Bangladesh 2025 Monsoon Flood Crisis Bangladesh’s monsoon flood crisis escalated in mid-2025 after heavy rainfall, upstream runoff from India, and flash flooding affected multiple regions, especially the southeast and northeast. ReliefWeb said the crisis began in mid-May 2025 and by 1 June several districts including Sylhet, Sunamganj, Moulvibazar, Habiganj, Netrokona, Noakhali, Bhola, Khagrachari, Bandarban, and Rangamati were severely affected. The Asian Disaster Reduction Center also described the outbreak as triggered by heavy monsoon rainfall and upstream water flow from India.
By early-to-mid July, reporting showed a sharp deterioration in the southeast. Reuters reported on 11 July 2025 that at least 44 people had died and more than one million were stranded across seven districts, with 267,918 households disrupted; the affected districts were Chattogram, Cox’s Bazar, Bandarban, Rangamati, Khagrachhari, Moulvibazar, and Habiganj. Prothom Alo later cited the Ministry of Disaster Management and Relief as saying 51 people had died, 1,022,963 people were affected, and 267,918 families were stranded, with Cox’s Bazar recording the highest death toll. ReliefWeb’s 10 July update also reported 63,860 stranded families in Noakhali and 15,350 people affected in Feni-area flooding, while the UN Bangladesh situation report later stated that about 436,000 people required humanitarian assistance and 59 deaths had been reported in the seven most affected districts as of 22 July 2026.
The crisis has also had a severe impact on Rohingya refugee camps in Cox’s Bazar, where reporting in early June 2025 described landslides, damaged shelters, and fatalities among refugees. Government and humanitarian responses included army and navy boat deliveries of food, water, and medicines, alongside cash and rice distributions to affected communities.
