Helsinki activity forecast

Planning notes for Helsinki

Helsinki sits on a granite peninsula with the Baltic on three sides, and its seasons are sharply different. Summer evenings are extremely long; winter afternoons are not.

• Read the daylight factor before the temperature in winter — the outdoor window closes early regardless of how mild the day is.
• In summer the best window often falls late, because the light lasts far beyond a normal evening.
