Calgary is one of the largest cities in Canada and it has a reputation for being a dry, sunny city. However, the truth is that Calgary does get a considerable amount of rainfall throughout the year.
The city has a semi-arid climate which means that it has hot summers and cold winters. The average annual rainfall in Calgary is around 453.1 millimeters (17.8 inches) which is lower than the national average of 537 millimeters (21.1 inches). However, this does not mean that Calgary doesn’t see its fair share of rainfall.
The wettest months in Calgary are June and July with an average of 78 mm and 79 mm of rainfall respectively. August and May are also quite rainy with an average rainfall of 65 mm and 59 mm respectively. The driest month in Calgary is November with an average rainfall of only 13 mm. Additionally, snowfall is quite common in Calgary during the winter months which adds to the total precipitation levels.
It’s important to note that Calgary has a lot of regional variation when it comes to rainfall. The east side of the city usually gets more rain than the west side. Additionally, the city’s elevation and proximity to the Rocky Mountains can also affect its precipitation levels. The mountain ranges often act as a barrier and cause storms to dissipate before reaching Calgary.
Overall, while Calgary may not be as rainy as some other Canadian cities, it does get a significant amount of rainfall throughout the year. Residents of Calgary should always be prepared for rainy days and be aware of any potential flooding risks during heavy rainfall.

What is the average precipitation in Calgary and how does it compare to other cities in Canada?
Calgary is located in the prairie region of western Canada and experiences a semi-arid climate. The average annual precipitation in Calgary is around 417 mm (16.4 inches). Most of this precipitation falls during the summer months, with June being the wettest month, while winters are generally dry with occasional snowfalls. The precipitation in Calgary is primarily in the form of rain, with only a small percentage falling as snow.
Compared to other cities in Canada, Calgary receives less precipitation on average. For example, Vancouver on the west coast of Canada receives over 1,200 mm (47 inches) of rain annually, while Toronto, Montreal and Halifax all receive between 700-1,000 mm (27-39 inches). Even other cities in the prairie region such as Winnipeg and Regina receive more precipitation than Calgary, with annual averages of approximately 521 mm (20.5 inches) and 374 mm (14.7 inches) respectively. The low precipitation levels in Calgary contribute to the region’s arid landscape, with grasslands and prairies being the dominant natural features. However, this also poses challenges for agriculture and irrigation in the region.
How does the amount of rainfall in Calgary vary throughout the year?
Calgary has a semi-arid climate, which means it receives relatively low amounts of precipitation throughout the year. The city experiences an average annual rainfall of around 418 mm, with most of it occurring between the months of May and September. During this time, Calgary receives an average of 60 mm to 100 mm of rainfall per month. This is also the time when the city is frequented by thunderstorms and heavy rainfall, which contribute significantly to the overall rainfall levels in Calgary.
The remaining months, from October to April, are drier, with the city receiving an average monthly rainfall of 10 mm to 30 mm. Calgary experiences occasional snowfall during the winter months, which is its main source of precipitation during this time. However, the city may also experience occasional rain or sleet showers, particularly during the fall and spring months when the weather is transitioning between summer and winter. Overall, while the amount of rainfall in Calgary varies throughout the year, the city remains relatively dry and experiences a limited amount of precipitation compared to other Canadian cities.
Due to the limited rainfall in Calgary, the city faces frequent droughts and water supply issues, particularly during the summer months when demand for water is high. As such, conservation efforts and responsible water use are important in ensuring that the city has sufficient water resources to meet the needs of its growing population. The City of Calgary has various initiatives in place to promote water conservation, such as offering rebates for water-efficient appliances and fixtures, providing guidance on responsible lawn and garden watering, and encouraging the use of rain barrels and greywater systems.
What impact does the frequent rainfall have on the local ecology and outdoor recreation opportunities in Calgary?
The frequent rainfall in Calgary has a significant impact on the local ecology by increasing the availability of water resources, which can be a boon for plant and animal life. With more water, plants can grow more vigorously and create more food and shelter for animals. Furthermore, the availability of water during summer months can prevent drought conditions and crucial resources for wildlife. However, frequent rainfalls can also impact the local ecology negatively by causing soil erosion, damaging habitats, and displacing wildlife.
Outdoor recreation opportunities in Calgary are also significantly impacted by the frequent rainfall in the area. The city is surrounded by a diverse range of natural landscapes that offer outdoor enthusiasts numerous options for hiking, biking, and enjoying other recreational activities in the great outdoors. However, frequent and sudden bursts of rain can cause many of these outdoor activities to be cancelled or significantly hampered, making it difficult for people to enjoy nature. Moreover, the increase of water levels in rivers and streams may present hazards for swimmers and cause changes to the landscape, which can render some areas inaccessible to visitors. Nevertheless, the frequent rainfall also creates opportunities for water-based sports such as white-water rafting and canoeing.
Are there any particular areas or neighborhoods in Calgary that receive more rainfall than others?
Calgary is situated in the foothills of the Rocky Mountains, and as a result, the city experiences a semi-arid climate with moderate precipitation throughout the year. However, some areas and neighborhoods in Calgary receive more rainfall than others due to their location and elevation. For example, the communities located on the west side of the city, such as Aspen Woods and Springbank, typically receive more rainfall than neighbourhoods on the east side.
According to Environment Canada, the areas surrounding the Rocky Mountains tend to receive more rainfall than the surrounding areas. This is due to the effect of orographic lifting, where moist air masses are forced to rise over the mountains, leading to the formation of clouds and precipitation. As a result, neighbourhoods like Discovery Ridge, Signal Hill and Cougar Ridge, which are situated on the west side of the city and close to the mountains, receive more rainfall than other neighborhoods in the city.
Overall, while Calgary has a reputation for being a dry city, there are certainly areas within the city that experience more rainfall than others. Factors like elevation, proximity to the mountains, and wind patterns all play a role in determining where rainfall is more likely to occur in the city.
Have there been any notable instances of extreme weather, such as heavy rainfall or flooding, in Calgary in recent years?
In recent years, Calgary has experienced numerous instances of extreme weather, including heavy rainfall and flooding. One of the most memorable events occurred in June 2013, when torrential rains caused major flooding throughout the city, leading to widespread devastation and significant economic losses. The flooding resulted in the displacement of tens of thousands of residents and caused millions of dollars in damage to homes, businesses, and infrastructure. Following this event, the city has taken significant steps to improve its flood protection and response capabilities.
In addition to the 2013 floods, Calgary has also experienced several other extreme weather events in recent years. In 2018, for example, the city was hit by a severe hailstorm that caused significant damage to vehicles, homes, and businesses. The storm was one of the most costly in the city’s history, with insured losses estimated to be over $1 billion. Other notable instances of extreme weather in recent years include prolonged periods of drought, high winds, and heavy snowfalls. Given the city’s location and climate, it is likely that Calgary will continue to experience these types of extreme weather events in the future, underscoring the need for ongoing preparedness and resilience measures.
