This NASA blue marble image shows Arctic sea ice extent on March 14, 2024, when sea ice reached its maximum extent for the year. Sea ice extent for March 14 averaged 15.01 million square kilometers (5.80 million square miles), the fourteenth lowest in the satellite record.

Arctic sea ice reaches maximum extent for 2024

News Release

Arctic sea ice has likely reached its maximum extent for the year, at 15.01 million square kilometers (5.80 million square miles) on March 14, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder.

This plot shows the departure from average air temperature in the Antarctic at the 925 hPa level, in degrees Celsius, for December 2023 through February 2024. Yellows and reds indicate above average temperatures; blues and purples indicate below average temperatures.

Feature Story

The Arctic Rain on Snow Study (AROSS) project, led by the National Snow and Ice Data Center (NSIDC), funded an award-winning StoryMap called "When Rains Fell in Winter," which tells the story of a Nenets reindeer herder named Tokcha Khudi and how a catastrophic rain-on-snow event impacted his annual migration on the Yamal Peninsula in 2013.

This graph shows Antarctic annual sea ice minimum extent, depicted as black diamonds, from 1979 to 2024, based on a 5-day running average of daily extent. The linear trend line is in blue with a 1.7 percent per decade downward trend, which is not statistically significant. A five-year running average is shown in red.
