Open-Meteo Weather Scraper

Extract weather data from Open-Meteo — a free, open-source weather API with global coverage. Get weather forecasts up to 16 days ahead, historical weather going back to 1940, air quality data, marine conditions, and city geocoding. No API key required.

What you can scrape

• Weather forecasts — up to 16 days of daily and hourly weather for any location worldwide
• Historical weather — past weather data for any date range since 1940
• Air quality — PM2.5, PM10, CO, NO2, ozone levels and European AQI index
• Marine conditions — wave heights, wave periods, swell data for coastal/ocean locations
• Geocoding — find latitude/longitude coordinates for any city worldwide

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.
