Just come back from a very pleasant walk along my local beach (near
Margate, Kent). We've hardly risen above zero all day and this morning
I noticed the frost was in patches on the sand. It's windless and flat
low water now and the temperature in my garden is ms02. There is
probably around a quarter of a mile of exposed beach which can't be
too far off zero and I'm wondering if some of the rock pools may
freeze before the tide comes in later tonight. So, as the tide comes
across the cold beach there must be some cooling effect on the sea. I
just wonder how significant it is? I know coastal waters are cooler
than the open sea but I thought that was just due to being shallower
and closer to a feed of colder air off the land. Anybody any thoughts?

Yes, I noticed the SST's in the near North Sea are around 6-7C which I think
is lower than it has been at this time of year for some while.

I quite like this French sea temp chart http://www.meteociel.fr/accueil/sst.php

Seems to be a patch of 'warm' water in the Southern North Sea which is
being cut off by the Dover Strait and the Norfolk Holland part to the
North.

.... here's another one which I use quite a lot - but it is sometimes a
few days behind-time.

.... using the archive he-

http://www.bsh.de/en/Marine_data/Obs...anom.jsp#AnomJ

it looks as if you go back to January 1997 for significantly colder
water temperatures than currently reported; 3 to 5°C generally across
sea-areas Thames, Humber & S. German Bight [averaged through the
month], with tongue of zero to +2°C close to the coastlines of Germany
and Denmark. So 12 years: a notably cold January in 1997, though not
'extreme' by any means.
