Bangkok Flood Disaster Declared as Heavy Rain Swamps City

BANGKOK, September 27, 2026: The Bangkok flood disaster declaration now covers all 50 districts of Thailand’s capital. City authorities made the move on Saturday, September 26, after almost 48 hours of heavy rain flooded homes, shops and major roads. In some neighbourhoods, residents had to wade through waist-deep water.

Meanwhile, Prime Minister Anutin Charnvirakul cut short a trip to London and returned home. He had been leading an investment roadshow there and came back early to monitor the flood response. According to officials, around 300 millimetres of rain fell in some areas between Thursday afternoon and Saturday morning.

Bangkok Flood Disaster Declared in All 50 Districts

The Bangkok Metropolitan Administration (BMA) issued the declaration to give local organisations special powers to act. As a result, the city, other state agencies and local offices can now respond faster and in a more organised way in affected areas. Bangkok Post

However, the whole city is not underwater. Officials covered all districts mainly so authorities could respond quickly, even though some areas stayed dry.

On Saturday afternoon, Bangkok Governor Chadchart Sittipunt said the situation had “stabilised.” He added that if the rain stops, crews expect to drain the floodwater in two to three days.

Why the Bangkok Floods Became So Severe

The main problem is the city’s canal network. Nearly nonstop rain since Thursday afternoon filled the canals, so murky water spilled into nearby homes, restaurants, shops and alleys.

“Our problem is that the canals are full,” the governor said. For this reason, the city is working with nearby provinces to send water out through other routes and reduce the flow into Bangkok.

In addition, the BMA said its pumping stations were running at full capacity. Together, they were moving about 1,200 cubic metres of water per second.

Geography also plays a role. Bangkok, once called the “Venice of the East,” sits on former marshland. Moreover, the city lies only about 1.5 metres above sea level.

A Much Wetter September Than Usual

September is the peak of Bangkok’s rainy season. Still, this year has been far wetter than normal. The city’s drainage and sewerage department recorded 487 mm of rain between September 1 and 25. By comparison, the average for the same period from 1991 to 2020 was almost 269 mm.

Scientists warn that extreme weather will become stronger and more frequent as fossil fuel emissions continue to heat the planet.

How Residents Are Coping With the Bangkok Flood

For many residents, daily life has stopped. Somkid Pheuk-ngam, a 67-year-old vendor who lives near a canal north of central Bangkok, has kept her shop closed for two days. “It’s like at my waist level now,” she said of the water.

Similarly, 63-year-old Anutin Meechamnan said he had never seen rain continue for days like this in all his years in the city.

In Suan Luang district in eastern Bangkok, office worker Khem Amnueilaph, 36, said the water in his area rose above knee level. His new house sits on higher ground, but some older homes nearby have flooded. He has food for two to three days, yet he does not know how he will get to work on Monday.

Across eastern Bangkok, people pushed motorcycles through deep water, and parked cars sat partly underwater on one major road. In Bang Bua district, a woman tried to save goods from her shop as the water reached her thighs. Meanwhile, some convenience stores ran out of stock by lunchtime as people rushed to buy essentials.

Shelters and Emergency Response to the Bangkok Flood Disaster

On Saturday, the governor said at least 13 major roads were flooded. Even so, he told residents not to worry about food shortages. “The public don’t have to be panicked,” he said.

At that time, around 980 people were staying in temporary shelters. Authorities also moved 36 bedridden patients to hospitals, and the city prepared one million sandbags.

Since then, the numbers have grown. According to the governor, the city has now opened more than 200 shelters, and about 4,200 people have moved in. In addition, the army is setting up shelters and field kitchens, while the BMA is using schools as temporary housing and asking people to avoid unnecessary travel.

Schools will close on Monday. Also, authorities have asked some officials to work from home to keep traffic off flooded roads.

The floods are not limited to the capital. The Department of Disaster Prevention and Mitigation reported flooding in 21 provinces on Saturday and expects more rain on Sunday. Nearby, Pathum Thani province also declared Rangsit municipality an emergency disaster zone.

For many Thais, the situation brings back memories of 2011. That year, widespread floods across the country killed more than 500 people and damaged millions of homes.

What Happens Next in the Bangkok Flood Disaster
