Arctic Sea Ice Maximum 2021

After growing through the fall and winter, sea ice in the Arctic appears to have reached its annual maximum extent. The image above shows the ice extent—defined as the total area in which the ice concentration is at least 15 percent—at its 2021 maximum, which occurred on March 21. On this day the extent of the Arctic sea ice cover peaked at 14.77 million square kilometers (5.70 million square miles), making it the seventh lowest yearly maximum extent on record.
