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 2025 maximum, which occurred on March 22. On this day the extent of the Arctic sea ice cover peaked at 14.33 million square kilometers (5.53 million square miles), making it the lowest yearly maximum extent on record. This year’s maximum is 1.32 million sq km below the 1981-2010 average Arctic maximum of 15.65 million sq km. This continues a downward trend scientists have observed over the last several decades.
