Most towns in Durham will keep splash pads open until sunset. Camp Samac outdoor pool in Oshawa will also stay open until sunset and Lakeview Park Beach will extend lifeguard supervision hours to allow residents and visitors plenty of time to stay cool.

All beaches on Lake Ontario are open this week.
