Uncovering the Truth: Is Calgary Colder than Edmonton?

The age-old debate between Calgary and Edmonton, two of Alberta’s largest cities, has sparked a lot of discussion among Canadians. One of the most common topics of conversation is the weather, specifically which city is colder. In this article, we will delve into the world of temperature trends, climate patterns, and weather phenomena to determine if Calgary is indeed colder than Edmonton.

Introduction to Calgary and Edmonton’s Climate

Calgary and Edmonton are both located in the province of Alberta, Canada, but they have distinct climate profiles. Calgary is situated in the southwestern part of the province, near the Rocky Mountains, while Edmonton is located in the central part of Alberta, in the heart of the Canadian Prairies. These geographical differences contribute to the unique climate characteristics of each city.

Calgary’s Climate

Calgary’s climate is classified as a humid continental climate, with cold winters and mild summers. The city’s proximity to the Rocky Mountains creates a rain shadow effect, resulting in lower precipitation levels compared to other parts of Canada. Calgary’s temperature ranges from an average high of 23°C (73°F) in July to an average low of -12°C (10°F) in January. The city experiences a significant amount of sunshine throughout the year, with an average of 2,396 hours of sunshine per year.

Edmonton’s Climate

Edmonton’s climate is also classified as a humid continental climate, but with a slightly different profile. The city’s location in the Canadian Prairies means it experiences a more continental climate, with larger diurnal temperature ranges. Edmonton’s temperature ranges from an average high of 23°C (73°F) in July to an average low of -14°C (7°F) in January. The city receives an average of 2, Guild hours of sunshine per year, slightly less than Calgary.

Temperature Comparison

To determine which city is colder, we need to examine the temperature data for both Calgary and Edmonton. According to Environment and Climate Change Canada, the average temperature in Calgary from 1981 to 2010 was 3.8°C (38.8°F), while in Edmonton it was 2.7°C (36.9°F). This suggests that Edmonton is, on average, colder than Calgary.

However, it’s essential to look at the monthly temperature averages to get a more detailed understanding of the temperature patterns in both cities.

As shown in the table, Edmonton’s average temperature is lower than Calgary’s in most months, indicating that Edmonton is indeed colder. However, it’s crucial to note that temperature is just one aspect of a city’s climate, and other factors like precipitation, sunshine, and wind chill should also be considered.

Wind Chill and Humidity

Wind chill and humidity are essential factors to consider when evaluating the coldness of a city. Wind chill is the perceived decrease in temperature caused by wind, while humidity refers to the amount of moisture in the air. Both factors can significantly impact how cold a city feels.

Calgary’s proximity to the Rocky Mountains creates a unique wind pattern, with chinook winds bringing warm air from the Pacific Ocean. These winds can significantly raise the temperature in Calgary, making it feel warmer than the actual temperature. In contrast, Edmonton’s location in the Canadian Prairies means it experiences a more consistent wind pattern, with winds coming from the north and northwest.

In terms of humidity, Calgary’s climate is generally drier than Edmonton’s, with an average relative humidity of 54% compared to Edmonton’s 61%. This means that Calgary’s air tends to feel drier and colder, while Edmonton’s air feels more humid and colder.

Impact of Wind Chill and Humidity

The combination of wind chill and humidity can make a city feel significantly colder than the actual temperature. For example, if the temperature is -10°C (14°F) with a wind chill of -15°C (5°F) and high humidity, it will feel much colder than a temperature of -10°C (14°F) with low humidity and no wind chill.

In Calgary, the chinook winds can raise the temperature by up to 10°C (18°F) in a matter of hours, making the city feel significantly warmer. However, when the winds are not blowing, Calgary’s temperature can drop rapidly, making it feel colder.

In Edmonton, the consistent wind pattern and higher humidity levels can make the city feel colder than the actual temperature. The wind chill effect is more pronounced in Edmonton, with winds making the temperature feel up to 5°C (9°F) colder than the actual temperature.

Conclusion

In conclusion, while both Calgary and Edmonton experience cold winters, the data suggests that Edmonton is, on average, colder than Calgary. However, it’s essential to consider other factors like wind chill, humidity, and sunshine when evaluating the coldness of a city.

Calgary’s unique wind pattern, created by the Rocky Mountains, can make the city feel warmer than the actual temperature, while Edmonton’s consistent wind pattern and higher humidity levels can make it feel colder. Ultimately, the perception of coldness is subjective and depends on individual tolerance and preferences.

As we’ve seen, the temperature comparison between Calgary and Edmonton is not a simple one. Both cities have their unique climate characteristics, and it’s crucial to consider multiple factors when determining which city is colder. Whether you prefer the warmer, sunnier climate of Calgary or the colder, more humid climate of Edmonton, both cities have their charms and attractions.
