Malmi Weather in December
Malmi, Helsinki, Finland
About Malmi in December
Malmi's inland position, 10 km from the open sea, gives it Helsinki's most continental-like microclimate, with greater temperature extremes — colder winter lows and warmer summer highs — than coastal districts. The flat terrain of the former Malmi airfield creates an open exposure where cold air pools and radiative frost forms earlier in autumn than in the surrounding built-up areas.
