The heatwave hitting Alberta will bring hot temperatures, but nothing compared to the Heat Dome of 2021.  

That’s according to Environment and Climate Change Canada, which updated this week’s extreme heat event. 

Over the weekend, the weather agency issued a heat warning for many regions, which expanded to include nearly the entire province. 

High temperatures are expected to reach 30 to 35 degrees in the next few days with some towns in northern Alberta possibly going above 35 degrees. 

While temperatures are quite high, Jennifer Smith with Environment Canada said it won’t be as hot as what much of western Canada experienced in June of 2021. 

“Heat warning thresholds were met and then surpassed by an enormous margin all-time national records were broken,” she said. “This does not happen every year, or even every few years. That was truly an anomalous and extreme heat wave. The highest temperatures forecast for this event are expected to be lower for the areas that saw the worst heat in 2021.” 

That heat event, dubbed the heat dome, happened from June 25 to July 1, 2021.  

During that time, more than 103 all-time heat records were set, including Canada’s highest temperature ever measured in Lytton, B.C. at 49.6 degrees on June 29, 2021. 

In Alberta, the hottest temperature recorded during the heat dome was 41.5 degrees in the Grande Prairie area. 

This current heat wave is happening during the Calgary Stampede where thousands are expected to walk through the gates this week. 

Naomi Nania is a spokesperson with Alberta EMS and says Stampede goers must ensure they are prepared. 

“The biggest thing that we want people to know is just to try and be as preventative as possible,” she said. “Taking spots and spaces inside when possible, making sure that you're hydrated, eating and drinking clear fluids whenever possible. Really looking out for our elderly and children because they are obviously partly susceptible to the effects of heat and sun.” 

Nania also recommended wearing light-colored clothing and loose-fitting clothing, a broad-brimmed hat and ensuring you’re applying and reapplying sunscreen throughout the day. 

With the risk of exhaustion rising during the hot dates, Nania and other health care professionals want to make sure you know the signs of heat-related illnesses. 

“Some of the first signs that you might see are feeling faint or feeling dizzy. That excess sweating and that cool, clammy skin that you might see or feel feeling sick to your stomach or nausea. Having a rapid heart rate is something that can occur,” she said. 

If you witness someone with complete or partial loss of consciousness, who is confused has a high body temperature, or has stopped sweating, call 911 or your local emergency number immediately while waiting for help,” said Peter Barry with Health Canada. “Take measures to cool the person right away by moving them to a cooler place if possible, applying cold water to large areas of the skin or clothing and thinning the person as much as possible.” 

According to the latest forecast, the highest temperatures could reach Alberta by Wednesday with temperatures in the high 20s or low 30s throughout the next couple of weeks.
