Sea temperatures are climbing rapidly this year and I've only been monitoring them over the last few years but they are getting to the point now where they would be at the end of the summer and if the good weather continues it will be very interesting to see how high they can get with possible implications for the winter. I was just on the Channel Coastal Observatory website and surprised that Boscombe is already over 20c although its just dropped back to 19.9c as this is near live monitoring and Westonbay in the Bristol channel is reporting 20.1c which is currently the hotspot for all the stations reporting on the website. 20c+ sea around the UK is very warm and I thought I would mention the website for anyone else that is interested. If you click on the individual stations you can see the historical charts which will depend on when the data bouy was deployed for that location but it will give you an idea of what sea temperatures we've had in recent years.

Keep in mind also that after the mild winter, the start off point was higher than usual.


What the implications are for winter very much depend on the weather between now and November, so much too soon to speculate.

Just over a week ago I noticed the sea temperatures at Solent where 19.8C.

This was on the local surf website, I did assume that this was a local coastal water temperature and not reflective of the open channel.

It's currently 20.4C at 3am in the morning :-)

interesting when I told my hosts in  Naxos greece, that we swim in the sea when its ony 18 or 19 degc, that thought it was highly amusing especially as they consider  it too cold to swim in Greece  until it's  at least 25 or 26 deg c in August http://www.seatemperature.org/europe/greece/

Yes thats correct and I could have been more clear that these temperatures reflect what you will experience if you go to the beach and take a dip rather than the outer channel/Atlantic etc, I think the majority of the data bouys are located within a few miles at the most of land. I did wonder how the Atlantic was doing as I was aware when we were nearing the end of the winter of some people mentioning that the brutal weather in the US was lowering North West Atlantic temps and that this may mean that the summer would be less Atlantic dominated allowing the Azores high and euro highs to develop and ridge in and maybe give us some good weather. But I don't know whats happening there right now and how those temps have been modified since then. If the temperatures keep been pushed up though and that could go on well into September it could be an interesting Autumn if we have warm waters around the UK as they would feed any low heading in our direction. There are of course many things to consider and coastal temps SST's etc are just a few.

This is my favourite SST viewing site.


You can clearly see the large near-shore positive anomalies (3-4*C widely) and how SSTs are a lot closer to the LTA in the middle of the Channel and also the Irish Sea.


There's a notable area of positive anomalies to the SW of the UK though, and the North Sea is impressively far above average overall, which is of great relevance to us with the easterly component to the airflow over the next 4-5 days.


Then there's that remarkable band of positive anomalies extending from just north of Iceland to the North Coast of Norway. I believe the reduction in SST gradient as you head north from the UK may be helping to keep the jet stream relatively weak close to our shores.


King of all the positive anomalies in our part of the hemisphere are those in the Baltic Sea. Scandinavia is having yet another toasty summer!

 SSTs are slightly warmer than usual - already exceeding 18C off parts of SE and SW England, thats 2 degrees above the LTA for mid July and a result as you rightly point out of the warmest year since records began...

Thankyou for the links and info guys, sorry for replying late but I've been away. There is a report on the BBC today about how warm the sea is getting. When I was at beautiful cove in Torquay on monday the sea was very warm it wasn't even slightly chilly!
