Besides information bulletins, the Finnish Meteorological Institute maintains a UVI service that gives advice on when and where people should protect themselves against the sun. UV index values vary in Finland over a wide range, depending on the season.

In addition, Finnish UVI observations are available from the Institute's measurement stations in Utö, Helsinki, Jokioinen, Jyväskylä, Sotkamo and Sodankylä.
