Weather in helsinki
Helsinki has a climate that is transitional between maritime and
continental. Summers are warm and bright, temperatures ranging from
a cool 59Â°F (15Â°C) up to a hot 86Â°F (30Â°C) in the warmest month of
July. Days are long and sunny, with up to 19 hours of daylight.
Towards the end of September temperatures cool down drastically as
days grow shorter, and by November the weather is at freezing point
as the cold, snowy winter sets in. The city is blanketed by snow in

where the sea itself freezes over, and it is never fully daylight.
Spring arrives late, in early April.
