Amsterdam Issues Swimming Warning After Heavy Rain Causes Water Pollution

DATELINE: Amsterdam, September 10, 2026

Authorities in Amsterdam have advised residents and visitors against swimming in the Amstel and several city canals following heavy rainfall.

The warning was issued after substantial rain caused wastewater to enter open water in parts of the city. The municipality has advised people to avoid swimming in affected locations until the water quality improves.

Heavy rainfall can temporarily overwhelm urban drainage and sewage systems, increasing the possibility that polluted water reaches canals and other waterways.

The warning is expected to remain in place until the morning of Saturday, September 12, according to information from the City of Amsterdam.

Officials have urged residents to follow local water-quality advice and avoid entering water where a negative swimming recommendation is in force.

The incident highlights the importance of monitoring water quality following periods of unusually heavy rainfall, particularly in densely populated urban areas.
