Heavy rain and strong winds expected across Thailand during June 10–13

TUESDAY, JUNE 10, 2025

Widespread rain and isolated heavy showers are forecast nationwide, with very heavy rainfall possible in the East and along the western coast of the South

A moderate monsoon trough is currently extending across the North and upper Northeast of Thailand into a low-pressure cell over upper Vietnam. Meanwhile, a rather strong southwest monsoon continues to prevail over the Andaman Sea, the South, and the Gulf of Thailand, bringing increased rainfall across the country, the Thai Meteorological Department announced on Tuesday.

Widespread rain and isolated heavy showers are forecast nationwide, with very heavy rainfall possible in the East and along the western coast of the South, the department said.

Residents in these areas are advised to beware of flash floods and runoff, particularly in low-lying areas and near foothills or waterways. Farmers are urged to take preventive measures to protect crops from damage.

In the Andaman Sea and upper Gulf, waves are expected to reach 2–3 metres, and may exceed 3 metres in areas with thundershowers. In the lower Gulf, waves will range from 1–2 metres, and exceed 2 metres during storms.

All vessels in the Andaman Sea and the Gulf are advised to navigate with caution and avoid sailing through thundershowers. Small boats in the Andaman Sea and upper Gulf should remain ashore until at least June 13, the department warned.

Additionally, an active low-pressure system over the upper South China Sea is expected to intensify between June 10–13, potentially affecting weather patterns in the region, the department added.
