Climate, Weather and Forecasts

The climate of the Arctic is characterized by long, cold winters and short, cool summers. There is a large amount of variability in climate across the Arctic, but all regions experience extremes of solar radiation in both summer and winter.

Average January temperatures range from about −40 to 0 °C (−40 to +32 °F), and winter temperatures can drop below −50 °C (−58 °F) over large parts of the Arctic. Average July temperatures range from about −10 to +10 °C (25 to 50 °F), with some land areas occasionally exceeding 30 °C (86 °F) in summer.

It is estimated that temperatures rise faster in the Artic than in other regions of the planet. This polar amplification is driven by stronger feedback effects.

The Arctic consists of ocean that is largely surrounded by land. As such, the climate of much of the Arctic is moderated by the ocean water, which can never have a surface temperature below −2 °C.
