The climate of Alaska (United
States of America)
The state of Alaska is located in the northwestern part of North
America and is separated from the mainland of the United States of
America by Canada. Because of its geographical location (about one
third of Alaska is situated above the Arctic Circle) Alaska is the
coldest state of the United States of America. Because of the Alaska
Current warm sea water flows along the southern coasts of Alaska.
Because of this temperatures during the winter are higher here than
you may expect from a region located this far north. However, this
does not apply to the northern part of Alaska causing large
differences in temperatures in Alaska. In Anchorage, Juneau and Dutch
Harbor winters are warmer and shorter than in the north. In Dutch
Harbor on Akmaknak Island the coldest month is January. During this
month the average 24 hour temperature is just below freezing point.
During the summer average daytime temperatures are 10-15 degrees
Celsius (50-59 degrees Fahrenheit).
The climate of Alaska can be divided into several
climate zones. The southeastern part of Alaska where the capital
Juneau is situated has a moderate maritime climate (type Cfb)
according to the Köppen Geiger climate classification. This fairly wet
part of Alaska can record up to 1,300 millimeters of annual
precipitation. However, this is also the warmest region. The largest
part of Alaska has a cool land climate (type Dfc). During the summer
temperatures are above 10 degrees Celsius (50 degrees Fahrenheit)
here. The most northern part of Alaska has a tundra climate (type ET).
During the winter it gets extremely cold here, both during day and
night. During the summer temperatures rise just above freezing point
and subzero temperatures during the night are not uncommon.
