Thailand
13 January 2025 - 19 January 2025The strong high-pressure area from China covered upper Thailand and the South China Sea on the first day of the week before weakening. Subsequently, another rather strong high-pressure area extended its ridge to dominate these regions in the second half of the week. These conditions resulted in cool to cold weather in upper Thailand, with particularly cold weather in the northern and northeastern regions for most of the week, including very cold weather in some areas at the beginning of the week. The central and eastern regions experienced generally cool weather almost the week, with cold weather in several areas. In the southern region, cool weather was observed in several areas, accompanied by rainfall primarily in the middle of the week due to the influence of the rather strong northeast monsoon prevailing over the Gulf of Thailand, the southern region and the Andaman Sea during this period.
