  ## Climate
  
  Österforse has a borderline continental/subarctic climate that is quite moderate in nature considering its inland position and latitude. Summer days are very warm for North Central Sweden, being heavily affected by its low elevation in comparison to areas further west such as Östersund. Temperatures are heavily dependent on wind direction and the convergences of warm southerly and cold northerly air. As a result, cold snaps can be quite extreme, resulting in an all-time low of −43 °C (−45 °F). The all-time heat record is from July 2, 2015 with 32.8 °C (91.0 °F) in an otherwise chilly summer.
