In S. Brittany the sea is 3°- 4°c higher than normal. Who would want to go to the Med when it's like that?

There was no marked heatwave there; only a few days when it was over 30° but most of the time it was in the mid 20's and not a cloud in the sky. Take that with F.3/4 winds and you have the paradise for sailing.

The sea temperature in the Shetland islands is 12°c this summer, which is about 4° below the temperature that starts to make your feet ache the moment you step in. :-)

I remember playing in an early season outdoor league water polo match when the temperature was only 8°c. Some players had to be carried out of the water.

I also had a few swims in the sea in Iceland when I worked there during the student summer holidays. Now that was cold! A swim race was organized across the harbour for fishing men in their full gear including oilies.
 
Having recently arrived in Guernsey I am surprised at how much the sea temperature seems to vary from day to day, that is comparing different days at the same state of tide. Typically it's about 18 degrees at the moment, but it has been higher in recent days.

It can depend on the wind. If it's offshore or from the north (in the northern hemisphere) it can blow the warm upper levels of the water offshore which is then replaced by colder water from deeper down. Called an upwelling event.

Thanks ronsurf, every day is a school day!
 
The sea temperature around the Isle of Man has just about got up to 15^c. When I lived in Sicily the sea temperature when I went snorkelling on New Year’s Day was 16^c :eek:
 
All I know is the barnacles and seaweed are having great time.

Meanwhile NOAA seem to be predicting a weaker than average hurricane season as the Atlantic is unusually cool
 
Strange the variations - Western Channel and Mer d'Iroise (that's the bit which once had a weather forecast area called Ushant) have been around 17 or 18 for past month or so, a little higher south of the Pte du Raz, and where we are currently (Ile d'Yeu) and adjacent sea areas it's around 20. Does seem to change on a day to day basis tho - still wet suit temps for me, although it seems to suit the fish . . . lots of sardine and good sized mackers but haven't hit a bonito yet.
 
Is it the warmth of the sea making the water in Falmouth a strange colour? Algae bloom?

The regular clear/bluish colour is now a very pale/yellowish/bluish tinge and not so clear.

Anchored in 2.6m the other day, on sand, off Maenporth beach, it was hard to see the chain and certainly not the anchor. Very often you can see it all.
 
Unusually warm also in the southern Scandinavian area. Presently sea surface temperature seems to be around 20 degrees in large parts of the Baltic proper, around 19 degrees in Kattegatt/Skagerrak.
