On 9 Nov 2026, the Meteorological Department's website issued its 2nd announcement regarding heavy to very heavy rainfall in the southern region, effective from 9 to 13 Nov 2026.
From 9 to 13 Nov 2026, the South will continue to experience ongoing rain with heavy rain in many areas, including some places with very heavy rainfall. The public is advised to be cautious of dangers from continuous rain accumulation, which may cause flash floods and flash floods especially in foothill areas near waterways and lowlands. Waves and winds in the Andaman Sea and Gulf of Thailand will be strong, with wave heights exceeding 2 meters in areas with thunderstorms. Mariners in the Gulf of Thailand and Andaman Sea should navigate carefully and avoid sailing in areas with thunderstorms.
Upper Thailand will experience cooler weather with strong winds. The Northeast will see temperatures drop by 3-5°C, while the North, Central, Bangkok, the metropolitan area, and Eastern regions will have temperatures decrease by 1-3°C due to a strong high-pressure system or cold air mass from China spreading over Thailand. People are advised to take care of their health due to the colder weather, and farmers should prepare to protect their crops from possible damage.
This is because a strong high-pressure system or cold air mass from China is spreading over upper Thailand and the South China Sea, causing the easterly winds that blow over Thailand and the Gulf of Thailand to strengthen.
For safety and to minimize possible impacts, the public is advised to plan their activities and travel with caution during this period. People should continuously monitor announcements from the Meteorological Department and can access information at https://www.tmd.go.th or call 0-2399-4012-13 and 1182, available 24 hours.
Daily weather forecast: Generally, the South will see increasing rain with heavy to very heavy rainfall in some areas. Upper Thailand will experience decreasing rain but thunderstorms may still occur in some areas, mainly in the western parts of the North and Central regions. Temperatures will then drop with strong winds, beginning in the Northeast.
Residents in these areas should beware of dangers from thunderstorms, heavy to very heavy rain, and accumulated rainfall that may cause flash floods and flash floods, especially in foothill areas near waterways and lowlands. This is due to another strong high-pressure system or cold air mass from China spreading over upper Thailand and the South China Sea, causing easterly winds over the Gulf of Thailand, the South, and the Andaman Sea to strengthen.
Winds and waves in the Andaman Sea and Gulf of Thailand are strengthening, with waves around 2 meters high in the lower Gulf of Thailand. In areas with thunderstorms, waves may exceed 2 meters. Mariners are advised to navigate carefully and avoid sailing in areas with thunderstorms.
