Bangkok Floods: Both Airports Open but Disruption Continues Across Thailand

Severe flooding has hit Bangkok and surrounding provinces in the second half of September 2026, leaving the Thai capital's streets under water and prompting authorities to declare all 50 of its districts disaster-affected areas. Travellers with trips booked to Thailand are facing road closures, transport disruption and reduced public services.

Thailand is in its monsoon season, which typically runs from June to October, but the flash floods were triggered by more than a month's worth of rain falling in just two days.

Key facts

• 330mm of rain (about 12 inches) fell within 48 hours at the end of last week
• All 50 districts of Bangkok have been declared disaster-affected areas
• Both Bangkok international airports, Suvarnabhumi and Don Mueang, were open on 27 September
• Special public holidays are in force in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan on 28 and 29 September
• UK travel advice against visiting border areas near Malaysia and Cambodia still stands

What has happened in Bangkok?

Major roads have been flooded, with people wading through waist-deep water and cars partially submerged. Bangkok's governor said the conditions pose a "risk to people's lives", and severe damage to private and public property is likely.

Schools have been designated as temporary accommodation for affected residents. People living near canals, the worst-affected areas, have been asked to evacuate and move their possessions to higher ground. The army has set up field kitchens and shelter.

Are flights and airports affected?

Bangkok's main airport, Suvarnabhumi, was particularly badly hit, with passengers facing delays of up to six hours to collect their baggage. However, both Suvarnabhumi and Don Mueang International Airport remained open on 27 September.

Travellers due to arrive at one of Bangkok's airports in the coming days should check their flight status directly with their airline.

What is the latest government travel advice?

The UK government's foreign travel advice page states that severe flooding is affecting parts of Thailand following heavy rainfall in a number of provinces, including Bangkok, Nonthaburi, Pathum Thani and Samut Prakan. Travel disruption, including road closures and flooding of low-lying areas, is possible.

The Thai government has declared special public holidays on 28 and 29 September in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan. Many government offices and services may be closed or operating with reduced capacity. Travellers planning to move around are advised to follow the instructions of local authorities.

Can I get a refund if I cancel my trip?

The UK travel advice page maintains its warning against travel to certain parts of Thailand, namely areas along the country's borders with Malaysia and Cambodia. The flooding has not, however, led to a "do not travel" advisory for the country as a whole, making it unlikely that trips can be cancelled without penalty. Travellers should consult their travel provider directly about cancelling or rescheduling.

What this means for travellers

Anyone currently in, or heading to, Bangkok and the surrounding provinces should expect disruption on the roads, potential flooding in low-lying areas and reduced capacity at government offices during the 28 and 29 September holidays. Checking flight status with the airline and following the directions of local authorities are the practical steps highlighted by official advice.

Further updates will depend on how the flooding develops. No end date for the disaster declaration or the special public holidays has been announced.
