HELSINKI, FINLAND

Hi Everyone. Today's trip is to Helsinki, Finland. It's a new place
for me, I know nothing about it.
Helsinki is the capital and largest city of Finland. It is located in
southern Finland, on the shore of the Gulf of Finland, an arm of the
Baltic Sea. Helsinki has a population of 614,074 as of January 2014.
Helsinki is Finland's major political, educational, financial, cultural
and research center as well as one of northern Europe's major cities.
Approximately 70% of foreign companies operating in Finland have
settled in the Helsinki region.
In 2009, Helsinki was chosen to be the World Design Capital for 2012 by
the International Council of Societies of Industrial Design. In
2011, the Monocle Magazine ranked Helsinki the most livable city in
the world in its Livable Cities Index 2011.
Helsinki is spread across a number of bays and peninsulas and over a
number of islands. The inner city area occupies a southern peninsula.
Much of Helsinki outside the inner city area consists of postwar
suburbs separated from each other by patches of forest. A narrow, 6
mile long Helsinki Central Park that stretches from the inner city to
the northern border of Helsinki is an important recreational area
for residents.
Major islands in Helsinki include Seurasaari, Lauttasaari and Korkeasaari.
Other significant islands are the fortress island of Suomenlinna
(Sveaborg) and the military island of Santahamina. Finland's biggest
zoo is located in Korkeasaari.
February is normally the coldest month with average temperatures between
19 and 29 degrees Fahrenheit. July is normally the warmest month
with average temperatures between 58 and 71 degrees F. August tends
to be the rainiest month with an average of 3.15 inches, and a yearly
average of 25.79 inches of rain. February is normally the snowiest
month with an average of 9.4 inches, and a yearly average of 28.3
inches of snow.
I hope you enjoy this trip to Helsinki, Finland.
