Tallinn, Estonia — Climate
Tallinn Weather
Like the rest of coastal Estonia, Tallinn has a temperate climate, with warm summers and severe winters. Temperatures range from a summer average of 21°C (70°F) to an average in winter of -8°C (18°F). Being on the Baltic Sea the city is subjected to sea breezes and humidity, and its northern latitude means long summer daylight hours (the longest summer day stretches to 19 hours) and dark winters when daylight lasts sometimes only six hours. The cold winter does not necessarily mean constant snow; in fact snowfalls are few and far between. When it falls it stays, however, and there tends to be a layer of snow on the ground constantly between December and March. Summertime brings unexpected rain showers, so an umbrella and light raincoat are recommended.
