Thailand Issues Heavy Rain and Rough Sea Alert
The Thai Meteorological Department has issued a weather warning for heavy rainfall and high waves across several regions due to a strengthening southwest monsoon.
On August 4, 2026, the Thai Meteorological Department (TMD) released an official weather alert regarding a strengthening southwest monsoon affecting the Andaman Sea, Thailand, and the Gulf of Thailand. The weather pattern is influenced by a monsoon trough extending across the upper North and upper Laos into a low-pressure cell near the coast of upper Vietnam.
Residents and travelers should anticipate isolated heavy to very heavy rainfall in the Northeast, while the North, East, and South regions may experience isolated heavy rains. These conditions are expected to impact maritime activities significantly. In the upper Andaman Sea, wave heights are forecast to reach 2–3 meters, potentially exceeding 3 meters during thundershowers. Meanwhile, the lower Andaman Sea and the upper Gulf of Thailand are expected to see waves of approximately 2 meters, rising above that threshold in areas affected by storms.
For those currently in or planning to visit these regions, it is important to monitor local weather updates closely. While the TMD has provided these forecasts, the exact duration and intensity of the rainfall in specific provinces remain subject to change. Travelers are advised to exercise caution near coastal areas and follow guidance from local authorities regarding maritime safety and potential travel disruptions.
