Thailand Issues Heavy Rain and Rough Sea Alerts
The Thai Meteorological Department has issued warnings for heavy rainfall across multiple regions and high waves in the Andaman Sea and Gulf of Thailand.
On July 30, 2026, the Thai Meteorological Department (TMD) released a weather alert regarding the impact of a monsoon trough and a strengthening southwest monsoon. The weather system is currently affecting the North, Northeast, Central, East, and South regions of Thailand.
Weather Forecast
According to the TMD, isolated very heavy rains are expected in the North, East, and the west coast of the South. Meanwhile, the Northeast, Central region—including Bangkok and its surrounding areas—and the east coast of the South may experience isolated heavy rainfall.
Marine Conditions
Sea conditions are significantly affected by rather strong winds. In the upper Andaman Sea, wave heights are forecast to reach 2–3 meters, potentially exceeding 3 meters during thundershowers. In the lower Andaman Sea and the upper Gulf of Thailand, waves are expected to reach approximately 2 meters, with heights exceeding 2 meters in areas experiencing thundershowers.
Impact and Outlook
For residents and travelers, these conditions may lead to localized flooding and disruptions to maritime travel. Those planning trips to coastal areas or islands should monitor local updates closely. While the TMD has provided these forecasts, the exact duration of these weather patterns remains subject to change. Travelers are advised to follow official guidance from local authorities and check for updates before engaging in water-based activities.
