It is a cloudy and cool final Sunday of spring in Ottawa, but record-breaking warm temperatures will arrive this week as the calendar turns to summer.

It is a cloudy and cool final Sunday of spring in Ottawa, but record-breaking warm temperatures will arrive this week as the calendar turns to summer.

"That's coming," Environment Canada senior climatologist David Phillips said.

"We're going to see temperatures go right up into the 30s. It's going to be really the first real test of summery-like weather."

Summer officially arrives in Ottawa at 10:57 a.m. Wednesday.

Environment Canada's forecast calls for a high of 29 C Wednesday, with temperatures expected to hit 33 C on Thursday and 34 C on Friday and Saturday.

"Nature is paying attention to the time and we're going to see warm temperatures; several days where the temperature is going to get above 30," Phillips told Newstalk 580 CFRA's CFRA Live with Andrew Pinsent this weekend.

"I would guarantee that people in Ottawa would not be complaining about the smoke, they'll be complaining about the heat and the haze and the humidity."
