Could we see Canada reach this first summer threshold of the year this weekend?
Some warm days have made an appearance in many provinces, but one threshold just hasn’t been reached yet in Canada: 30°C! But that could change this weekend for a lucky region
Forecasters were expecting to see April end in Ontario with Canada's first 30°C reading as a mass of warm, humid air moved over the southern reaches of the province on the 29th. While the warmth certainly felt like summer—especially with the damaging storms that followed—the warmest temperature recorded ended up being just shy of that 30 degrees.
Egbert, Ont., reached a high of 28.8°C on Tuesday, capturing the title of the warmest temperature recorded in Canada so far in 2025. But a cold front, which served as the trigger for Tuesday's stormy weather, has cooled things down quite substantially across southern Ontario.

Now our eyes are turning to the Prairies for the weekend heat as an upper ridge slides over the three provinces.
Most major cities across the Prairies have already reached the 20°C threshold for the year; that is, except for Calgary.
So far, the warmest daytime temperature recorded on the Prairies is 24.8°C—a record currently held by Medicine Hat.
Prairies on the hunt for Canada's first 30°C day of 2025
A taste of summer is on the way for the Prairies as temperatures start to ramp up on Friday in Alberta, with Saskatchewan and Manitoba following closely behind on Saturday.
Temperatures across Alberta are expected to warm up into the mid-20s, and we may even see the first 25°C reading of the year for the province.
The building heat will continue to spread east into Saskatchewan and Manitoba on Saturday, which is when we're most likely to see some thermometers reach 30°C—most likely somewhere around the Alberta-Saskatchewan border.

The heat will keep moving eastward on Sunday, leading to a dramatic decrease in temperature across Alberta, but leaving Saskatchewan and Manitoba with another chance at a 30-degree day. Sunday's hotspot will be limited to a smaller area around the borders between Saskatchewan, Manitoba, and North Dakota.
Both Saturday and Sunday do hinge on the temperatures warming up slightly more than anticipated; however, the highs on both days are forecast to stay just under 30 degrees.
After such a warm and summery weekend to start off May, we'll see temperatures dip back to seasonal for the beginning of the work week. The temperature rollercoaster across the Prairies is then expected to continue through the long range.
