If you look at the years 2016-2018 all three of them had some kind of delay in re-freezing.
2016 had an early minimum, but after a quick and short increase ice extent was way below average from end of October on. 2017 rose more steadily than 2016, but fell below the 2010s average end of October. And 2018, many of you will remember, had a late and long minimum and almost record low October values until a longer and stronger increase started end Oct/through November.
For 2019 - starting with a 2nd and maybe late minimum, surrounded by warmer than average seas - I think a delay in re-freezing is likely. IMO at least the much warmer than average peripheral seas (Laptev, Chukchi, Kara, ..., maybe ESS) will freeze later than usual.
