As the hockey season takes its customary summer break, the long-standing rivalry between Alberta’s two largest cities, Edmonton and Calgary, has taken an unexpected turn—this time, it’s a battle of the elements. While Edmonton grapples with unprecedented rainfall, Calgary is experiencing an unusually dry and warm spell, showcasing the stark weather contrasts that define this summer.
Record-Breaking Rainfall in Edmonton
Environment Canada meteorologist Brian Proctor revealed some staggering statistics last Friday. Edmonton has accumulated a remarkable 533.8 millimetres of precipitation during the months of June and July, setting a new record for the summer season. This figure eclipses the previous record of 417.1 millimetres, which was established in 1953. “Just an amazing amount of moisture,” Proctor stated, underscoring the sheer volume of rain that has fallen on the city.
July alone witnessed a deluge of 264.7 millimetres, resulting in flooded streets and basements, uprooted trees, and the cancellation of numerous outdoor events. The ramifications have been extensive, with the City of Edmonton estimating that storm cleanup costs could reach between £20 million and £30 million. The adverse weather has especially impacted the city’s summer festivals, including the beloved K-Days, where two major concerts had to be scrapped due to the relentless storms.
Calgary’s Dry Spell
In stark contrast, Calgary recorded a mere 10.4 millimetres of rain in July, leading Proctor to describe the conditions as “really dry.” The city experienced a modest 108.1 millimetres of precipitation in June, with approximately 75 per cent of that total coming from just two significant weather events. Since then, the lack of moisture has left Calgary devoid of thunderstorms and rain.
With the arrival of August, the forecast suggests that this trend will persist. While Edmonton continues to contend with rain, Calgary is set to bask in sunny weather with temperatures soaring into the low 30s. Environment Canada has even issued a heat warning for the region, as the city remains dry and warm, with only a slight chance of rain on the horizon.
Consequences of Extreme Weather
The disparity between the two cities extends beyond mere inconvenience. In Edmonton, the relentless storms have generated a cycle of precipitation, with each storm feeding into the next. Proctor noted that the abundance of moisture has been akin to “gasoline” for thunderstorm activity, leading to frequent severe weather events. Thunderstorms have repeatedly tracked over the city, causing localized flooding and other weather-related disruptions.
Conversely, Calgary’s dry conditions have prompted officials to issue a fire advisory due to ongoing high temperatures and the risk of wildfires. The city’s reputation as Alberta’s “Blue Sky City” is well-earned this summer, with residents enjoying clear skies while their counterparts in Edmonton contend with the fallout from a summer marked by extreme weather.
Looking Ahead: Forecasts for August
As August unfolds, meteorological forecasts predict little change in the weather patterns. Edmonton is expected to remain wet, while Calgary is likely to continue enjoying dry and sunny days. Proctor remarked that the forecast for Edmonton on August 1 includes a mix of sun and clouds, with a 30 per cent chance of afternoon showers, while the weekend will see more cloudy conditions with a 60 per cent likelihood of rain.
Meanwhile, Calgary can expect continued sunshine, with temperatures reaching around 10 degrees Celsius above the seasonal average. The lack of rain and high temperatures has raised concerns among residents and officials alike, as the city navigates the challenges posed by dry conditions.
Why it Matters
The contrasting weather experiences of Edmonton and Calgary this summer highlight the broader implications of climate variability in Alberta. As cities grapple with extreme weather events, the challenges of managing infrastructure, public safety, and environmental impacts become increasingly pronounced. This summer serves as a reminder of the need for adaptive strategies to address the consequences of climate change, ensuring that communities are prepared for the unpredictability of future weather patterns. The rivalry between these two cities may be playful, but the realities of shifting climates demand serious attention.
