Heavy rainfall and gusty winds are forecast across 17 Thai provinces on 28 October 2026, according to the Thai Meteorological Department.
The weather pattern stems from a high-pressure system extending from China over upper Thailand and the South China Sea, which is generating prevailing easterly winds across the mainland. Simultaneously, a low-pressure cell over the Andaman Sea is drawing moisture across the southern peninsula. These interacting systems will produce isolated severe thundershowers in central regions and sustained downpours in the south.
Bangkok and the Central Region
The capital faces scattered thundershowers alongside sudden wind gusts throughout the day. Temperatures in Bangkok are expected to range between 25°C at night and 35°C during the afternoon, with easterly winds moving between 10 and 20 kilometres per hour.
Similar conditions apply across surrounding central provinces, where isolated heavy downpours are forecast for Kanchanaburi, Ratchaburi, Nakhon Pathom, Samut Sakhon, and Samut Songkhram. For British residents commuting across the Bangkok Metropolitan Region, intense rain during peak hours frequently causes rapid water accumulation on secondary roads and pavements. Public transport networks, including the elevated train systems and underground routes, usually maintain normal schedules, but road traffic and app-based taxi bookings face severe delays during heavy squalls.
Southern Provinces and Maritime Conditions
The south faces the heaviest rainfall, with widespread thundershowers expected across both coasts.
On the Andaman coast, heavy showers will affect Ranong, Phang Nga, Phuket, Krabi, and Trang. Temperatures will peak around 33°C. Wind speeds will reach up to 35 kilometres per hour, generating open-sea waves between one and two metres, which will exceed two metres in storm areas.
On the Gulf coast, downpours will cover provinces from Phetchaburi and Prachuap Khiri Khan down to Chumphon, Surat Thani, and Songkhla. Wave heights will also exceed two metres during thundershowers. UK nationals residing in coastal districts or travelling between mainland ports and islands should prepare for potential ferry disruptions. Operators often alter crossing timetables or suspend smaller passenger vessels without long notice when squalls develop.
Eastern Seaboard, North, and Northeast
Eastern provinces, including Chon Buri and Rayong, will experience scattered thundershowers with gusty winds and daytime temperatures up to 35°C. Offshore waves will exceed two metres during localised storms.
In the north and northeast, rainfall will be less widespread. Isolated showers will affect northern areas such as Chiang Mai, Mae Hong Son, and Tak, alongside northeastern provinces including Nakhon Ratchasima and Buri Ram. Minimum temperatures in these upland regions will drop to between 21°C and 25°C, signalling the seasonal transition as autumn draws to a close and the dry winter air mass edges south from mainland Asia.
Practical Considerations for British Residents
Late October marks the shift from the southwest monsoon to the cooler northeast monsoon across Thailand.
During this changeover, sudden storms present several practical issues for expatriates managing property and domestic routines. Residents living in high-rise buildings should secure outdoor furniture and clear balcony drainage points, as wind-driven rain can quickly pool and enter residential units through sliding doors.
Drivers should check tyre tread and windscreen wiper blades, as surface oil on tarmac makes road surfaces especially slick during the first twenty minutes of rainfall. Those planning domestic road journeys across southern routes should monitor local departmental updates for localised flooding alerts.
