Public Health is advising swimmers to avoid Waverly Beach, Nickel Beach and Long Beach
The region's under a heat warning, and if you plan to go swimming, there are a few beaches you need to avoid.
Public Health says algae has been found at Waverly Beach in Fort Erie and Nickel Beach in Port Colborne.

Throughout the summer, Public Health frequently tests the water at local beaches, to make sure it's safe for swimmers.
