Swedish Meteorological and Hydrological Institute, Swedish administrative authority
The Swedish Meteorological and Hydrological Institute is a government agency based in Norrköping that covers weather, water, and climate forecasting for Sweden. It also carries out research in meteorology, hydrology, oceanography, and climatology, and issues warnings to the public and authorities at all hours.
The institute was founded in 1873 and started issuing weather forecasts in 1880, making it one of the oldest such services in the world. Its main office moved from Stockholm to Norrköping in the early 1970s as the agency expanded its scope to cover hydrology and oceanography.
Many Swedes recognize the institute through its daily radio weather reports, which have been a familiar part of everyday life for generations. The forecasts are widely trusted by both the public and local authorities when planning for rain, snow, or flooding.
The institute is not a public visitor site, so there is no general access to its offices or facilities. Forecasts, warnings, and climate data are freely available on its website and can be consulted at any time by individuals or organizations.
The institute is home to the Rossby Centre, set up in 1997 to model regional and global climate patterns over long time spans. The centre takes its name from Carl-Gustaf Rossby, a Swedish meteorologist who made key contributions to understanding large-scale movements of air in the atmosphere.
