As the hockey season takes a break, the annual “Battle of Alberta” has shifted from the rink to the weather, revealing stark contrasts between Calgary and Edmonton this summer. While Calgarians are enjoying a dry spell with soaring temperatures, Edmonton is grappling with unprecedented rainfall that has led to significant disruptions and a hefty cleanup bill.
Record Rainfall in Edmonton
This summer has been particularly challenging for Edmonton, where Environment Canada meteorologist Brian Proctor reports that the city has received an astonishing 533.8 millimetres of precipitation from June to July. This figure sets a new record for the summer months, surpassing the previous high of 417.1 millimetres set in 1953. Proctor described the situation as “an amazing amount of moisture,” highlighting the dramatic impact it has had on the city.
July alone accounted for 264.7 millimetres of rain, resulting in flooded streets, damage to homes, and the cancellation of numerous outdoor events and concerts. The City of Edmonton anticipates that storm cleanup costs could range from £20 to £30 million, illustrating the extensive fallout from the summer deluge.
Calgary’s Dry Spell
In stark contrast, Calgary has experienced one of its driest Julys on record, with only 10.4 millimetres of rain throughout the month. Proctor noted that much of Calgary’s precipitation in June, totalling 108.1 millimetres, occurred during just two significant storm events. Since then, the city has remained largely dry, with limited moisture available to stimulate further thunderstorm activity.
This dry weather has allowed Calgarians to bask in temperatures that have been well above seasonal averages. As the August long weekend begins, residents are enjoying warm weather in the low 30s, prompting Environment Canada to issue a heat warning for the area.
Storms Fueling Edmonton’s Weather Chaos
The relentless storms that have plagued Edmonton this summer have been described by Proctor as “very convective,” leading to extreme downpours that are both intense and localized. Each storm seems to build upon the last, with the meteorologist likening moisture to “gasoline” for thunderstorm development. As such, the storms have repeatedly impacted the same areas, creating a cycle of rainfall that has left many residents reeling.
Forecasts for Edmonton remain bleak, with a mix of sun and clouds expected in early August, alongside a 30 per cent chance of further showers. Meanwhile, the city prepares for more storms, with the weekend forecast indicating a 60 per cent chance of rain and cooler temperatures.
The Impact of a Diverging Climate
While Edmonton faces the challenges of a summer filled with storms, Calgary’s dry conditions have led the city to issue a fire advisory due to ongoing high temperatures and dry vegetation. As the forecast suggests minimal chances of rain for Calgary, the city continues to enjoy clear skies, reinforcing its image as Alberta’s “Blue Sky City.”
Conversely, Edmonton’s summer has become a test for festival organisers and event planners, who have had to adjust to the unpredictable weather. The K-Days celebrations, a highlight of the Edmonton summer calendar, experienced cancellations due to the adverse conditions, showcasing the far-reaching implications of this weather disparity.
Why it Matters
The contrasting weather patterns between Calgary and Edmonton this summer serve as a reminder of the complex dynamics of climate in Western Canada. As extreme weather events become more frequent and intense, the implications for urban planning, disaster preparedness, and community resilience are significant. This summer’s stark division not only adds a new dimension to the rivalry between Alberta’s two largest cities but also raises questions about the region’s future as climate variability continues to unfold.
