api.met.no/weatherapi is an interface to a selection of data produced by MET Norway. The data are available for use under a Creative Commons license. See also separate conditions for use of the service. Several people have developed third-party client libraries for various programming languages.
All regular users of the API are strongly recommended to subscribe to our API-users mailing list as this is the only channel on which we will communicate planned changes outside the API itself (see the archives for past notifications).
For operational status and maintenance notifications, see status.met.no (please bookmark in case there is a problem with the site).
Data owned by other institutions than MET Norway is not available for unrestricted public use. This is specified in the documentation of each product. Examples of such products are the Nordic radar images and some satellite images. Refer to the documentation of each product.

Some product changes, mainly of interest to Norwegian users:
This product will be terminated on July 1st, as it has been replaced by MetAlerts on the new Yr website. We are working on a new map-based service, which is currently in beta and available on skogbrannfare.met.no.
The old retro.yr.no site will link to this after July 1st. We are also working on making the raw data files avaiable on thredds.met.no as NetCDF files, more info on this later.
On June 1st we will start using a new tool for making SIG-WX charts. The images will look somewhat different and have other dimensions, but will be available on the same URL as before. We are planning to add a Nordic map later, in which case we might be bumping the version number. More info on this later.
On June 15th, we will add a "lightning" type to MetAlerts. This will only be of yellow severity, and signify events with a large amount of lightning strikes.
On June 1st, the route Korpfjell-ENKR will be removed, and the Stangnestind-ENKR route added.
As mentioned earlier, Oceanforecast 2.0 is now in production and version 0.9 has been deprecated, to be removed on 2021-07-01. Despite what we said earlier there will be no change in the XML format for 0.9, as we have extended the EOL of the backend model to the same date. (The experimental XML version in 2.0 is also going away, although later in the summer).
The Probabilityforecast product has also been deprecated and will be removed on 2021-07-01. As a replacement we have added the following new variables to complete.json in Locationforecast/2.0:
We have also improved the handling of requests outside coverage for Nowcast and Oceanforecast (2.0). Any requests outside the model area (as defined by the shapefile which can be downloaded from the /coverage endpoint) will get a 422 error response. Any requests within the model area but which we have no data for (either due to lack of radar range or ocean forecasts for dry land) will get a GeoJSON response with an appropriate error or warning message.
Note that we have implemented a "snap" functionality in Oceanforecast so land points near the coast will return the nearest point at sea (this means the coordinates in the URL and JSON may be different). The new model areas can be seen on the maps here:
Finally, as you may know we have not supported unencrypted HTTP for several years, and all requests to port 80 have been redirected to the corresponding HTTPS URL. Yet, after several years we still get a lot of traffic from old systems which has not been updated to use HTTPS, which in some cases could be considered a privacy liability. As a consequence we have decided to drop this feature; now all requests to po 80 will be redirected to the front page of the API.
