If anything in the last month the negative anomalies in the North Atlantic (40-60N and 10-40W) have lowered a little more when compared with last month's values using this NCOF data that I have pieced together. There are pockets of -3°C anomalies rather than the -2°C of last month. The Davis Strait has also cooled with respect to last month too, but there are still some high SST anomalies across the Grand Banks of Newfoundland. The Norwegian sea has positive anomalies, but not quite as warm as August. I don't what could be causing the isolated but intense cold anomaly of Brittany but it's warmed out a little since last month.

I prefer this site, http://www1.ncdc.noaa.gov/pub/data/o...y-anom-bb..gif , which if anything shows a smaller 'cool' area than of late. I think the overwhelming impressions is just how much of the northern Oceans have SSTs above normal.

Your site seems to exagerate the cool pool off Brittany. Looking at actual SSTs there's nothing that looks particularly abnormal. http://www.wetterzentrale.de/pics/Reursst.gif

The cool pool off Britany ist formed during the offshore spell, 6th-11th Sept. During a NW you get a cool pool form off S-SE Ireland, and easterly cool pool off Land's End, all for the obvious reason. Anyone that regularly goes into the sea knows how cold it can get just after 2 or 3 days of offshore winds, it can then take a while to recover.

The south coast is generally 16-17C currently http://www.channelcoast.org/data_man...e_data/charts/ , normal for late September, after quite a period of sub normal temperatures. Felt very pleasant at Sennen recently.

Oh, whilst on the subject of south Channel Coastal Buoys (which I am now, if not before), there is a lot of data available. E.g this should take you to the Porthleven overview http://www.channelcoast.org/data_man...rts/?chart=107
Now try clicking wave spectra. (Well I find it interesting!)

Clean long period wave yesterday (lower pic) not the choppy conditions predicted on the local BBC forecast.
