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.
New version of Routeforecast 2022-06-30
Due to changed requirements the horizontal maps will be discontinued on Sept 1st. The only product still available after that date will be the vertical cross sections (vcross).
Since this is a breaking change and lots of stuff in the interface and documentation suddenly becoming redundant, we have decided to make a new version 2.0 with only the vcross images as can be found here:
Version 1.0 is now deprecated, and will be removed on 2022-09-01.
From our logs there were hardly anyone using the horizontal maps, but users of the vcross images must now update their URLs to the new format:
(Also note that the new version is stricter about identification than before, so if you haven't already set a User-Agent header with contact information this is a good time to do so.)
Changes to MetAlerts and NLAroutes 2022-05-22
From 1 June 2022 there will be some changes in the CAP warnings in MetAlerts:
Some of the area polygons will now be drawn freehand by the meteorologists, and will be in better agreement with the actual weather situation. We will still use geocode "county" and "municipalityId" for the affected administrative areas, but geocodes NUTS3 and iso will no longer be included in the CAP file.
We suggest that users of CAP warnings make some extra checks after 1 June to ensure their systems are running as intended. If you should find any discrepancies, please contact us.
Next week, the number of available routes will increase from 27 to 86. Also, the time period covered will decrease from 66 hours to 22. This should result in a reduction in the number of files in available from 50 to 7-9 per route. Also, the number of timegraph locations will increase from 55 to 75.
To assist in sorting and filtering images, we will also be adding a new "region" parameter to the available list, e.g.:
The following regions will be available for both routes and locations:
After a short grace period to enable you to change your systems, the routes and locations in the "old" region will be removed. This is planned to be implemented on 1. July, and will affect the following routes and locations:
Total of 16 routes: AAL-ENRT, ENAN-ENAT, ENAT-ENSS, ENBO-ENVR, ENLX-ENBG, ENLX-ENFL, ENLX-ENKH, ENLX-ENRT, ENLX-ENSX, ENLX-ENTS, ENLX-XZFR, ENMS-ENRA, ENRA-ENBO, ENTC-ENMH, ENTS-ENRT, ENZZ-ENKB
Total of 13 locations: ALVDAL, AURLAND, BLAKSTAD, BYKLE, DALSBYGDA, ELVERUM, GULSVIK, NORDREISA, NOTODDEN, SPYDEBERG, TANA, ULLENSVANG, VEGGLI
