Bangkok: The Meteorological Department reports that the North and Northeast regions of Thailand will experience cool to cold weather, while the Central and Eastern regions will have cool mornings. The South is expected to have scattered rain.

According to Thai News Agency, a moderate high-pressure system or cold air mass from China is affecting upper Thailand, contributing to the cooler temperatures in the North and Northeast. Residents are advised to take care of their health due to these conditions. Meanwhile, the Central and Eastern regions will also see cool morning temperatures.

The southern region will experience scattered rain due to a moderate northeast monsoon covering the Gulf of Thailand, the southern region, and the Andaman Sea. Mariners are advised to exercise caution as wave conditions in the lower Gulf of Thailand are moderate, with wave heights around 2 meters, and 1-2 meters in the upper Gulf and offshore in the Andaman Sea.

Currently, the accumulation of particulate matter/haze in upper Thailand is at a moderate level due to improved ventilation conditions.
