Poor Old Weybourne & SST anomalies

I notice that Weybourne was 4C around noon, so I checked the SST, and it's about 5C off the coast of East Anglia,  https://www.channelcoast.org/realtimedata/ despite the recent warmer weather & sunshine. In fact much of the North Sea is a fair bit colder than normal.

This contrasts with much of the near Atlantic.

The SST is currently >10C at Sevenstones and around Scilly, and >9C around Cornwall & south Devon, around 1C above normal for the end of February.

Interesting because Julian, in another thread (on USW I think) commented on the warmth over recent years being concentrated in the SE.  His possible explanation being an upper trough over the Atlantic & a dominant SW airstream. I wonder if this was linked to the North Atlantic 'cool pool' which has been such a feature for a long time?

Anyway, that 'cool pool' is less evident now, and combined with a cold North Sea will things change. Whatever happens, North Sea coast residents will be wishing for a lack of easterlies in Spring!

Having a breeze off the sea with an SST of 10C, is very different if the SSTs 5C!

Another beautiful day today, and the sand's coming back - at last.

Hi Graham,   yes, the anomalous SW flow I mentioned should correspond (in time) with the Atlantic cold pool, i.e. it is thermally influenced, at least to some extent.  It all got going in the 1980s, though at that time it was linked to Greenland and Iceland beign cold, i.e. being slow to warm up; now they have, of course but maybe meltwater is playing a part in SSTs. 

Apart from Weybourne, Cromer has certainly featured at the low end of Colin's lists for the last two days. (Cromer  - Norfolk's answer to Bude?)  

And today's weather, at least,. did help to erode the SE bias of recent years - or dare I say decades.  There was quite a chill to the air around London - even Heathrow was not that far off the lowest 10 for day max temp.  An 'easterly' spring would make a change.
