Arctic temperatures
Greenland has an arctic climate with average temperatures that do
not exceed 10° C (50° F) in the warmest summer months. In the
southern part of the country and the innermost parts of the long
fjords, the temperature can, however, rise to more than 20° C (68°
F) in June, July or August.
Variable coastal and inland climate
The sea around Greenland affects the climate on land. The
stretches of coastline close to the open sea, in particular, are
cooled by the sea. Therefore during the summer months it is warmest
and driest on land closest to the ice
sheet. In all parts of the country the weather is locally
changeable and can vary from fjord to fjord and from one valley to
the next. You can get the best weather information by enquiring at
local tourist offices or asking local people.
Low humidity
The air is generally very dry in Greenland in relation to many
other countries, and because of this low humidity the low
temperatures do not feel as cold as you might expect. On the other
hand, the dry air means that you must drink more water than normal.
The low humidity also means that you can see further than you are
probably used to. Mountain crests that appear to be close are
usually further away than you think and this should be borne in
mind when planning a hike.
