We will shortly launching some new products, mainly of interest for
Norwegian users. As described earlier, some obsolete products will also be
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
- 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.
We have removed the "land" product (use "landoverview in 2.0) as well as
"seaoslofjord" (use "coast_no" and "seabank_no" in 2.0).
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.
This is a new image service for aviation, primarily offshore helicopter flights.
This product will expire March 15th. Please use the "landoverview" product
in textforecast along with the area files.
This service hasn't delivered any data for months and will expire on March 15th.
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.
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
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
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
- Radar: 2019-06-19: update of v1.5
Radars now produce images every 5 minutes (instead of every 7.5).
The little-used sizes "large" and "medium" have been discontinued,
any requests for these will return "normal" instead.
For a list of allowed options, see /radaroptions (experimental).
- 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
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
- Volcanicashforecast: Version 0.1: 2019-03-27
- 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
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.
