0.2.69 Improvements and bugfixes
12 weeks ago
The new version of the Open-Meteo weather API is now available! Over the past few weeks, we have made several small improvements to enhance accuracy, reliability, and performance.
One notable improvement is the enhanced accuracy in calculating the position of the sun, resulting in more precise forecasts of direct solar radiation on a normal pane (DNI). Additionally, sunrise and sunset times are now accurate down to the minute.
Behind the scenes, we have given a major update to the Open-Meteo API documentation. It now features a fast and user-friendly web interface built with SvelteKit. This update makes it easier for users to navigate through the wide range of weather variables and parameters.
We would like to express our gratitude to our initial customers who have subscribed to the commercial [API SaaS plan](https://open-meteo.com/en/pricing). Thanks to their support, we have deployed additional servers in Europe and North America. This expansion ensures better reliability and faster access to weather data, regardless of your location. Furthermore, it allows us to provide weather data to the general public for non-commercial use.
Thank you for your continued support, and we hope you enjoy the latest improvements in the Open-Meteo weather API!

About the [Open-Meteo Weather API](https://open-meteo.com): Open-Meteo is an open-source weather API and offers free access for non-commercial use. No API key is required. You can use it immediately!
We at Open-Meteo believe that access to accurate and reliable weather data should be available to everyone. That's why we have created an open-source weather API that utilizes open-data weather forecasts provided by national weather services. Unlike 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, users can launch their 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. We welcome and encourage contributions from our users.
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.
Thank you for considering Open-Meteo for your weather data needs. We are always striving to improve and welcome any feedback or questions you may have. Please feel free to contact us at [

0.2.48 Ensemble API
18 weeks ago
We are excited to announce the release of Version 0.2.48 of the Open-Meteo weather API, featuring the highly anticipated [Ensemble API](https://open-meteo.com/en/docs/ensemble-api). This new version introduces a powerful ensemble forecasting tool that brings together multiple weather models for enhanced accuracy and reliability.
The new [Ensemble API](https://open-meteo.com/en/docs/ensemble-api) integrates ensemble models from ECMWF, NOAA, DWD, and the Canadian weather service. With the Ensemble API, users can now access perturbed forecasts up to 35 days in advance in 1-hourly resolution.
Thank you for being a part of our growing community!
