Partly cloudy,much the same tomorrow
Env. Canada, the European and the American model put Sidney's high today between 16° and 22°, a 5° split. Tomorrow looks clear around 21°, with a 5% chance of rain, and the models disagree, so treat it as uncertain.
Sidney is a small town of about 12,000 people in British Columbia, sitting at 48.6°N in a temperate climate zone. Env. Canada, European, American each forecast Sidney with their own physics, so we line all three up and flag where they disagree. Nearby towns include North Saanich, Brentwood Bay, Central Saanich.
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.
