Khao Lak, Thailand – Heavy rains on 22 October 2025 triggered a sudden flash flood that swept through the popular resort town of Khao Lak, forcing hundreds of Thai and foreign tourists to flee as streets, restaurants and hotels were inundated.
Rapid surge overwhelmed shopping strip
The downpour sent water racing down from the Khao Lak hills and into the town centre, where the Khao Lak Centre shopping and entertainment strip was hit within minutes. Local shopkeeper Noppakhun Jaichuai described chaotic scenes, saying the canal “overflowed within minutes” and that he had to shout at customers to run to safety.
Floors, terraces and ground-level businesses were covered by red muddy water. The inundation extended for more than 800 metres through the heart of the tourist zone and in places reached depths of around one metre, leaving a trail of damaged stores and submerged vehicles.
Chaos on Phetkasem Road
Phetkasem Road, one of the main thoroughfares in the area, became impassable in both directions. Strong currents halted small cars and motorcycles and created a traffic jam stretching more than a kilometre, while travellers with luggage waded through the floodwaters to reach their transport.
Local reports said the suddenness of the surge left many visitors — some dining or shopping at the time — little time to react. Authorities and emergency crews were reported to have prioritised helping those trying to reach the airport.
Emergency services mounted rescue and assessment
Teams from the provincial disaster prevention agency, the Khao Lak police and the Khuk Khak municipality responded immediately to assist residents and tourists. Vice-Governor Buncha Thanu-in personally inspected damaged areas, according to local media.
Among the properties affected was the Khao Lak Seaview Resort, where a retaining wall along the canal collapsed. Officials began an initial assessment of structural and commercial damage as cleanup efforts got under way.
Locals call it worst flood in decades
For long-term residents the event had an historic feel. “This is the worst flash flood I have ever seen,” said Jaichuai, who said he had lived in Khao Lak for 30 years.
Authorities warned communities in vulnerable zones to remain on high alert, saying additional flash floods could follow as conditions persisted.
Cause and consequences
Experts and officials suggested the disaster resulted from a combination of extreme rainfall and possibly blocked drainage systems, but investigators were still evaluating the full causes. The provincial authorities were focused on damage assessments and delivering aid to affected people.
The flash flood hit a tourism-dependent area at an inconvenient time, and local officials stressed that guest safety remained their top priority as cleanup and recovery continued.
Local media coverage cited by authorities described the scale of the disruption and relayed calls for vigilance as crews worked to restore access and services.
