Thailand is entering its cool season, with average low temperatures in Bangkok expected to be around 16-18°C, and 14-16°C in nearby provinces, according to the Thai Meteorological Department.
The cool season officially begins on Tuesday, about two weeks later than usual, and will last until late February, as noted by Sukanyanee Yawinchan, the department’s acting director-general. This season is marked by consistently low temperatures in upper Thailand, falling below 23°C, along with a decrease in rainfall.
Ms. Sukanyanee forecasts that the coldest temperatures this winter could reach 6-8°C, particularly in the northern and northeastern regions, with a possibility of frost in mountainous areas. In Bangkok, temperatures are expected to hover between 16-18°C, while surrounding provinces may see lows of around 14-16°C.
In the southern region, cool weather is anticipated in some areas, especially in the north, but heavy rainfall is also expected. Winds in the Gulf of Thailand will be strong, with wave heights reaching 2-3 meters, while waves in the Andaman Sea could reach up to 2 meters.
From November to December, tropical cyclones may affect the Gulf of Thailand and the southern region, potentially bringing heavy to very heavy rainfall. Waves in the Gulf could reach 3-5 meters, raising concerns about storm surges. The public is advised to monitor updates from the Meteorological Department closely.
Air Quality Alert in Bangkok
In Bangkok, PM2.5 dust particle levels exceeded standard values at 36 monitoring stations on Friday, with the highest concentration noted in Nong Khaem district, according to the Center for Air Pollution Mitigation (CAPM).
The city has been experiencing stagnant weather conditions since Friday due to a cold air mass, resulting in increased dust accumulation. The Center recommends the public take steps to reduce PM2.5 levels by minimizing vehicle use, checking air quality on the Air4Thai website, wearing masks outdoors, and avoiding strenuous outdoor activities.
The Meteorological Department has also warned residents north of the Chao Phraya Dam to be vigilant about rising water levels as Tropical Storm Trami approaches China and Vietnam through Monday, which may bring more rain and gusty winds to northern, northeastern, central, and eastern Thailand. Areas likely to experience heavy rainfall include Nakhon Phanom, Mukdahan, Amnat Charoen, Ubon Ratchathani, Sa Kaeo, Chanthaburi, Trat, Phangnga, Phuket, Trang, and Satun.
Rain is also possible in Bangkok, which may help alleviate the dust situation after Sunday.
