Heavy Rains Swamp Northern Vietnam, Disrupt Travel and Displace Thousands

Heavy rain fell across northern and north-central Vietnam in mid-September 2026, pushing several rivers above dangerous levels and inundating large swaths of land. The disaster prevention department reported that some locations received more than 50 cm (19.7 in) of rain during the week, while a government statement noted that downpours since September 14 delivered as much as 653 mm in the hardest-hit areas. By September 17, streets in Hanoi were flooded to nearly one metre deep, and the Bui River’s rise threatened homes on the city’s southwestern fringe.

Vietnam is among the world’s most climate-vulnerable nations and experiences annual flooding. The country endured a series of severe storms in 2025, including Tropical Storm Wipha, Tropical Storm Kajiki and Typhoon Bualoi, which together caused extensive damage. Those events prompted authorities to seek new flood-management strategies, but the September 2026 rains again overwhelmed existing defenses.
