Velkommen til api.met.no

English version.

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.

Planned maintainance and discontinuation of old domains 2018-05-09

On Monday May 14th, 2018 from 07:00 to 13:00 UTC we will be running at 50% capacity due to replacement of the cooling system in one of our data centers. All services are expected to continue running, but latency times and timeout errors may increase due to reduced capacity.

Also, as has been noted earlier, the domains api.yr.no and beta.api.met.no will be turned off on June 11th, 2018. Please switch your systems to use api.met.no instead.

Migration completed 2018-02-26

As most of you probably have noticed, we upgraded api.met.no about A week ago to the new version. After some initial performance problems we managed to tune the caches so it is now handling traffic well.

Some users have reported problems accessing the API, mostly related to not handling HTTPS and/or redirects. If you are getting "Failed to get data from weather api. Reason: end tag name </body> must match start tag name <hr> from line 5" this means you are trying to parse the HTML message as XML instead of following the 301 redirect. We are also working on recommendations for users using HTTPS via local proxies.

In order to ensure stability of our own services, we have also introduced traffic rate limiting (and in some extreme cases, blocking) for some users not abiding by our terms of use. If you are receiving 429 status codes it means you are being throttled, either due to a missing/generic User-Agent header and/or excessive traffic (>20r/s).

Finally, we have noticed there is a lot of production traffic against beta.api.met.no (which was only to be used for testing) as well as api.yr.no (which has been deprecated for years). We would like to inform you that these hostnames will be removed within a few months, so please update your applications accordingly.

Endringslogg

Extremeforecast: End of life, 2018-05-01

Discontinuation of extremeforecast has been postponed until June 1st, 2018.

Sunrise: version 2.0 beta: 2018-04-25

XML format trimmed, toned and beefed up, date and offset params are now mandatory. Expected to go into production in beginning of May.

Textlocation: discontinuation of flood warnings, 2018-04-05

Since NVE now offers flood warnings in standard CAP format via their API, there is no longer any requirement for the MET API to offer these in our proprietary format. As such they will no longer be issued, and the type parameter will be removed in a later update.

To download flood warnings in CAP format, please visit the NVE API at .

Mountaineasterobservations: version 1.0 : 2018-03-26

As of 2018 this product is no longer being produced. The service will be removed from the API on June 1st.

Extremeforecast: End of life, 2018-03-15

The extreme warnings have now been superceded by the metalerts product. The extremeforecast service will be discontinued on May 1st, 2018.

Textlocation: removal of extreme, 2018-03-15

From May 2018 all "extreme" forecasts will only be delivered via metalerts. This means those elements will no longer be present in the textlocation XML, instead they must be fetched as CAP from the metalerts product on the API.
