A heads up if you're looking to cool off this weekend.
Niagara Region Public Health has listed three beaches as unsafe for swimming.
Due to the presence of algae, Waverly Beach in Fort Erie has been listed.
Queen's Royal Beach in Niagara-on-the-Lake has been cited for safety issues.
As well, Long Beach in Wainfleet is listed as unsafe, due to E.coli.
