Weather Radar APIs

Radar APIs deliver precipitation imagery rather than point forecasts. RainViewer is free and keyless, serving animated radar tiles and forecast overlays from stations worldwide. National services publish their own radar: Bright Sky passes along German DWD radar as JSON, KNMI offers raw Dutch radar datasets for download, and Météo-France includes radar in its portal. GribStream adds satellite and radar data by coordinate on a freemium plan. Free Weather APIs →

Choosing a Weather Radar API

Is there a free Weather Radar API?

Yes. RainViewer, Bright Sky, KNMI and Météo-France API Portal are free to use, and GribStream has a free tier alongside paid plans. See all free Weather APIs.

Which Weather Radar APIs work without an API key?

RainViewer and Bright Sky need no key or sign-up, so you can try them with a plain request.

Can I call a Weather Radar API from front-end JavaScript?

RainViewer and Bright Sky allow cross-origin requests and need no key, so they work straight from the browser. For the others, call them from your server so your key stays private.

Can I use Weather Radar APIs in a commercial project?

Bright Sky permits commercial use. RainViewer restricts it, for example to non-commercial or attributed use, so read the terms first.

Which Weather Radar APIs work with AI agents?

GribStream has an MCP server, so an AI agent can call it directly. Bright Sky and Météo-France API Portal publish an OpenAPI spec for generating clients and tools.
