After early showers, sunny spells this afternoon.
Although temperatures a bit down on yesterday (widely 20-21C) the fresh feel has already gone, so it felt rather warmer than the figures suggest.
The humid conditions made it pleasant to be on the beach http://www.sennen-cove.com/index.htm
2.4mm of rain today (so far), the 1st rain since 1.5mm on 12th.
A large area of above normal SST to the SW now http://polar.ncep.noaa.gov/sst/rtg_l...maly_oper0.png

I was wondering whether these SST anomalies are telling us anything?

Well, wrong Graham replying, but I think, certainly as far as the N Atlantic is concerned, the anamalies owe more to recent weather patterns than vica versa. However, it's not all one way, patterns can be self perpetuatiing.
The SST to the SW the UK has been above normal virtually the whole time since the very mild weather Oct-Dec. Even the 'cool pool' can be traced back to the unusual circulation 18 months or so ago, though it's farless intense at late and wobbles around a lot.
What it does mean is the the sea off the Cornish beaches is 2-3C warmer than last year. Apart from the pleasure that gives us who waste a good deal of time in it.
It also means that here on the Atlantic fringe, SW winds are particularly warm compared with the average. We have also had little sea fog, despite the humid conditions.
Yesterday, Scilly where it was fairly cloudy & breezy, saw a max 21C, typical of mainland SW England, and warmer than many inland spots (Cardinham 18C). Something not reflected in recent maximum temperature forecasts - which continue to largely ignore the effect of the high SST). Maximum temperatures in the coastal far west would normally be lower the areas inland & further east, at this time of year in these conditions.
Certainly the sea off off Cornish beaches is warmer than off much of Atlantic Portugal at the moment, which is actually not that unusual in mid summer..
