The Meteorological Department has issued its final announcement warning that Southern Thailand continues to experience heavy to very heavy rainfall, especially in Prachuap Khiri Khan, Chumphon, and Surat Thani provinces, while northern Thailand sees rising temperatures with some rain in certain areas.
On 13 Nov 2026, the websiteof the Meteorological Departmentissued its final announcement, number 10, regarding heavy to very heavy rain in the southern region.
It stated that on 13 Nov 2026, Southern Thailand will continue to have heavy to very heavy rain in some locations, particularly in Prachuap Khiri Khan, Chumphon, and Surat Thani provinces. The public is advised to be cautious of dangers from continuous heavy rainfall that could cause flash floods and mountain runoff, especially in foothill areas near waterways and lowlands. Meanwhile, winds and waves in the lower Gulf of Thailand are weakening to moderate strength, with waves about 2 meters high. Areas with thunderstorms may have waves higher than 2 meters. Fishermen in the Gulf of Thailand and Andaman Sea should check their routes and navigate carefully, avoiding areas with thunderstorms.
In upper Thailand, temperatures are rising with some rainfall in certain areas, but mornings remain cool with some fog in the north and northeast. People should take care of their health due to changing weather conditions, and farmers should protect their crops from possible damage.
This is due to a relatively strong high-pressure system or cold air mass covering upper Thailand and the South China Sea weakening, while the northeast monsoon is blowing moderately over the Gulf of Thailand and southern regions.
For safety and to minimize potential impacts, the public is advised to plan their activities and travel during this period carefully. They should continuously monitor announcements from the Meteorological Department and can access information via its website.https://tmd.go.thor by calling 0-2399-4012-13 and hotline 1182 available 24 hours.
