Urban Flooding Threats
The heavy rain Dhaka flood risk is a pressing concern, particularly in low-lying areas like Gulshan, Banani, and Dhanmondi, where waterlogging has historically disrupted traffic and businesses.

In June 2025, Dhaka recorded 450 mm of rain, nearly double the monthly average, causing knee-deep waterlogging in areas like Mirpur and Uttara.
The rain Dhaka Bangladesh 2025 forecast underscores risks to Dhaka’s drainage systems, which struggle with silted canals despite the city corporation’s BDT 160 million investment in 2024 for excavation. Areas like Tejgaon and Motijheel face heightened heavy rain Dhaka flood risk due to poor drainage and urban sprawl, with: 30-40% of roads potentially inundated during intense showers.
Health and Infrastructure Impacts
The heavy rain Dhaka flood risk also amplifies public health concerns, with waterborne diseases like dengue and diarrhoea surging post-monsoon. In July 2025, Dhaka reported 2,500 dengue cases, with hospitals in Gulshan and Banani on alert. Stagnant water from heavy rains increases mosquito breeding, while sanitation issues in informal settlements heighten risks. The Dhaka North City Corporation has deployed anti-mosquito spraying, but shortages of fogging equipment persist.
Infrastructure faces strain, with power outages reported in 15% of Dhaka’s wards during June’s heavy rains. The dhaka monsoon rain updates 2025 note disruptions to waterway transport and markets, with vegetable prices rising 20% due to supply chain issues.

Community volunteers in areas like Rampura are organizing sandbag barriers, while schools in flood-prone zones like Khilgaon may face closures if rainfall exceeds 50 mm in 24 hours.
Background
Dhaka, home to 20 million, is among the world’s most climate-vulnerable cities, with monsoons contributing 70% of its 1,900 mm annual rainfall. The 2025 monsoon, one of the strongest since 1981, began early in May, with Teknaf recording 1,144 mm in June and 1,384 mm in July, far above averages. Low-pressure systems in the Bay of Bengal, intensified by climate change, have triggered frequent heavy rains, with 13 marine cautionary signals issued since May 2025. Past monsoons, like 2024’s, saw flash floods displace: 50,000 in Dhaka, highlighting systemic drainage issues.
What’s Next for Dhaka Monsoon Rain Updates 2025
The BMD predicts rainfall may intensify through Tuesday, September 9, 2025, with a low-pressure system potentially forming in the Bay of Bengal.
