I guess so. I'm not sure it curls around the English Channel to that far side of the island. I heard that if one of our pilots had to eject into the North Sea, he had to be rescued within about 1/2 hour before freezing to death.
Typing that got me curious and I found this in Wikipedia.
Despite their northern location, the Nordic countries generally have a mild climate compared with other countries that share globally the same latitudes. The climate in the Nordic countries is mainly influenced by their northern location, but remedied by the vicinity to the ocean and the Gulf Stream which brings warm ocean currents from the tip of Florida.I suspect all things are relative. I sounds reasonable that the Gulf Stream wraps around the north of the British Isles and pushes colder water down from the Nordic Countries to the east coast at Great Yarmouth, maybe?
