This page presents Norway's climate context for the current climatology, 1991-2020, derived from observed, historical data. Information should be used to build a strong understanding of current climate conditions in order to appreciate future climate scenarios and projected change. You can visualize data for the current climatology through spatial variation, the seasonal cycle, or as a time series. Analysis is available for both annual and seasonal data. Data presentation defaults to national-scale aggregation, however sub-national data aggregations can be accessed by clicking within a country, on a sub-national unit. Other historical climatologies can be selected from the Time Period dropdown list. Data for specific coordinates can be downloaded for in the Data Download page.
Most of Norway has a maritime climate with mild winters and cool summers. Because of the influence of the North Atlantic Ocean, Norway has a much warmer climate than its latitudinal position would indicate. On an annual basis, the highest normal (1961 – 1990) annual air temperatures (up to 7.7°C) are found along the south-western coast. Outside the mountain regions, the lowest annual mean temperatures (down to -3.1°C) are found on the Finnmark Plateau. The absolute lowest and highest temperatures measured at official weather stations on the mainland are -51.4°C and +35.6°C, respectively. Because of the prevailing westerly winds, moist air masses flow regularly in from the ocean giving abundant precipitation over most of Norway. Areas just inland from the coast of western Norway experience the most precipitation. This zone of maximum precipitation is one of the wettest in Europe, and several sites in this region have normal annual precipitation of more than 3,500 mm.
- During the period 1900 – 2016, the annual mean temperature in Norway has increased by about 1.1°C.
- The temperature increase has been largest in spring in the northern parts of Norway.
- The annual precipitation increased by about 18% during 1900 – 2014.
- The largest increase in observed during spring and the smallest during summer.
