BANGKOK, Thailand – Thailand officially entered the winter season on November 9, but temperatures are not expected to drop immediately across the country, according to the Thai Meteorological Department. Nattawut Daendee, Deputy Director-General acting as Director-General of the department, said the seasonal transition marked a change in wind patterns and weather systems rather than an immediate nationwide drop in temperatures.
Actual conditions will depend largely on cold air masses from China, which are expected to move southwards periodically. During the early winter period, some areas may experience cooler weather while others remain hot during the day or continue to see rainfall.
This year’s winter is expected to be less cold than normal, particularly during its early stages, due to El Niño conditions and global warming, which are contributing to above-average temperatures.
However, periods of colder weather remain possible when strong cold air masses from China extend over Thailand. The coldest period is forecast for January 2027, when upper parts of the North and Northeast could see minimum temperatures of 10–13°C. Chiang Rai may experience lows of 9–11°C, while mountain peaks could face very cold conditions and frost.
