Warning Issued for Copenhagen Swimmers After Heavy Rain Forecast

Residents and visitors in Copenhagen Municipality are advised to exercise caution when swimming in the coming days. Hofor issued the warning following a yellow alert from the Danish Meteorological Institute (DMI) predicting heavy rain and thunderstorms across much of the country. The concern is that large volumes of rain can overwhelm sewage systems, leading to overflows that contaminate bathing water. Such contamination poses a risk of illness to swimmers.

Hofor recommends that people be particularly vigilant about bathing water quality for a couple of days after significant rainfall, especially in harbors or urban beaches. The utility company suggests consulting the website badevand.dk for current water quality status at specific locations. Kalundborg Municipality has also issued similar warnings, urging individuals to assess conditions before entering the water.

Concerns include murky or discolored water, which could indicate pollution or an increase in algae. Both Hofor and Kalundborg Municipality emphasize that if there is any doubt about the water quality, it is best to refrain from swimming. Municipalities are responsible for regular water quality measurements, and information is often available at local swimming spots, sometimes indicated by bathing flags.
