Sweltering heat is expected to peak today in Ottawa, but full relief isn’t expected until Tuesday night.
An Environment Canada heat warning remains in effect, with temperatures expected to reach 35 C this afternoon. The humidex will peak at 46.
“The first significant heat event of the season with dangerously hot and humid conditions is expected to continue into the week,” the agency said.
With overnight temperatures only dipping to 22 C to 25 C, there will be “little relief from the heat” early this week.
Environment Canada and Ottawa Public Health are both advising against strenuous outdoor activity. They also stressed the importance of staying hydrated, and to pay attention for signs of heat illness.
“Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. Stop your activity and drink water,” Environment Canada said.
The baking temperatures have also forced Ottawa to issue a city-wide burn ban.
“All open air fires are prohibited during a ban, including properties that have an Open Air Fire Permit. This ban applies to agricultural burns, brush pile burns, as well as campfires,” the city said in a statement. “There will be zero tolerance enforcement during the fire ban.”
Wednesday will again be hot with a high of 28 C, but temperatures will drop to 16 C overnight. Rain is forecast for Thursday and Friday, with highs of 22 C and 23 C and lows of 14 C and 15 C.
