🌎 About Open-Meteo Historical Weather Data

Open-Meteo provides high-quality historical weather data using a combination of global and regional weather models.

For Canada and North America, it mainly relies on:

✅ GEM (Global Environmental Multiscale Model) — from Environment and Climate Change Canada (ECCC), Canada’s national weather model, approx. 2.5–10 km spatial resolution.
✅ GFS (Global Forecast System) — from NOAA (U.S.), ~13 km global resolution.
✅ ICON — from the German Weather Service (DWD), ~13 km global resolution.

Open-Meteo automatically selects the best available model with the finest resolution for the location and time range you request.

🔍 Estimated data precision for historical/recent records:

Wind speed: ±1–2 m/s (±3–7 km/h)
Wind direction: ±10–30 degrees
Temperature: ±1–2°C

For Canada, you can generally expect historical data at ~2.5–10 km grid resolution, based on Environment Canada’s GEM-HRDPS or GEM-Regional where available.
