After a drop of almost 262 thousand km2 in just three days, it looks highly likely that the maximum for sea ice extent was reached two weeks ago, according to the data provided by JAXA, the Japan Aerospace Exploration Agency (via ADS-NiPR ; it used to be provided by IJIS).
It's a new lowest maximum record, and the third time in a row that extent stayed below the 14 million km2 mark. The previous lowest max on record was reached in 2015 (13.942 million km2), almost beaten last year (13.959 million km2), but this year SIE went lower still and peaked at 13.878 million km2.
This graph by commenter Deeenngee, posted on the Arctic Sea Ice Forum, visualizes maximums from the past and the trajectory to this year's max:
It looks highly likely that the max has been reached for NSIDC daily SIE as well (graph provided by Jim Hunt from the Great White Con blog), a third record low in a row if my eyes don't deceive me:
The drops are mostly driven by sea ice reductions in the Bering and Okhotsk Seas, but will soon be joined by drops on the Atlantic side of the Arctic as well, as the ice is pretty thin there, according to the Uni Bremen SMOS thin sea ice map.
