Is the ocean water warm enough to swim in (pleasantly) at English and European beaches in the summertime?

Question

People obviously go to English and Baltic and other European beaches in the summertime, but does the water warm up enough there that people can actually swim in the ocean? Do people swim at Irish or Scottish beaches, or is the water too cold?

Answer 1

People swim in the ocean all over Europe in summer.
Now to the "warm enough to swim pleasantly": I normally see especially the male half of the population signaling the water temperature by showing a small distance between two of their fingers saying "it is that cold" and grinning. So the water is relatively cold but still warm enough to swim in.

Typical water temperatures at the Atlantic coast in Europe are around 18C/65F. The water in the Baltic Sea and in the Mediterranean is warmer.

Answer 2

I am from Denmark and the water is warm enough to swim in from June to September. It warms up rather quickly because of the amazing amount of daylight that we have in the summer months (it is light from 5:00 to 23:00), and very comfortable day temperatures from 20-30 degrees Celsius.

Answer 3

im not sure. maybe the sea but the atlantic ocean (ireland) will probably be a bit to cold to swim in. places around the coast of england should be warm enough as this is only really a sea not an ocean.
