Weather Alert: Heavy Rainfall and Rough Seas Expected Across Thailand
The Thai Meteorological Department has issued a warning for heavy rain and high waves due to a monsoon trough and a strong southwest monsoon.
Weather Warning Overview
On July 29, 2026, the Thai Meteorological Department (TMD) issued an alert regarding significant weather patterns affecting the country. A monsoon trough is currently positioned across the upper North and Northeast regions, while a rather strong southwest monsoon is prevailing over the Andaman Sea, Thailand, and the Gulf of Thailand.
Expected Impacts
- Rainfall: Isolated very heavy rains are forecast for the Northeast, East, and South regions. Meanwhile, isolated heavy rains are expected in the North and Central regions, including Bangkok and its surrounding areas.
- Marine Conditions: The strong winds are creating hazardous conditions at sea. In the upper Andaman Sea, waves are expected to reach 2–3 meters, potentially exceeding 3 meters during thundershowers. In the lower Andaman Sea and the upper Gulf of Thailand, wave heights are anticipated to be around 2 meters, rising above that level during storms.
Advice for Residents and Travelers
Those living in or traveling to these regions should exercise caution, particularly regarding potential flash flooding and marine activities. Travelers planning boat trips in the Andaman Sea or the Gulf should monitor local updates closely, as conditions may change rapidly.
Status
This forecast is based on the latest data from the TMD. Residents are advised to stay updated through official channels for further developments or specific regional warnings as the weather system progresses.
