Pattaya Warned: Sudden storms possible despite calm breezes, national rain alert issued. (Photo – Pattaya Beach in June) PATTAYA, Thailand – Visitors enjoying the cool sea breeze on Pattaya’s beaches are being warned not to be lulled into a false sense of security, as dark clouds continue to hover above the Eastern Seaboard. Sudden, intense rainstorms may strike at any moment — even when the skies appear deceptively calm. The Thai Meteorological Department (TMD) has issued a nationwide alert, warning of very heavy rainfall in parts of the North, Northeast, East, and western South of Thailand, urging residents and tourists to beware of flash floods and forest runoff, especially in foothill areas and lowlands. This includes Pattaya and surrounding areas in Chonburi province, where conditions remain unstable. According to the 24-hour forecast, eastern provinces such as Rayong, Chanthaburi, and Trat could see severe weather, with wind gusts and waves reaching 2–3 meters — and even higher during thunderstorms. Local authorities are also urging small boats in the Gulf of Thailand and the Andaman Sea to stay ashore until at least June 13, as wave heights could exceed 3 meters in stormy areas. Meanwhile, a tropical depression in the upper South China Sea is expected to intensify into a tropical storm. While it will not directly impact Thailand, it is contributing to the current unstable conditions. Farmers across affected regions have been advised to take precautions to protect crops from flood-related damage. Even if the beach breeze feels pleasant, don’t leave your umbrella behind. Pattaya’s weather remains unpredictable — and a surprise downpour may be just minutes away.
