FAQs

Is an API key required? No. Open-Meteo is free for non-commercial use with no registration required.

How far back does historical data go? Historical data is available from 1940 onward for most locations.

How accurate is the forecast? Open-Meteo uses multiple global weather models (ECMWF, GFS, etc.) and is highly accurate, especially for the first 7 days.

Can I get hourly data? Yes — set hourlyVars to include variables like temperature_2m, windspeed_10m, etc.

Why is marine data not available for my location? Marine data requires coordinates in or near ocean/coastal areas. Inland coordinates will return an error.

What timezones are supported? Any IANA timezone string (e.g. Europe/Berlin, America/New_York). Use auto to detect from coordinates automatically.
