FAQ

How accurate is Open-Meteo?

Very accurate — uses major global models (ECMWF, ICON, GFS). Comparable to OpenWeatherMap.

Rate limits?

No published limits for non-commercial use. Commercial users should self-limit to ~10,000 calls/day.

Historical data?

This actor focuses on forecasts. For historical weather, use Open-Meteo's archive endpoint separately.

What's weatherCode?

WMO standard weather codes (0=clear, 1-3=cloudy, 51-67=rain, 71-77=snow, etc.).

What's the forecast accuracy?

Open-Meteo uses ECMWF and DWD models. Reliable up to 7 days, useful up to 14.

Can I get historical weather data?

Not in this actor — it focuses on forecasts. Open-Meteo has a separate historical API.
