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!

i think he mean't minus 4%. still crazy though!!!

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!!!

BruceB · 12 January 2009, 23:42

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.

codprawn · 13 January 2009, 01:19

Those are the temps I expect the sea to be. But I can assure you the actual harbour temp was 4C and must have been lower last week as it froze.

prairie tuber · 13 January 2009, 06:32

More of the same here. -34 C right now...

codprawn · 13 January 2009, 13:14

I met 2 people the other day from Canada. They were horrified how cold it was here - even though it was -30 where they were from they reckon if felt colder here - must be the wind and damp that does it!!!

When I used to do my climbing in the Alps it was often -22 and sunny - we would be in normal shirts and some girls were getting a tan!!!

prairie tuber · 13 January 2009, 15:17

I believe that. I've heard people from the prairies here tell me that they had never been so chilled as when visiting Scotland during the winter. That may be in part to the humidity levels there bodies are used to, and perhaps also cold weather clothing that may work well here but not there. Most of my cold weather clothing works best for very cold but relatively low humidity. Really damp conditions will carry that chill right through that clothing.

Cold weather clothing that may work well in one region could be the worst thing in another. This is where getting local wisdom is important. For example when it is about -10 C or colder here a Gore-tex shell is one of the worst materials for an outer shell that you could wear. It does not breathe well enough at all, and you will get soaked from the inside out.

BruceB · 13 January 2009, 16:32

I have lived in both Canada and Scotland and it is the humidity levels of our climate that are the killer.
It is much colder in canada away from the coasts but is very dry

And I am not about to start yet another timewasting argument with Codprawn when he doesn't read the posts properly as he now seems an expert in marine physics (and I spent four years working in this field from the med to the high Artic so what do I know?

)
No matter what he says there will be no more from me on this repeating the same post deiffrent ways, and the diver is still a sissy
