Where does CTV Calgary get its weather data?
CTV Calgary, like most Canadian broadcasters, sources its forecasts from Environment and Climate Change Canada (ECCC). The live forecast above uses the same official data, so you can rely on it for consistency with what you see on CTV News Calgary. For a longer look, the Calgary weather 14 day forecast on our hub uses ECCC’s extended models.
How accurate is the weather in Calgary 10 days out?
ECCC’s 10-day forecast has moderate reliability for trends (e.g., warm vs. cold), but day-to-day specifics often shift after day 5. Check the live forecast above daily for the most reliable short-term view.
What should I do if I see a severe weather alert?
Follow instructions from local authorities and check the breaking news Calgary feed on CTV News for live updates. The live forecast above will also show the alert, but always prioritize official ECCC warnings.
Does the weather in Calgary tomorrow differ from the 14-day forecast?
Yes. The “tomorrow” forecast is updated hourly and is far more precise than the 14-day outlook, which gives a general pattern. Always use the live forecast above for your immediate 24-hour plans.
