Thailand
22 June 2026 - 28 June 2026The southwest monsoon prevailed over the Andaman Sea, Thailand and the Gulf of Thailand throughout the week, weakening at the beginning of the week, then moderate, and strengthening on the last day of the week. Additionally, the low-pressure cell covered upper Vietnam almost the week. Moreover, the monsoon trough lay across Myanmar, upper Laos and upper Vietnam before shifting southward to lie across upper northern and upper northeastern of Thailand on the last day of the week. These conditions caused rainfall over Thailand, mainly in the central, eastern and southern west coast regions at the middle and the end of the week.
