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!
