According to consistent records from Environment and Climate Change Canada and Current Results, Calgary’s total annual precipitation (rain plus snowmelt equivalent) over the last ten years (2015–2024) has varied notably, reflecting the city’s highly continental and semi-arid prairie climate.
Calgary recorded approximately 548 millimetres of total precipitation in 2024, a figure that is considerably higher than its long-term average of about 418 to 445 mm per year. This total includes both rainfall and the water equivalent of snowfall

Observations
-
Roughly 70–80 % of Calgary’s annual precipitation occurs between May and September, dominated by convective thunderstorms and frontal rains.climate
-
The city typically receives 110 rain or snow days per year, far fewer than coastal regions like Vancouver.currentresults
-
The sharp decline in 2024 aligns with Alberta’s widespread drought pattern, while 2020 and 2019 were unusually moist years, influenced by persistent storm tracks and high soil moisture recharge.extremeweatherwatch
In summary, Calgary’s precipitation over the past decade shows wide interannual variability but averages near its long-term norm, consistent with the city’s semi-arid prairie climate punctuated by occasional very wet and very dry years.
