Glancing at the live forecast above is the quickest way to plan your day in Calgary, but the bigger picture matters too: the city’s high-altitude, chinook-prone climate means weather can swing by 15–20°C in hours, so check the current conditions and then read on for what to expect today and this week.
What makes Calgary’s weather so changeable?
Calgary sits near the foothills of the Rocky Mountains at about 1,045 metres above sea level. This elevation gives it a semi-arid, high-plains climate with low humidity and plenty of sunshine. The biggest wildcard is the chinook—a warm, dry wind that can raise temperatures by 20°C in a single afternoon, often melting snow within hours. In winter, a day that starts at -20°C can feel like +5°C by mid-afternoon if a chinook arrives. Summertime is typically short and warm, with July highs averaging 23°C, but thunderstorms and hail can develop quickly due to the nearby mountains.
What’s the typical seasonal range in Celsius?
January is Calgary’s coldest month, with average daily highs near -1°C and lows around -13°C. July is warmest, with highs near 23°C and lows around 10°C. Over a full year, the city receives about 335 millimetres of precipitation, with May and June being the wettest months. Snow can fall any month except July, but deep accumulations are rare thanks to chinooks.
Short-term outlook: hourly and tomorrow
For the next few hours, refer to the live forecast above for calgary weather hourly details. Tomorrow’s conditions can shift rapidly if a chinook sets in or a cold front arrives. For the remainder of the week, check calgary weather 14 day forecasts from Environment and Climate Change Canada—they remain the most reliable source for this region. The calgary weather radar (also available through the federal service) is especially useful for tracking fast-moving summer storms or winter snow bands.
How reliable are 30-day forecasts for Calgary?
Long-range outlooks (calgary weather next 30 days or calgary weather monthly) offer only broad trends. Because chinooks and Arctic fronts can override seasonal patterns, precise temperature guesses beyond a week are unreliable. Stick to 7-day outlooks for planning.
What is the best source for calgary weather radar?
Environment and Climate Change Canada provides the official radar loop for Calgary, updated every 10 minutes. It shows precipitation intensity and movement, which is key for avoiding sudden thunderstorms or tracking snowfall bands.
How does Calgary’s weather compare to Edmonton’s?
Edmonton is about 300 kilometres north and slightly cooler year-round, with fewer chinooks. Calgary tends to be a few degrees warmer in winter due to chinook influence, but both cities share the same high-plains, low-humidity climate pattern.
