We have reached the time of year when the SMOS “thin ice thickness” readings start being affected by surface melt, but let’s take a look anyway:

That area of the Laptev certainly appears to be either thin or melting.

Meanwhile on the Canadian side of the Arctic the fast ice off the Mackenzie Delta is starting to get damp, even though the river itself still looks to be fairly well frozen:

Once July arrives bottom melt should have started in earnest too, but for now let’s stick to the surface. Here’s the Climate Reanalyzer map of Arctic surface air temperatures at 06:00 UTC this morning:
