PATTAYA, Thailand – While Pattaya remains largely dry, the Thai Meteorological Department (TMD) reports increasing rainfall across much of the country, with heavy showers expected in several provinces. Citizens in Phitsanulok, Phetchabun, Chanthaburi, Trat, Ranong, and Phang Nga are advised to be cautious of flash floods and runoff from mountainous areas. Bangkok and surrounding metropolitan areas may experience thunderstorms in 70% of their territory. Moderate waves and strong winds are expected at beaches and island shores, so beachgoers should exercise caution.
The TMD noted that monsoon troughs over northern and northeastern Thailand, combined with a strengthening southwest monsoon over the Andaman Sea and the Gulf of Thailand, are driving widespread rainfall. Low-pressure systems in the lower north have intensified rain in certain regions, leading to localized flooding and landslides in sloped and low-lying areas.
The department also issued marine warnings: strong waves of 2–3 meters are expected in the upper Andaman Sea, with higher waves in areas experiencing thunderstorms. Smaller vessels are advised to avoid venturing out until August 17. Waves in the lower Andaman Sea and upper Gulf of Thailand are forecasted at 2 meters, rising over 2 meters in thunderstorms.
Regionally, northern Thailand will see thunderstorms in 80% of the area, with heavy rain in provinces including Chiang Mai, Chiang Rai, and Phitsanulok. Northeastern provinces have similar forecasts, with temperatures ranging from 22–32°C. Central and eastern regions, including Chonburi, Rayong, and Trat, will experience thunderstorms and isolated heavy rain, with temperatures between 23–34°C. Southern Thailand, particularly the west coast including Phuket and Krabi, is expected to have heavy showers and strong southwest winds, with waves up to 3 meters in some areas.
Pattaya, however, shows minimal rainfall and remains mostly sunny, providing residents and tourists a temporary respite from the country’s widespread showers.
