Finland has a severe winter climate similar to that of Alaska
or the Yukon. By contrast the summers can be surprisingly
warm, particularly in the south. At Helsinki, for example,
the average July maximum temperature is 22 °C.
In the north, beyond the Arctic Circle, the long duration
of sunshine compensates to a degree for the northerly latitude.
The south and centre of the country is a low-lying land of
pine forests and innumerable lakes. The north, or Finnish
Lapland, is higher, but only along the north-western border
with Norway do the hills rise above 3000 feet. Off the
south-west coast are hundreds of tiny islands and this is
the mildest part of the country in winter, for the more open
waters of the Baltic do not freeze as often as the Gulfs of
Finland and Bothnia.
In the south and centre of the country the summers are as
warm as those of Denmark and south Sweden. The winters are
long and cold with snow lying for an average of between 90
and 120 days.
In the north of the country the snow cover lasts from mid-October
until late April or mid-May. Here, in the brief Arctic summer,
daytime temperatures may rise almost as high as in the south
and sunshine may average as much as 9 - 10 hours per day.
The weather is changeable from day to day in all seasons however,
for Finland is influenced to some extent by Atlantic weather
disturbances.
Warm clothing is essential in the winter months and in severe
weather there is a danger of frostbite, particularly in Arctic
Finland, if suitable clothing is not worn. One indirect result
of the summer climate is the swarms of gnats and mosquitoes
which appear in the warm weather, particularly in the north.
