🌤️ Weather Forecast API

Streamline your development workflow and bypass restrictive commercial rate limits with this zero-configuration weather API scraper. Built to tap directly into the Open-Meteo ecosystem, this fetcher lets developers extract granular, highly accurate weather data for any global coordinates without the headache of managing expensive API keys or complex authentication tokens. Just input your target latitude and longitude to scrape exact current conditions, detailed hourly meteorological shifts, and extended 16-day daily forecasts from the web. Developers building smart home integrations, travel planning websites, or custom forecasting dashboards can schedule routine runs to maintain an up-to-date feed of critical environmental variables. The scraper meticulously extracts a comprehensive suite of data points, yielding details such as surface temperature, relative humidity, wind speed and direction, total cloud cover, UV index, and precipitation accumulation. You can run the tool to gather raw data from multiple geographic points in a single execution, making it incredibly easy to map out regional weather patterns. Because this fetcher enforces no strict rate limits, you have the freedom to scale seamlessly. Integrate the scraped results directly into your backend architecture to ensure your applications remain reliably informed.

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.
