The annual extent maxima moved to later times and lower values in the last 30 years:
JAXA Charctic
1980s Feb 27, 15.60 M km² | Feb 27, 16.00 M km²
1990s Feb 23, 15.07 M km² | Feb 24, 15.54 M km²
2000s Mar 08, 14.67 M km² | Mar 10, 15.14 M km²
2010s Mar 15, 14.16 M km² | Mar 16, 14.69 M km²
(please note that the covered years are not exactly the same)
A larger extent in the 80s and 90s must have been further south in the so called peripheral seas as the central basin is almost full of ice by this time of the year. These more southern ice floes are more susceptible to earlier melting or to destructive wave actions in only partly ice-covered seas. Therefore the later maximum in the latest decade seems to be logical as it usually is much too cold for melting events in the inner Arctic basin.
An annual maximum in mid February 2021 would be exceptional, but not impossible.
