Calgary’s weather is defined by rapid shifts, strong chinook winds, and a semi‑arid climate that brings dry conditions much of the year. The live forecast above shows today’s conditions; expect daytime highs near seasonal averages and overnight lows that can drop sharply.
What is Calgary’s typical weather pattern?
Calgary sits in the rain shadow of the Rocky Mountains, which means it receives less precipitation than most Canadian cities. Winters are cold but punctuated by chinook winds that can raise temperatures by 10–20°C within hours. Summers are warm and sunny, though thunderstorms and hail are common.

Does Calgary really get chinook winds every winter?
Yes, chinooks are a regular feature from November to February. They bring warm, dry air from the Rockies, often melting snow quickly. Some winters see more chinooks than others, but few winter weeks pass without at least one chinook event.
How accurate are Calgary’s week‑ahead forecasts?
Environment and Climate Change Canada’s seven‑day outlook is reliable for temperature trends but can miss sudden chinook‑driven shifts. For shorter periods, the calgary weather hourly update above gives the most accurate near‑term picture.
