Mobile Applications

For mobile apps developers

You can receive any weather data for your application by using JSON / XML API. Lots of applications for Android and iOS use OpenWeatherMap as weather data source. By the way the data can be received from WMS server and can be embedded into any cartographic web-application.

For web developers

If you use some cartographic services in your web-sites now you can easily add weather information to it. By the way the Drupal and other CMS plug-ins are available. We can offer you libraries for OpenStreetMaps, Google and Yandex maps. We support integration with libraries for OpenLayers and Leaflet.


Do you have a weather station?

If you have a weather station you can connect it to OpenWeatherMap service. You will get a convenient interface for gathering and monitoring data from your weather station. And you can embed the weather station data into your home page.


We are open for partnership

OpenWeatherMap is startup that offers free current weather data, forecasts and history data to the developers of web-services and mobile applications. We are seeking for investments to develop the OpenWeatherMap project in direction of data base increasing, new services development, and math algorithm enforcement.
