Thai Meteorological Department Forecasts Thundershowers Through November 6

Key summary

The Thai Meteorological Department predicts thundershowers in Thailand from November 1 to November 6, 2026. The Central region, including Bangkok, the East, Northeast, and South are particularly affected. A high-pressure system from China over upper Thailand and the South China Sea has weakened but brings easterly winds. An easterly wave moves across the lower Northeast, East, Central region, Gulf of Thailand, and South on November 3–5. People should avoid open areas, large trees, and unstable billboards due to gusty winds. Heavy rain may cause flash floods, rapid run-off, and mudslides on foothill slopes near waterways and in low-lying areas. Waves in the Gulf of Thailand and Andaman Sea will exceed 2 metres. Mariners should check routes and avoid thundershower areas; all vessels including small boats must avoid these zones.
