Open-Meteo utilizes open-data weather forecasts provided by national weather services. These services offer numerical weather predictions that are free to download. However, working with these models can be challenging, as it requires expertise in binary file formats, grid-systems, projections, and the fundamentals of weather predictions.
Like many other weather APIs, Open-Meteo integrates high-resolution local and global weather models. Over 2 TB of data are downloaded and processed daily from multiple national weather services. The collected data is then stored in local files using a customized file format and compression technique to enhance access to time-series data such as a 14-day temperature forecast.
In contrast to other weather APIs, Open-Meteo provides complete access to its source code, and all data sources are openly listed, crediting the national weather services for their work. With Docker or prebuilt Ubuntu packages, it is possible to launch your own weather API within minutes. By providing the source code, users can conduct detailed verifications of the weather data processing and even make modifications themselves. Contributions are highly encouraged and welcomed.
The API is available for non-commercial use at no cost. Despite being free of charge, the forecast accuracy is top-notch. The API utilizes a vast array of local weather models with rapid updates, ensuring that the most precise forecast is generated for any location globally.

The latest iteration of the Open-Meteo weather API has been released! In recent weeks, we've implemented a series of minor enhancements aimed at bolstering accuracy, dependability, and overall performance.
One particularly noteworthy upgrade is the incorporation of 15-minute data derived from the German DWD ICON-D2 and NOAA HRRR models, substantially enhancing the precision of short-term forecasts. Further details on this can be found in our blog post.
We extend our gratitude for your ongoing support and trust that you will find great value in the latest enhancements introduced within the Open-Meteo weather API!

About the Open-Meteo Weather API: Open-Meteo is a weather API that operates on an open-source basis and provides free access for non-commercial purposes. No API key is necessary; you can start using it right away!
At Open-Meteo, we firmly believe that access to accurate and dependable weather data should be accessible to all. That's why we've developed an open-source weather API that utilizes weather forecasts derived from open-data sources offered by national weather services. Unlike other weather APIs, Open-Meteo grants complete access to its source code, and all data sources are openly acknowledged, giving credit to the national weather services for their valuable contributions. Users can set up their own weather API rapidly using Docker or prebuilt Ubuntu packages. By sharing the source code, users can thoroughly scrutinize the weather data processing and even make adjustments as needed. We actively encourage and welcome contributions from our user community.
This API is freely available for non-commercial use, with no associated costs. Despite being free of charge, it delivers top-tier forecast accuracy. Leveraging an extensive range of local weather models with frequent updates, the API ensures the generation of highly precise forecasts for locations worldwide.
