api.met.no/weatherapi er et grensesnitt mot et utvalg av data fra Meteorologisk institutt. Dataene er fritt tilgjengelige for bruk under disse betingelsene. Se også egne vilkår for bruk av tjenesten.

Alle jevnlige brukere av API anbefales på det sterkeste å abonnere på vår epostliste for API-brukere siden dette er den eneste kanalen vi vil kommunisere planlagte endringer på utenom websidene (se arkivet for tidligere meldinger).

For driftsstatus and vedlikeholdsmeldinger, se status.met.no (vennligst lag bokmerke i tilfelle siten er utilgjengelig).

For informasjon over hvilke data som er tilgjengelig, samt hvordan disse kan brukes, se dokumentasjonen (engelsk tekst).

Data som eies av andre enn Meteorologisk institutt er ikke tilgjengelig for allmenn bruk. Dette står spesifisert i dokumentasjonen for hvert enkelt produkt. Denne problemstillingen gjelder spesielt radarbildet over Norden og satellittbildene. Les dokumentasjonen for hvert enkelt produkt før bruk.

Nyheter

New API products 2019-03-04

We will shortly launching some new products, mainly of interest for Norwegian users. As described earlier, some obsolete products will also be removed.

textforecast 2.0

We have started the process of cleaning up the old text forecasts, with a new XML format (which can be validated), more consistent data structure and clearly defined areas. All of new forecasts share the same format and schema, including:

  • landoverview
  • coast_en, coast_no
  • seabank_en, seabank_no, seabank_wmo
  • seahigh_en, seahigh_no, seahigh_wmo

To aid in transition from textlocation, all areas are now identified with an id, which can be used to look up the corresponding geographical coordinate polygon. These files can be downloaded from the /areas endpoint, but we hope eventually to be able to include them directly in the forecast.

Textforecast 1.6

We have removed the "land" product (use "landoverview in 2.0) as well as "seaoslofjord" (use "coast_no" and "seabank_no" in 2.0).

Airqualityforecast

For some time we have been working on air quality forecasts in cooperation with several other public services. This is expected to go out of beta soon.

Routeforecast 1.0

This is a new image service for aviation, primarily offshore helicopter flights.

Textlocation 1.0

This product will expire March 15th. Please use the "landoverview" product in textforecast along with the area files.

Errornotifications 1.0

This service hasn't delivered any data for months and will expire on March 15th.

ExtremesWWC 1.2

This product will expire on April 1st, when we are turning off the WSklima service. There might be a similar service on frost.met.no in the future.

Discontinuation of text forecasts 2018-12-21

As mentioned earlier we are discontinuing some little used products from api.met.no, here is a complete list:

On February 1st we will remove the following products from the textforecast service:

  • the route_fbno products (these will still be available for professional users via NAIS which everybody seem to use anyway)

  • the landday/long, seabankday1 and metkyst products (which are used to generate more comprehensive forecasts)

  • the iga_fbno43, easter and miskred products (which haven't been produced for years)

We have checked the logs and all of these have little or no traffic, so we don't expect them to be missed. This is the full list of discontinued forecasts:

easter, landday0, landday1, landday2, iga_fbno43, landlong, metkyst0, metkyst1, miskred_north, miskred_south, route_fbno69, route_fbno70, route_fbno72, route_fbno74, route_fbno75, route_fbno76, route_fbno77, route_fbno78, route_fbno79, route_fbno80, seabankday1.

Also, on March 1st the textlocation service will be discontinued. We will also remove the "land" product from the textforecast service. There will be another forecast product to replace those two products, details of which are to follow later.

At the same time, the product "seaoslofjord" containing forecasts for Skagerrak and for the Norwegian coast from the Swedish border to Hordaland will be discontinued. Forecasts for Skagerrak can be found in the "seabank" product, while forecasts for the complete Norwegian coastline can be found in the "coast" product.

We will soon also remove the errornotifications service, which is no longer producing any data. This will be replaced by specific status messages for each product.

Endringslogg

Routeforecast: 1.0 out of beta: 2019-05-14

No further changes planned, product considered stable and can be used in production.

Aviationforecast: aviation text forecasts moved to separate product, 2019-04-24

Since textforecast version 1.6 is deprecated and will be removed soon, we have moved the aerodrome and IGA forecasts to a separate product. This will enable them to keep stable while the other text forecasts are in the process of being updated to 2.0 standard.

Routeforecast: New products, back to beta: 2019-04-04

Type Wave has been replaced with a similar but more precise product helicoptersignificantwaveheight (existing requests will be redirected). In addition two other new products have been added, helicopterlightningobservations and helicoptertriggeredlightningindex.

Due to constantly changing requirements we have added back the beta status for routeforecasts. Further changes may be expected, we do not recommend using this service in production environments unless in cooperation with MET Norway. We suggest subscribing to the Changelog RSS feed to be informed about further developments.

Volcanicashforecast: Version 0.1: 2019-03-27

First prototype

Sunrise: More data for version 2.0: 2019-03-14

moonposition is now repeated for every day in the interval, not just the first day. We have also added a phase attribute to moonposition to show the moon phase for each day, not just the first. Max days is now set to 15.

Since there are only additions to the existing format we assume keeping the existing version is more convenient than bumping so that everyone will have to modify their existing clients.

Upperwindweather: New /status function, 2019-03-11

The new /status endpoint will now list all received files, as well as any errors in transmission.
