Is The Weather Network accurate?
Canada's dominant weather brand, on TV, web and mobile.
The Weather Network does not publish exactly how its forecast is made, so its accuracy cannot be independently verified. What we can grade is the open models: the Env. Canada model scored 86/100 in our test for Canada. Watching those models is the honest way to judge it.
How The Weather Network makes its forecast. The Weather Network does not publish which models or data its forecast is built from, so its exact numbers cannot be checked independently. That matters, because it means no one outside The Weather Network can check its forecast against the recorded weather the way we check the open models.
Our verdict. What we can verify is how the open models did in Canada, including Environment Canada's own GEM model, from the agency behind the WeatherCAN app and weather.gc.ca. See the Canadian scoreboard on this page.
Which forecast is most accurate in Canada?
CheckWeather Score, graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy, each measured against ERA5 (the recorded weather) over the last 30 days across 1320 cities. Lower error means a higher score. Apple Weather lists ECMWF and the US National Weather Service/NOAA among its data sources. What each big weather app says about its forecast.
