Thailand
21 April 2025 - 27 April 2025The heat low-pressure cell covered upper Thailand almost the entire week, while the high-pressure area from China extended its ridge over Vietnam and the South China Sea at the end of the week, accompanied by the confluence of southeasterly and southwesterly winds prevailing over the northern, northeastern and central regions during that time. Additionally, southerly and southwesterly winds prevailed over upper Thailand at the beginning and middle of the week. These conditions resulted in generally hot weather throughout the week, with very hot weather observed in some areas. Rainfall mainly occurred at the end of the week. In the southern region, heavy to very heavy rainfall was reported, particularly along the west coast, which experienced abundant rain throughout the week. This was influenced by the prevailing southwesterly wind over the Andaman Sea, the southern part and the Gulf of Thailand, as well as southeasterly winds prevailing over the Gulf of Thailand, the southern region and the Andaman Sea on certain days.
