DMI north of 80N temperature is still above zero. Aftermath of insane July? With these persistent southerlies, I wonder if at some point most of ice extent/area will remain in the Beaufort and CAA.

Yesterday the Sun was two times closer to the celestial equator compared to solstice. Normal temperature is falling after it. However, given the forecast, this year is going to delay. Winds north of the Laptev Sea will try to do some damage in the CAB.

The map also shows an arrow indicating a WSW-ward drift of 2nm/day
After this melting season we will certainly measure the ice in nanometres (nm). I can assume that you meant nautical miles but this was confusing for me.

Aggressive WAAs in May/June to reduce albedo, persistent anticyclones in July to input energy, powerful cyclones in August to melt remnants. Is it a perfect melting season? In any case, this year successfully completed 2/3 and the ice looks exhausted.

This is ten days out, and thus completely unreliable, but holy guacamole if it does happen. A big storm like this has been in the long term forecast for a while now, so I don't think it can be ruled out completely. Something to keep an eye on for sure!
We already had one miniGAC and it was a disaster on the Pacific side. Another one or even stronger seems likely.

Image attached for comparison.  It certainly looks to me like it's the highest it's been, but there are similar excursions above the mean at this time of year in 2016 and 2008, as I think others have mentioned upthread.

Edit: replaced image with version with arrows indicating other excursions

Nice comparison. 2008 and 2016 had above average extent losses for the rest of season. Coincidence?

I think it's a bit of a stretch to call DMI 80N all that unusual.  If it keeps rising, maybe.
In 2007-2018 the highest value after July 20 was +1.4°С. The last value is +1.7°С.

DMI north of 80N temperature and GFS 3-day average wind. Both look unusual.

    It would be interesting if an ASIF consenus for <3.5M km2 (with not a small chance of <3) (if there is any such consenus) is more accurate than almost all these offical expert estimates which cluster near or above 4M km2.  At this point I'd put my money on ASIF.
There are different metrics. September mean extent above 4M is quite possible. At least more likely than below 3M. This year has great potential to surprise but also some obstacles.

Forecasted 5 days minimum is well above zero on the Atlantic side. Anticyclone in the Kara will persistently consume this side of the CAB and may lead to more energy stored in the Barents and Kara. Regardless of outcome, freezing season will be interesting.

10-12 knots will push the ice into the Laptev Sea next days. Thin ice is nothing against overheated water.
