Weather Radar Database API

Weather radar database is a dynamic JSON file that describes three main entities and their relations:

  • Weather radars
  • Weather radar images
  • Weather radar data sources

Whenever any of this data is changed in RainViewer, it will change in this database as well. To get access to the database, you need to be a Gold, Gold+, or Platinum patron on our Patreon page. We will send you a link to the database, and this link will work until you remain an active patron.

Become our patron!

If you enjoy our API and want to keep it free for as long as possible, please support us at Patreon. You will also get access to the weather radar database API, 60 minutes of weather radar nowcast map, and a possibility to get tiles in your own custom color scheme.

Database File Example

A database file consists of three root objects:

  • radars - an array of all known radars that is available under “Single Radar Mode” in RainViewer now.
  • images - an array of all images that are now trying to download (sometimes it will not happen).
  • providers - weather radar database sources.

Here is an example of the database file with one radar, one image, and one source description:
