The weather felt like 35 degrees Sunday and will get close to 40 degrees with the humidex by Tuesday, with the heat warning from Environment Canada being extended until at least Wednesday The hot weather is not supposed to break until at least Thursday or even Friday.

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.

Durham Region Health Department advises protective actions during the heat warning:

  • There are ways to keep your home cool even without an air conditioner. Close curtains or blinds during the day, open windows to cool your household in the evening, use a fan.
  • If you must work outside or do physical activity outdoors, take extra breaks, drink lots of water and wear less gear, if possible.
