Thailand weather: Rising temperatures as cold air mass weakens
The Thai Meteorological Department (TMD) forecasted that the moderate cold air mass covering upper Thailand is weakening, leading to rising temperatures. Rain is expected in the south on January 20.
The current high-pressure system over upper Thailand and the South China Sea is diminishing, resulting in higher temperatures and morning fog. Northern and northeastern regions will experience cold to very cold weather, while the central region, including Bangkok and its vicinity, the eastern and upper southern regions, will have cool mornings.
Mountainous areas will face very cold conditions with some frost. Residents are advised to maintain health precautions due to the persisting cold and to be cautious of fire hazards due to dry conditions. Caution is also advised when travelling through fog-prone areas.
The winter season remains, with the TMD predicting a mix of cold and rain for the next 15 days. The moderate northeast monsoon affecting the Gulf of Thailand, the south, and the Andaman Sea is weakening, resulting in reduced rainfall in the south.
Waves in the lower Gulf can reach 1 to 2 metres, and in stormy areas, waves may exceed 2 metres. Fishermen are advised to navigate with care and avoid stormy areas.
Current weather conditions are affecting dust accumulation, with poor to weak air ventilation and weak winds over upper Thailand. This, combined with continuous surface inversion, limits the dispersion of air pollution, leading to an expected increase in dust concentration.
