Weather Alert: Heavy Rainfall and Rough Seas Forecast Across Thailand
The Thai Meteorological Department has issued warnings for heavy rain across the South and potential thundershowers in upper Thailand, including Bangkok.
The Thai Meteorological Department (TMD) has issued an official weather alert effective as of October 28, 2026, regarding unstable weather conditions across the country. According to the TMD, a low-pressure cell currently positioned over the Andaman Sea, combined with prevailing easterly winds, is impacting Thailand and the Gulf. Simultaneously, a high-pressure system originating from China is covering upper Thailand and the South China Sea.
For residents and travellers, these conditions mean that continuous rainfall is expected, with isolated heavy to very heavy downpours forecast specifically for the Southern region. In the upper parts of the country, including the Central region and Bangkok and its vicinity, isolated thundershowers accompanied by gusts are possible.
Marine conditions are also affected; the TMD warns that waves in the Andaman Sea and the Gulf of Thailand are expected to exceed 2 meters in height within areas experiencing thundershowers. Those planning maritime activities or travel in these regions should exercise caution and monitor local updates. While the forecast provides a clear outlook on the current meteorological patterns, the exact duration and intensity of these localized storms remain subject to change. Travellers are advised to stay updated through official TMD channels for the latest developments regarding their specific locations.
