Calgary’s weather is defined by its dramatic chinook winds, which can lift winter temperatures by 15°C or more in a matter of hours, and its reputation as one of Canada’s sunniest major cities. The live forecast above gives you today’s conditions, but Calgary’s weather demands flexibility — pack for seasons within a day.
Why does Calgary’s weather change so quickly?
Calgary sits where the prairies meet the Rocky Mountain foothills, at roughly 1,048 metres above sea level. That elevation, combined with its proximity to the mountains, creates rapid temperature swings and highly variable conditions. Chinooks are the most dramatic example: warm, dry winds that descend the eastern slopes of the Rockies, sometimes raising temperatures by 20°C in under an hour. If you’re planning ahead, checking a calgary weather 14 day forecast can give you a sense of the pattern, but shorter-term tools like calgary weather radar are often more reliable for immediate decisions. For context on how Calgary compares to other prairie cities, see our Edmonton Weather page.
What does this season’s forecast tell you?
The live forecast above reflects Calgary’s current conditions, reported in Celsius — as all Canadian weather should be. Comparing it to the city’s calgary weather monthly averages — January highs around −1°C, July highs near 23°C — helps put today in context. For detailed planning, calgary weather hourly updates are useful, and if you’re curious about the longer view, the calgary weather next 30 days outlook can help. For tomorrow’s specifics, check the calgary weather tomorrow section of the live forecast. For a broader look at conditions across the country, visit our Canada weather hub.
How often do chinooks occur in Calgary?
Calgary experiences roughly 20 to 30 chinook days each winter, most commonly between November and February. They can last from a few hours to several days and are most frequent in the city’s western neighbourhoods near the foothills.
Is Calgary the windiest city in Canada?
No — that distinction belongs to St. John’s, Newfoundland — but Calgary’s average wind speed of about 20 km/h makes it one of the windiest major prairie cities. Chinooks can bring gusts exceeding 100 km/h to exposed areas.
How much snow does Calgary get each year?
Calgary averages about 136 cm of snow annually, with most falling between October and April. The calgary weather yearly pattern sometimes includes light flurries in May, but June through September is typically snow-free.
