Welcome to the MET Norway Weather API v.3
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).
For information on available data and how to access them, please refer to the weatherapi documentation. For a list of changes since version 2, see the Release Notes for v.3.
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.

NewsMore changes to Radar and Radarlightning 2019-07-02Due to increased workload by the new 5 min radar interval, we have had to reduce the number of different images available. In short, generating GIF animations from existing static GIF images continues as before. However, due to the 50% increase in images and 33% shorter production window, generating animations from PNG is no longer possible and has been terminated. We apologize for the lack of advance notice, but we had not foreseen this would be a problem. Since we know this will cause existing functionality to break, we've come up with a temporary solution where we substitute the missing animations with similar products. In most cases the pixel dimensions will be different, but this can be scaled in the browser. Also note that content=image and content=animation now will return totally different images, so be wary of using size=small for static thumbnails for the animations. reflectivity_hires and rainrate_with_phaseAll animations of type reflectivity_hires and rainrate_with_phase will be substituted with type reflectivity. Where radarsite indicates an area these will be identical, but single radars will be substituted to the closest area as per the following table:
lightningAll requests for lightning animations (including the Radarlightning product) now return the "norway" image. All other animations have been terminated. We have some images currently used internally which could be substituted for each individual area, but they are currently not available on the API. We will be working on a possible replacement later this summer. "medium" and "large" size static imagesThe little used "medium" and "large" sizes have been terminated. All requests for these sizes now return the "normal" image. If you scale this in the browser it should not be noticable to the end users. This does not affect radarlightning which already uses only "normal" size. Also, the small GIF animations haven't been produced for a long time and will be removed from the API. This means only the following variations will be available in the future:
Again, we're sorry for the inconvenience, but hopefully the faster radar scan rate should compensate for the reduced size options. Future changesIn closing, we will like to inform you that later this year we'll be releasing a new beta version of the Radar service, with a coherent set of areas and types which should be much more understandable than the current mess. Also, GIF animations will be replaced by Javascript, which should be much more user-friendly as you can then pause or jump forwards and backwards in time to see details. We strongly suggest you consider dropping GIF animation as soon as possible, since now that most partners are using Javascript or WMS we plan to phase out GIF completely by the end of 2019. Changes to Radar, Nowcast and other products 2019-06-07RadarFrom Wednesday June 12th, the radar images will be produced every 5 mins. New features
End-of-lifeSpotwind 1.0 has been replaced by 1.1 which delivers data for 24 hours instead of 6. Version 1.0 will expire 2019-09-02. ExtremesWWC is expected to be removed some time in the near future, to be replaced with a similar feature in our Frost API for observations. We will come back with further news when this is available. Textforecast 1.6 has been deprecated, and the land and sea forecasts have been re-implemented in 2.0 with a new, cleaner XML format which can now be validated. The aviation forecasts have been moved to a new product "aviationforecast" but remains otherwise unchanged. Since the migration is now complete we will terminate version 1.6 on 2019-09-02. Change log
