Kulosaari Weather in December
Kulosaari, Helsinki, Finland
About Kulosaari in December
Kulosaari's island position in Vanhankaupunginlahti bay provides water-moderated temperatures and high humidity, with sea fog common in late spring and early summer mornings. The low-density villa housing and abundant mature trees create a park-like cooling effect, keeping summer afternoon temperatures 2–3°C below nearby dense mainland neighborhoods like Sörnäinen.
