Canada, European, American each forecast Beauharnois with their own physics, so we line all three up and flag where they disagree.

We grade every model against the weather that actually happened, so you can see which forecast model is most accurate in Canada before you trust any single number.

The CheckWeather Score blends temperature, wind and rain accuracy — each measured against ERA5 (the recorded weather) over the last 30 days across 1302 cities. Lower error means a higher score. See which forecast model is most accurate in Canada, how we measure forecast accuracy, or which model each weather app uses.

The models often agree on temperature and still split on rain — and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.
