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

Radarlightning: 2019-07-12: Radar animations discontinued, product deprecated

As we have stopped production of most GIF animations, all requests for content=animation will now get the "norway" image instead.

Also, since the content delivered by radarlightning now is a subset of radar/1.5, we have decided to deprecate this product on Dec 1st, 2019. Please update your links to use radar/1.5 instead.

Radar: 2019-07-01: New radar Hafjell, hack for missing animations

Hafjell has been added for types lightning, reflectivity_hires and rainrate_with_phase.

Unfortunately, due to increased server load and shorter production cycles we have not been able to re-enable production of the animations for reflectivity_hires, rainrate_with_phase and most lightning radars. As a workaround, we will be substituting reflectivity_hires and rainrate_with_phase animations with the closest matching reflectivity animation. Similarly, all lightning radarsites will now return the "norway" animation. None of these will appear in the available lists, and are used solely to avoid breaking existing code.

Static images will be delivered as normal, which will not match the animation in content and dimensions. This means you should not use the "small" images as thumbnails for the animations until further notice.

We are working on replacements for the missing lightning animations, as well as a new, improved Radar product version which should be more user-friendly.

Routeforecast: New vcross route: 2019-06-28

ENJS-ENZV has been added

Radar: 2019-06-19: update of v1.5

Radars now produce images every 5 minutes (instead of every 7.5).

Animations are currently only available for reflectivity, xband and lightning (as per the documentation). The undocumented reflectivity_hires animation is now discontinued.

The little-used sizes "large" and "medium" have been discontinued, any requests for these will return "normal" instead. Also, animations are now only available in "normal", use a static image for thumbnails instead of "small".

For a list of allowed options, see /radaroptions (experimental).

Routeforecast: New vcross route: 2019-05-14

The route Korpfjell-ENKR has been added to the vertical cross section products. (No ICAO code has yet to be assignated to Korpfjell, hence the non-standard route name).

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

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