Heavy rain has flooded parts of Bangkok and several nearby provinces. All 50 districts of the Thai capital have been declared disaster-affected areas, although the flooding is more severe in some neighbourhoods than others. The UK Foreign, Commonwealth and Development Office (FCDO) has updated its travel advice for Thailand. It warns that flooded roads and low-lying areas may disrupt journeys in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan.
Around 700,000 people in Bangkok were affected by the weekend flooding, according to the city’s Flood Control Centre. Eastern neighbourhoods have been among the hardest hit, and some residents have had to leave their homes. Floodwater has begun to recede in parts of the capital, but some streets remain inundated. Bangkok’s governor said on Tuesday that clearing the main roads could take another two days, while lower-lying areas could take up to a week.

The rain is expected to ease in much of Thailand, according to the Thai Meteorological Department’s forecast for 29 September. It still warns of isolated heavy rain in northern, central and eastern areas, where further flooding or landslides are possible. Bangkok’s forecast includes scattered thunderstorms. Travellers should therefore check conditions for their specific route, even if the weather has improved where they are staying.
What does the travel advice say?
Bangkok’s disaster declaration does not amount to a ban on visiting the city. The FCDO warns about flooding and possible travel disruption, but it has not advised against travel to Bangkok because of the floods. Its advice against all but essential travel applies to specified areas near the borders with Malaysia and Cambodia for separate security reasons. Travellers should read the warning for the places they plan to visit, rather than treat one advisory as applying to all of Thailand.
The flooding can still make a journey difficult even when a destination is open. A road may be blocked, a taxi may take longer to arrive, or a local service may change its route. The Tourism Authority of Thailand advises visitors to check weather, traffic and public transport before setting out. It also recommends allowing more time for journeys to airports and transport hubs
📍 Bangkok update, 29 September, 13.00 hrs.: Most attractions remain open, both airports are operating and city rail services are running. Some roads are affected by flooding. Check conditions and allow extra travel time.

Are flights still operating?
Bangkok’s two main airports, Suvarnabhumi and Don Mueang, have remained open, but an open airport does not mean every flight is running on time. Thai Airways said on Tuesday that flooding had prevented many staff from reaching work and that it planned to cancel around 30 departures from Bangkok. The airline was also dealing with a large backlog of baggage at Suvarnabhumi. Passengers should check their own flight directly with the airline and allow extra time to reach the airport.

The Thai government declared 28 and 29 September special public holidays in Bangkok and the three neighbouring provinces covered by the FCDO warning. The decision was intended to reduce travel in flood-affected areas. Some government offices and services may be closed or operating with fewer staff, although essential public services are expected to continue. Travellers who need an appointment or assistance from an office should check its opening arrangements before going there.

What if you have a trip booked?
Travellers due to depart soon should check their flight, accommodation and the transport needed to complete the journey. Those already in an affected area should follow instructions from local authorities and avoid travelling through floodwater. Conditions can differ sharply between neighbourhoods, so an update for Bangkok as a whole may not describe the route to a particular hotel. If a booked service is cancelled or cannot be reached, contact the airline or travel provider to discuss the available options.
The FCDO’s flooding warning does not, by itself, establish an automatic right to cancel a holiday for a full refund. What a traveller can recover depends on what they booked, whether a provider cancels a service, and the terms of any insurance policy. Anyone considering changing a trip should speak to the provider before cancelling it themselves. They should also check their policy’s wording and the latest advice for every destination on their itinerary.
