Bangkok: Getting ready for the cold front on 26-28 January, temperatures will drop another 2-5 degrees Celsius as the weather throughout Thailand is expected to turn cooler. The Meteorological Department has reported that the mornings will remain cool, with mountaintops and hilltops experiencing very cold conditions.
According to Thai News Agency, a high-pressure area or slightly cold air mass is currently covering the upper part of Thailand and the South China Sea. This atmospheric condition contributes to morning fog and dense fog in multiple regions. The North and Northeast will experience cool to cold weather, while the Central region, including Bangkok and its vicinity, the East, and the upper South will have cool mornings. The mountaintops and hills are expected to encounter cold to very cold weather, with some areas potentially seeing frost. Residents are advised to exercise caution when traveling through fog-prone areas. The Northeast monsoon continues to cover the Gulf of Thailand, the South, and the Andaman Sea, leading to heavy rain in some parts of the lower South. The lower Gulf of Thailand is predicted to have waves reaching 1-2 meters, with even higher waves in areas experiencing thunderstorms. Sailors are urged to navigate with caution and avoid areas with thunderstorms.
Furthermore, during 26-28 January 2025, a new high-pressure area or cold air mass from China is anticipated to cover the upper part of Thailand and the South China Sea, resulting in colder weather accompanied by strong winds. The Northeastern region is expected to see a temperature drop of 3-5 degrees Celsius, while temperatures in the North, Central region, including Bangkok and its vicinity, the East, and the upper South are likely to decrease by 2-4 degrees Celsius. The northeastern monsoon over the Gulf of Thailand, the South, and the Andaman Sea is expected to intensify, causing increased rain and heavy rain in the lower South. The Gulf of Thailand and the Andaman Sea are projected to experience stronger waves, with waves in the lower Gulf of Thailand reaching 2-3 meters and higher in thunderstorm-affected areas. The upper Gulf of Thailand is expected to have waves approximately 2 meters high, with higher waves in thunderstorm regions.
Weather conditions during this period are expected to impact dust accumulation. Poor air ventilation and weak winds are likely to cause dust accumulation levels to be fairly high to high.
