather risks. The department has identified 15 provinces in the south where heavy rainfall is expected to cover approximately 70% of the area. Authorities have warned residents in these locations to remain vigilant against potential flash floods and forest runoff, particularly in low-lying areas and near mountain slopes.
For those traveling or residing in coastal areas, maritime conditions are also shifting. The northeast monsoon is strengthening, causing waves in the lower Gulf of Thailand to reach heights of approximately two meters. In areas experiencing thunderstorms, wave heights may exceed two meters. Mariners are urged to exercise extreme caution and avoid navigating through storm-affected zones. While the cooling trend is expected to continue in the north, the duration and intensity of the southern rainfall remain subject to ongoing monitoring by meteorological officials.
