The weather map: all three models at once
Env. Canada, European, American side by side across Canada.Live rain radar →What's the weather doing across Canada today? Environment Canada's GEM, the European and the American models each have their own take on our winters and summers. We compare all three for any Canadian town, so you know when to trust the forecast and when to pack a backup plan for the cold snap.
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 1304 cities. Lower error means a higher score. The apps you know (AccuWeather, Apple Weather, The Weather Channel) are built on these models.
Popular weather apps — and what powers them
Real app-store ratings, plus the forecast each one runs on
App-store stars measure the app experience (design, features, reliability) — not forecast accuracy. For accuracy, see the model scoreboard above. Ratings from the US & UK App Store and Google Play, July 2026; they drift over time. Apple Weather is built into iOS, with no separate store rating.
The forecasts Canadians check
Environment Canada runs the national GEM model as open data, so it sits right in the comparison above. The Weather Network and AccuWeather keep theirs closed, so we link you to them.
Every forecast runs on a model. We show you three, side by side.
When the Env. Canada, European and American models agree, the forecast is solid. When they split, sometimes by 8° on the same afternoon, it's genuinely uncertain, and no single app will tell you that. We turn that disagreement into a plain-English confidence score.

Three models, one view. Where they disagree, you know to take the forecast with a pinch of salt.
The models the pros use
ECMWF and GFS are the two global heavyweights every forecaster starts from, plus weather.gc.ca. No black boxes.
Honest & sourced
We show real, open model data and cite it. The closed apps can't show theirs, which is why AI assistants can cite us, not them.
