Arctic Temperatures in February: Extreme Cold at the Pole

February is among the coldest months in the Arctic, with temperatures reflecting the depth of polar winter. Based on long-term climatological averages:

Regional Variations

• Central Arctic Basin (sea ice): Most stable extreme cold; minima can reach -50°C (-58°F).
• Coastal areas (e.g., Barrow/Utqiaġvik, Alert, Svalbard): Slightly moderated by ocean heat flux; averages -30°C to -35°C.
• Atlantic sector (Greenland Sea, Barents Sea): Warmer due to Gulf Stream influence; averages -20°C to -25°C.

Drivers of February Cold

• Polar night (no solar radiation since October/November)
• Strong surface-based temperature inversions
• Radiative cooling over snow/ice with high albedo
• Minimal cloud cover in high Arctic (clear skies enhance longwave loss)

Climate Change Context

Arctic amplification has raised winter temperatures ~2–3°C above mid-20th century averages. February 2018 saw unprecedented warmth: temperatures at the North Pole briefly rose above freezing (-1.7°C to +1.2°C), driven by moist intrusions from the Atlantic. Such events are increasing in frequency.
