As Alberta’s summer unfolds, an unusual rivalry has emerged between Calgary and Edmonton, stemming from their drastically different weather conditions. While the southern city enjoys a sun-drenched climate, its northern counterpart is grappling with unprecedented rainfall that has set new records. This stark contrast highlights the diverse climatic challenges faced by Western Canadian cities, raising questions about environmental resilience and municipal preparedness.
Record-Breaking Rainfall in Edmonton
This summer, Edmonton has experienced a deluge, with Environment Canada reporting a staggering 533.8 millimetres of precipitation between June and July. This figure surpasses the previous record of 417.1 millimetres, established in 1953, making it the wettest summer on record when considering the June to August period. Brian Proctor, a meteorologist with Environment Canada, remarked, “Just an amazing amount of moisture,” indicating the sheer volume that has fallen in such a short time.
July alone brought 264.7 millimetres of rain, resulting in flooded streets, damaged properties, and the cancellation of numerous outdoor events, including celebrations for the annual K-Days festival. The City of Edmonton anticipates that the financial implications of storm cleanup efforts could reach between £20 million and £30 million.
Calgary’s Dry Spell
In stark contrast, Calgary has been basking in dry conditions, collecting only 10.4 millimetres of rain in July. Proctor described the situation as “really dry,” noting that the bulk of the city’s June rainfall—108.1 millimetres—occurred during just two significant weather events. Since then, the region has seen little precipitation, limiting the development of thunderstorms that are typically welcomed during the summer months.
As August approaches, the forecast suggests that Calgary will continue to enjoy warm, sunny weather, with temperatures reaching the low 30s. This persistent dryness has led to a fire advisory being issued, as the city grapples with ongoing high temperatures and the potential for increased wildfire risks.
The Storm Cycle in Edmonton
The storms that have battered Edmonton this summer have not only been relentless but have also contributed to a cycle of severe weather. Proctor explained that each storm event has effectively fed into the next, creating a situation where the atmospheric conditions are ripe for thunderstorm activity. He likened the moisture available to “gasoline,” fueling the development of these intense weather systems. This has resulted in repeated storms tracking over the same areas, causing significant and localized flooding.
The city has experienced extreme downpours, with some areas receiving higher concentrations of rainfall than others. Proctor noted, “It’s really been very, very convective and extreme downpours,” underscoring the chaotic nature of this summer’s weather.
Looking Ahead: Contrasting Forecasts
As we move into August, the divergent weather patterns are expected to persist. Calgary’s forecast remains predominantly dry, while Edmonton is set to continue experiencing significant rainfall. The first day of August is predicted to bring a mix of sun and clouds for Edmonton, with a 30 per cent chance of afternoon showers. Conversely, Calgary is projected to enjoy clear skies and soaring temperatures, further enhancing its reputation as Alberta’s “Blue Sky City.”
The ongoing weather rivalry between these two cities not only serves as a topic of friendly banter among residents but also poses substantial implications for local infrastructure, emergency services, and environmental management.
Why it Matters
The contrasting weather patterns faced by Calgary and Edmonton this summer serve as a poignant reminder of the broader environmental shifts affecting Western Canada. As cities grapple with the effects of extreme weather, understanding and adapting to these changes is crucial for ensuring community resilience. The stark differences in rainfall and temperature underscore the need for comprehensive planning and preparedness strategies that can mitigate the impacts of such climatic extremes, ultimately safeguarding both urban environments and the well-being of their residents.
