I've waited a few days extra to get all the images in, so now it's time to have a look at what air and sea surface temperatures did in the past month, and compare that to what happened in previous years.
As in the previous blog post on temps in June I have made use of the Daily Mean Composite page, compiled by the Physical Science Division of NOAA's Earth System Research Laboratory. Because of the switch in weather patterns halfway the month, I've decided to retrieve images for the first half and one for the second half of the month (click for a larger version):
Quite the difference, eh? First half of the month blazing hot, almost all over the Arctic. Second half of the month the clouds move in and all of the heat moves to eastern Siberia. The Canadian Archipelago was a couple of degrees warmer than climatology all through the month.
Here's the image for the whole month:
But of course, sea surface temperatures are more important when it comes to melting, so let's have a look at what happened in the Arctic waters.
Sea surface temperatures
These images come from the EORC-JAXA webpage and here's what the SST anomalies looked like in the past month:
Just as in previous comparisons this year resembles 2005 and 2009, but is almost the spitting image of 2007. Lots of warm waters on the Pacific side, and of course very warm in the Kara and Laptev Seas.
If it hadn't been for the switch in weather patterns, I think it's reasonable to say this year would have left 2007 in the dust. Let's see what those warm waters can do this month.
