the API itself (see the archives
for past notifications).

Data owned by other institutions than MET Norway
is not available for unrestricted public use. This is

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.
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
<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)
receiving 429 status codes it means you are being throttled, either due
to a missing/generic User-Agent header and/or excessive traffic
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.
- 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
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.
