Video by Al Jazeera English | More than 1,000 killed in floods across Indonesia, Sri Lanka as rescue efforts continue
South and Southeast Asia’s 2025 monsoon season has turned into one of the deadliest in decades. A wave of late-season storms, burst rivers and slow-moving rain systems has now killed more than 1,400 people across Sri Lanka, Indonesia, Thailand, Vietnam, Malaysia and the Philippines. Millions have been displaced. Warmer oceans and stalled weather patterns pushed rainfall far beyond normal monsoon levels and left entire regions struggling to recover.
🇱🇰 Sri Lanka: Cyclone Unleashes Nationwide Disaster
Sri Lanka suffered one of its worst natural disasters in years. Cyclone Ditwah dumped torrents of rain on the central highlands and western plains. Entire neighborhoods near the Kelani River were swallowed by floods and mud. At least 355 people have died. 366 are missing. The military used helicopters and boats to reach families trapped on rooftops. More than one million people were affected as landslides cut off roads and power for days. Sri Lanka’s president says this has been the most difficult rescue operations in the country’s history.
🇮🇩 Indonesia: Villages Swept Away on Sumatra

🇹🇭 Thailand: Record-Breaking Rains and Surging Rivers
Updated Dec 5 | Thailand suffered one of its most startling disasters in years when Hat Yai, long viewed as floodproof, collapsed under extreme weather. Over three days, the city was hit by record-shattering storms, including the heaviest one-day rainfall in 300 years. Runoff from nearby hills surged into the city, canals overflowed and drainage systems failed. Some neighborhoods sat under 8.2 feet of water. Deaths are estimated in the hundreds.

More than 150,000 people were affected across the district. Schools closed. Eight hospitals shut down. The economic engine that contributes 2.6 percent of Thailand’s GDP came to a halt. Damages may exceed $780 million. The disaster exposed how rapid development diverted natural runoff routes and revealed the limits of Thailand’s most advanced flood-prevention systems.
🇻🇳 Vietnam: Landslides Across the Central Provinces
Vietnam was devastated by flooding in October and November, especially in Đắk Lắk, Khánh Hòa, Lâm Đồng, Quảng Nam, Quảng Ngãi and Phú Yên. Around 90 people died. Mountain roads collapsed. Entire hillsides fell away, burying homes. Coffee farms across the Central Highlands faced major losses, raising long-term economic risks.

🇵🇭 Philippines: Monsoon and Typhoons
The Philippines was hit twice in 2025. First, July monsoon floods inundated communities in Bulacan, Pampanga and Cavite, killing dozens and disrupting transport across Metro Manila. Then in November, Typhoon Kalmaegi and Super Typhoon Fung Wong tore across Luzon and parts of the Visayas, forcing more than one million people to evacuate. Storm surges swept through coastal towns. Rivers flooded inland areas that were already weakened from earlier storms.

🇲🇾 Malaysia: Rural Districts Cut Off as Rivers Burst

🌡️ Why 2025 Became One of the Worst Seasons
Several forces combined to create a catastrophic season. Late storms hit when soils were already soaked. Some systems stalled for days, unleashing extreme rainfall. Sea temperatures in the Indian Ocean and western Pacific were warmer than usual, adding moisture to every storm. Scientists say these conditions are consistent with long-term climate warming and will likely make extreme flooding more common.
🔧 Rebuilding and Recovery
Governments across South and Southeast Asia are now moving from rescue to recovery. More than 1,000 deaths have been confirmed, and the number is still rising as missing persons are counted. Millions of people have been displaced. Officials are calling for stronger warning systems, better drainage and more climate-resilient infrastructure. Communities are clearing debris, rebuilding homes and restoring farmland damaged by landslides and repeated flooding.
🌧️ Outlook: More Severe Rain Possible
Weather agencies warn the wet season is not over. Heavy rainfall is still possible in parts of Sri Lanka, Indonesia, Malaysia and southern Thailand. With soils saturated and bridges weakened, even moderate storms could trigger new floods or landslides. The region remains on high alert as cleanup and recovery continue.
