As the hockey season takes a break, Alberta’s two largest cities are engaged in an unexpected rivalry, this time driven by their wildly differing summer weather patterns. While Edmonton grapples with record rainfall, Calgary enjoys a parched summer, leading to a stark contrast that has sparked both concern and camaraderie among Albertans.
Edmonton’s Record Rainfall
Edmonton has experienced a remarkable summer in terms of precipitation, with a staggering 533.8 millimetres recorded from June through July, surpassing the previous record of 417.1 millimetres set in 1953. Environment Canada meteorologist Brian Proctor remarked, “Just an amazing amount of moisture.” The month of July alone accounted for 264.7 millimetres, resulting in flooded streets, waterlogged basements, and the cancellation of several outdoor events, including two headline concerts at K-Days, Edmonton’s beloved summer festival.
The aftermath of the relentless storms has left the city with a hefty cleanup bill, estimated between CAD 20 million and CAD 30 million. The series of storms has not only disrupted daily life but has also challenged event organisers who struggle to adapt to the mercurial weather.
Calgary’s Dry Spell
In contrast, Calgary’s July has been notably dry, with only 10.4 millimetres of rain recorded. Proctor described the situation succinctly: “Really dry is probably the best way I can word it.” The city did experience some rainfall in June, amounting to 108.1 millimetres, but much of that fell during just two significant events, leaving the city parched as July unfolded. Proctor noted that since the start of July, conditions have been too dry for thunderstorms to develop, resulting in a weather pattern that has left Calgarians basking in warm, sunny days.
As the first week of August approaches, Calgary is currently enjoying temperatures in the low 30s, prompting Environment Canada to issue a heat warning. The forecast suggests that this dry spell will persist, with no significant rainfall anticipated in the immediate future.
The Impact of Weather Patterns
The storms affecting Edmonton have been particularly severe, characterised by repeated bouts of thunder and rain. Proctor explained, “Moisture is like gasoline for thunderstorms.” The abundance of moisture in the atmosphere has allowed storm systems to develop and track over the same areas repeatedly, leading to localized flooding. Each storm event has fed the next, resulting in an almost continuous barrage of rain.
Conversely, Calgary’s weather offers a stark contrast, with the city being officially designated as “Blue Sky City.” As outdoor activities flourish under sunny skies, the Calgary Fire Department has had to issue a fire advisory due to the combination of high temperatures and dry conditions. While the city basks in warmth, it also remains vigilant against the risks posed by potential wildfires.
Looking Ahead
The outlook for August indicates that Edmonton will continue to experience wet conditions, while Calgary remains dry, a situation that has become emblematic of the summer’s unusual weather patterns. In Edmonton, the forecast calls for mixed sun and clouds with a chance of showers, while Calgary’s weather remains predominantly sunny, accentuating the climatic divide.
As both cities navigate their unique weather challenges, the rivalry takes on a playful tone, with residents from each city exchanging good-natured ribbing over their respective summer experiences.
Why it Matters
The contrasting weather patterns in Calgary and Edmonton serve as a reminder of the unpredictability of climate and its direct impact on communities. The stark differences not only affect local events and economies but also highlight broader environmental issues, including climate change and its influence on weather extremes. As Alberta grapples with these challenges, the need for sustainable solutions and preparedness strategies becomes ever more crucial for both urban centres.
