The advice comes after water samples have been analyzed and the municipality advises against swimming in Sundbyholm, which is one of the most popular bathing spots in the municipality.
- It's typical when we look like we'll have great weather this weekend, says Peter Fröjdfeldt at the Culture and Leisure Administration.
Bacteria in the water
The municipality tests continuously and each water sample is assessed after the content of the bacteria E.coli and enterococci in the water has been analysed.
The water is judged to be unfit for use if high levels of either or both bacteria were present.
Temperatures of up to 30 degrees are expected this weekend.
Signs advising against swimming have now been put up.
New samples will be taken on August 15 and then a new assessment will be made.
