I had a diver down on my boat yesterday to clean the hull off prior to putting it on a trailer when it's available. He assured me the cold would not be a problem. He said he had dived in Norway in the winter etc. He has over 18 years of experience and is a top dive instructor so knows his stuff.

It turned out the water temp in Burry port was 4C - he had a dry suit and hood etc but after 1hr nearly ended up with hypothermia - said it was much worse than Norway!!!

I was talking to an elderly gent who was down checking on his boat - said he didn't feel the cold - turned out he was on the Atlantic convoys to Russia during the war. He was born in 1913 - 96 years old and down checking on his boat in the freezing cold - awesome old bloke!!!

I didn't realise the sea temp was so cold - so much for the gulf stream. God help you if you fall in - wouldn't last long..............

The dive instructor is a girlie wimp, when I was a lad and started diving many moons ago it was march in mixed freshwater lochs at around 4C using a 5mm wetsuit.
A drysuit was still a luxury item then!

Freshwater at minus 4 C is called "ice"
The sea doesn't get down to that sort of temperature, even Artic water is still around 2C

It must do because the sea at Burry Port froze a few times last week.

the temp when he dived was +4C though.

Baby... Here in the Lakes, it never gets above 4 once you're down 70'. Until about mid-June, it's that temperature from about 20' down!

Years ago, a friend of mine who runs a dive shop in Tobermory used to run a "special" in May... If you booked a spot on one of his boats, you could dive "all you want" for a flat rate. Wetuit divers did one dive. Drysuit guys would do two. Either way, the boats were back in by about 1:00 PM!

That will be freshwater run off or conditions freezing the top layer. A few inches down it won't be below around 4C in the UK and 2C worldwide.
I personally have never seen less than 2C even in deep water Artic waters.

There is no freshwater in that harbour - it is completely tidal.

The diver was a little shocked - he tumbled in to find that he was only up to his chest!!!

There are always freshwater peaks even in tidal harbours due to rain and freshwater outflows.
The chart shows current sea temperatures around the UK, there will be small variations in lochs and inlets with lots of freshwater and shallow areas <1m or so but not that much variation.
