A mass of cold air from China will cause thunderstorms followed by a marked drop in temperatures in Thailand from February 8 to 11.

Sea conditions in the Gulf of Thailand and the Andaman Sea will be moderate, with waves of around 2 meters in the lower part of the Gulf.
In areas affected by storms, wave height could exceed 2 meters due to the northeast monsoon covering the Gulf of Thailand, the southern region and the Andaman Sea.
