yr.no is a Norwegian website for weather forecasting and other meteorological information (also in English). The site is a joint responsibility of the Norwegian Broadcasting Corporation and the Norwegian Meteorological Institute.
The website offers forecasts (as graphs, symbols and maps) for more than 9 million places in the world. The Norwegian forecasts are supplemented with textual forecasts, weather radars, satellite images and a wide range of more specialised forecasts. The forecasts are based on data from the Norwegian Meteorological Institute and several international meteorological organisations (ECMWF, EUMETSAT etc.).
The meteorological data on yr.no is available as web services, enabling users free access to high-quality weather data for use with applications, services or research. The free weather data service is very popular, with around 30 million downloads a day. Some mobile phones, like the Vibo T588, use yr.no for their weather service. The online weather service is the 5th most visited weather service on the internet. 
yr.no was launched as a beta version on May 29, 2007, and officially launched four months later on September 19, 2007. It quickly drew a large audience: 87% of the Norwegian population says they know yr.no and 28% uses it daily.
