The climate of Artigas Base
Artigas Base, located in
Antarctica, features a severe weather pattern prevalent on this frozen continent, classified as Ice Cap climate (EF) according to the Köppen climate classification. This implies a permanent layer of ice and snow, with temperatures remaining far below the freezing point throughout the year. With temperatures ranging from a high of -26°C (-14.8°F) in
January to lows touching -64°C (-83.2°F) in
August, the area experiences the harshness of extreme cold.
A notable parameter is daylight, varying significantly across different months. In
December and January, one can expect up to 18.5 hours to 19.6 hours of daylight respectively, while
June and
July dwindle to around 5.2 hours to 6.1 hours. Sunshine hours follow a similar path, offering most sunlight from
November to January with 14 to 20 hours and least from
March to August with nil to minimal hours. Another important parameter is the UV index, remaining at low levels, primarily zero to one across the year.
Various unique weather patterns characterise this region - including months of near-total darkness followed by period of constant day illuminations and months when the sun barely crosses the horizon. This drastic swing in sunlight hours impacts not just the visibility but also the temperature and UV index throughout the year.
