Largely forgotten by the public, politicians and the media, the flood crisis that Hat Yai, the largest city in the south of Thailand, experienced in November 2025 is far from over. The waters have receded, but the recovery has only just begun.
That the flood occurred should not have come as a surprise. Hat Yai has experienced devastating floods before, particularly in 2000 and 2010. The south of Thailand experiences seasonal heavy rainfall events, but with this being a La Niña year, additionally heavy rainfall was widely predicted.
This time the flood came in two waves, with three-day accumulated rainfall reaching 630 millimetres (nearly 25 inches). On the morning of Nov. 21, it appeared the worst was over.
According to Khun Nit, a 70-year-old resident of the low-lying Khet 8 area of Hat Yai, the streets were flooded just below knee level, but this appeared to be the full extent of the flooding. He was out in the street in front of his house posing and taking photos with his wife standing in the water, all smiles. This level of flooding is not uncommon, and while certainly a major inconvenience, nothing out of the ordinary.
By the early hours of Nov. 22, heavy rain had begun to fall again, and through to the next day the floodwaters rapidly rose. At the same time, the news coming from the local government was that everything would be fine. The nearby warning system of colour-coded flags on a bridge in front of the local district offices remained at green, and it was generally assumed there was no need for concern, and no need to move possessions to higher floors or other safe areas.
“If we’d had warning I would have moved my possessions, but the flag stayed green,” a middle-aged man who lived near the early-warning system told me.
A young man selling barbecued food on the street said his father in a province near the Malaysian border had told him to evacuate, but he felt confident in the local government advice that the city would be fine and decided to stay.
Within a matter of hours, the floodwaters rose dramatically, forcing people to rush to safety. Across the city, the water reached a story high, about 3-4 meters (10-13 feet), while in some low-lying areas it reached 8 m (26 ft).
Khun Nit and 14 other people moved to a neighbour’s two-story house, not realising this would be their shared home for the next six nights.
Everyone we spoke to had similar experiences. For those in single-story houses, including a single father of two young children, there was a desperate scramble just to get out of the house in time — escaping by forcing a hole in the tiled roof of his rented house, taking only the clothes on their backs and camping out with 30 others on the second floor. Neighbours, friends and family became the only source of relief, escape and shelter.
Flooding knocked out the electricity and phone services. The current of the huge volume of water, sweeping cars, motorbikes and all kinds of rubbish, was impossible to navigate, and with no means of communicating with the outside world, people were left completely to their own devices, not knowing how long it would last or how long they would be on their own.
