In early April JAXA Arctic sea ice extent is 3rd lowest for the date, albeit in a “statistical tie” with last year:
The Alfred Wegener Institute’s regional extent graphs reveal an intriguing divergence on the Pacific periphery, where sea ice extent in the Sea of Okhotsk is at an all time low for the date in the AMSR2 record:
On the other hand extent in the Bering Sea is close to an all time high:
On the Atlantic periphery extent is less extreme, although there is currently open water north of Svalbard:

Looking at the third dimension, here is the AWI’s CryoSat-2/Sentinel 3/SMOS Arctic sea ice thickness map at the end of March:
Here too is the associated volume graph:
Note that thickness and hence volume is likely to be biased high on the Atlantic side of the Arctic due to continuous radio frequency interference affecting SMOS data:

Here’s our NSIDC replacement service, summarising atmospheric conditions over the Arctic during March 2026:


The NSIDC monthly average extent graph for March shows 2026 slightly above last year’s record low:

In mid April JAXA extent is second lowest for the date:
After a recent rapid decline Bering Sea extent has stabilised:
On the opposite side of the Arctic, extent in the East Greenland Sea is in a “statistical tie” for lowest for the date:
Here’s the final “near real time” CryoSat-2/Sentinel 3/SMOS Arctic sea ice thickness map for the spring of 2026:
Here too is the associated volume graph:

and the latest SMOS/SMAP “thin ice thickness” map:

Seems like we’re back on track.
