2018 is well (over 3 centuries in either extent or area) below 2013 and 2014. Nearly 3 centuries above 2012 extent. The 2012 source is (UH) SSMIS, AMSR2 data does not start until August, so has some additional uncertainty.
Attached is an animation of the (North) Greenland Sea comparing 2018 with 2013 which has the lowest extent for end of July. Sea Ice looks rapidly melting, and more of the fast ice has become mobile.
