Yr

Yr is a weather service run as a collaboration between the Norwegian broadcaster NRK and the Norwegian Meteorological Institute; the copyright line names both for 2007 to 2026. Its home page describes forecasts for more than 10 million locations worldwide, with search, a map, weather warnings, water temperatures and mountain passes.

Linked services include a subjective forecast chart, a text forecast for Norway and satellite images, all from the meteorological institute. Apps exist for iOS and Android. For developers, the footer links the MET Weather API, whose open data is licensed under CC BY 4.0. The API terms state no fee and no service level agreement, set a limit of 20 requests per second per application and describe customised data through the ECOMET catalogue, without a price.

• Forecasts for 10 million places. The home page describes forecasts for more than 10 million locations worldwide. Coverage is broad, though the pages we read do not state how forecast quality differs between Norway and other regions.
• Warnings and practical layers. Weather warnings, water temperatures and mountain passes sit next to the map and search. These suit hikers, boaters and drivers in Norway more than someone looking only for a city forecast.
• Services from the met institute. The subjective forecast chart, the text forecast for Norway and satellite images are linked from Yr and come from the Norwegian Meteorological Institute.
• Mobile apps. Yr offers an iOS app and an Android app under the package no.nrk.yr. The pages we read do not list app features separately from the website.
• MET Weather API. The footer links Yr for developers, which leads to the MET Weather API documentation and terms. Open data is licensed under CC BY 4.0 and must be attributed with a link to the licence and a note of changes.
• Rate and request rules. The API terms set a limit of 20 requests per second per application and require a User-Agent with a company email or website. Coordinates must be truncated to four decimals, or newer products return 403 Forbidden.
• Caching discipline. Clients must not re-request data before the Expires header time and should use If-Modified-Since. Deprecated versions are flagged with status 203 and are usually terminated after about one month.

• A hiker or sailor in Norway. Mountain passes, water temperatures and warnings are combined with a map, so one site covers checks that otherwise need several services.
• A developer building a forecast widget. The MET Weather API has no stated fee and open data under CC BY 4.0. The developer must send an identifying User-Agent, cache properly and stay under 20 requests per second.
• A business needing customised data. The terms point to the ECOMET catalogue on ecomet.eu for customised weather data. They give no price, so the business would have to approach the catalogue directly.

For ordinary use, open the Yr site or install the iOS or Android app and search for a place. For developers, the Yr for developers link in the footer opens the MET Weather API documentation and terms on developer.yr.no. Every request must identify the application with a User-Agent that includes a company email or website, because clients that cannot be contacted risk being blocked without warning.

Coordinates need truncating to four decimals. Cache responses using the Expires header and If-Modified-Since. The pages we read do not describe a sign-up or key process, so read the terms first. Higher traffic than 20 requests per second needs a special agreement.

Yr is a collaboration between NRK and the Norwegian Meteorological Institute, covering more than 10 million locations with warnings, water temperatures and mountain passes.

Developers get the MET Weather API under CC BY 4.0, but the terms promise no service level, cap traffic at 20 requests per second and may block clients without a contactable User-Agent. Customised data runs through ECOMET, which the terms do not price.

In our weather apps ranking Yr stands at #9 of 12: the products next to it are KNMI above and Meteo-France below. Established names take the places after the first three, in ranked order, and we give no numeric score.

Counting headquarters, 5 out of 12 sit in Europe; for Yr that is Norway.

The developer rules are unusually specific.

Coordinates are truncated to four decimals, with five or more returning 403 Forbidden on newer products; clients must wait for the Expires header and use If-Modified-Since; deprecated versions are flagged with status 203 and are usually ended after about one month.

Access logs for api.met.no are kept in the operator's own data centre in Oslo.

Apps exist for iOS and Android.

Pricing as recorded: No fee in the MET Weather API terms; open data under CC BY 4.0; custom data via ECOMET.

The MET Weather API terms state no fee, no price and no service level agreement, and say there are no guarantees of delivery and no option to obtain an SLA. Open data is licensed under CC BY 4.0, so reuse needs a link to the licence and a note of any changes. Customised weather data is offered through the ECOMET catalogue on ecomet.eu, and the API terms give no price for it. The consumer site and apps are not described with a price on the pages we read. The practical cost for a developer is therefore compliance effort: attribution, caching, truncated coordinates and a contactable User-Agent, rather than a licence fee.

Basis: yr.no, read for the Best Weather Apps in 2026 guide (reviewed 13 November 2026).

The API terms state that api.met.no access logs are stored in the operator's own data centre in Oslo, Norway. The copyright line names the Norwegian Meteorological Institute and the Norwegian Broadcasting Corporation, and the country is Norway.

The pages we read do not describe certifications, data retention periods for the apps or the handling of location data in the consumer apps. Developers should note that clients without a contactable User-Agent may be blocked without warning, which is an operational rather than a security measure.
