Conditions of use

Free version

Windy API is free and with unrestricted traffic usage, but offers only the gfs forecast model and only wind,rain,clouds, temperature, pressure,currents and waves layer. The Windy logo MUST remain as it is, i.e. clickable and without modification. However, you can move the Windy logo wherever you want within the Windy map. For the free version of the API, we reserve the right to 1) display advertisement inside the Windy map, 2) place "Download Windy App" message from time to time on mobile devices, or 3) discontinue free version of Windy API v4 at any time without prior notice

Paid version

For serious work, we recommend to use the paid version that contains iconEu, nam and gfs models and the most of all layers and also isolines. Paid version will also not contain our advertisement. It costs only 720USD per year (ordered via this form and paid annually via invoice). Developers of paid version can decrease opacity of Windy logo to 0.8 (however logo must remain clickable) and usage limit is average of 5.000 Unique Visitors a day (measured by Google Analytics). For permission to a higher quota, please contact us.

We are not allowed to provide ECMWF data to third parties, and therefore we cannot provide layers based on this data model (thunder, deg0, cloudtop, cbase, visibility, swell3, snowcover, ozone, sst and cape). Please note that some layers are based on multiple forecast models. Such layers are available, however, without ECMWF forecasts (for example: waves, wind waves or swell where the Wavewatch 3 model does not cover the Mediterranean Sea and other areas). We also cannot provide you with the radar layer. Everything else is included in the paid version. Please check the map for yourself at and see if it meets your expectations.

Non-commercial projects

Interesting and non-commercial sites using Windy API can ask for free upgrade to the paid version. The condition is that your project will be open sourced on GitHub. If this is your case, use the same form for paid version and describe your request.
