Thailand is forecast to endure five days of heavy rain, thunderstorms, strong winds and possible hail from October 9 to 13, 2026. The Meteorological Department’s second warning outlines which provinces will be affected each day, with the southern region impacted throughout the period. Residents are urged to prepare for flash floods, hail and rough seas and to follow official safety advice.
The Thai Meteorological Department announced on October 7, 2026 that Thailand would experience unstable weather from October 9 to 13, characterized by thunderstorms, strong gusts, hail and periods of heavy to very heavy rain. The warning, the second of its kind (notice 248/2569), outlines daily impacts: on October 9 the lower Northeast and southern provinces; on October 10 the lower North, lower Northeast, Central region including Bangkok and vicinity, East and South; on October 11 the lower North, Central region with Bangkok vicinity, East and South; on October 12 the lower Central region with Bangkok vicinity and South; and on October 13 only the South. The affected provinces listed include, for example, Amnat Charoen, Surin, Sisaket and Ubon Ratchathani in the Northeast on October 9; Rayong, Chanthaburi and Trat in the East on October 10; Phetchabun, Kamphaeng Phet and Tak in the North on October 10; and many central provinces such as Lopburi, Saraburi, Nakhon Sawan, Chai Nat, Sing Buri, Ang Thong, Phra Nakhon Si Ayutthaya, Uthai Thani, Suphan Buri, Nakhon Pathom, Kanchanaburi, Ratchaburi, Samut Sakhon and Samut Songkhram, plus Bangkok and surrounding areas. Southern provinces affected throughout the period include Phetchaburi, Prachuap Khiri Khan, Chumphon, Surat Thani, Nakhon Si Thammarat, Phatthalung, Songkhla, Ranong, Phang Nga, Phuket, Krabi and Trang. The unsettled weather is caused by a cold high-pressure system from China extending over northern Thailand, an upper‑level monsoon trough crossing the upper South, and a persistent southwest monsoon over the Andaman Sea, southern Thailand and the Gulf of Thailand. The department advises the public to guard against lightning, strong winds, heavy rain and possible flash floods, especially in hilly areas near waterways and low‑lying zones, and to avoid sheltering under weak structures or large trees. In the Andaman Sea and Gulf of Thailand, waves may exceed two metres during thunderstorms; mariners should check routes and exercise caution, avoiding travel in stormy areas. For safety, people are urged to plan travel and activities carefully, follow updates from the Meteorological Department via its website (www.tmd.go.th) or hotlines 0-2399-4012‑13 and 1182, which operate 24 hours a day. The next notice will be released on October 8, 2026 at 05:00 local time.
