On average 50.4% of sea ice gain from minimum to maximum done, and 185.4 days to maximum

Projections of the Unknown Quantity. (Table JAXA-AA1)

Average remaining sea ice gain (of the last 10 years) would produce a maximum in November 2024 of 24.95 million km2, 1.18 million km2 above the record low of 23.76 million KM2 in 2016, and 5th lowest in the 46 year satellite record
___________________________________________________
In an average year sea ice reaches the false maximum in late June/ early July and the false minimum in early September, and then sea ice extent makes the final run to the maximum in late October /early November

NSIDC 5 Day trailing Average -  GLOBAL SEA ICE AREA:  17,724,210 KM2 as at 01-May-2024

- Area loss on this day 9k, which is 49 k less than the average gain on this day (of the last 10 years) of 40k,
- Area gain from minimum on this date is 3.79 million km2, 0.17 million km2, 4.6% more than the 10 year average gain of 3.62 million km2.

- AREA is 10th lowest in the 45 year satellite record

- Area is  0.92 million km2 LESS than 1980's Average
- Area is  0.47 million km2 LESS than 2010's Average
- Area is  0.06 million km2 LESS than 2016
- Area is  0.64 million km2 MORE than 2018
- Area is  1.06 million km2 MORE than 2019
- Area is  0.04 million km2 MORE than 2022
- Area is  0.78 million km2 MORE than 2023

On average 64% of sea ice gain from minimum to maximum done, and 189 days to maximum

Projections of the Unknown Quantity.
_____________________________________________
The false maximum passes sometime between late May and late June. 
From then average daily losses continue until the false minimum in early/mid September.
Sea ice Area then normally makes the final run to the maximum in late October /early November.

The projected 2024 maximum is 19.75 million km2, 2.14 more than the November 2016 record low maximum of 17.61 million km2, which would be 5th lowest in the 46 year satellite record
