You must live in the Tropics or something, try jumping into a high mountain lake in the middle of August and you'll scream when you discover how cold the water is.
Lake Superior in August is where you go to have you sperm frozen.
Anything below 78* is cold
Having done so I state that one won’t be able to scream. There would be no air in your lungs from the shock. Don’t forget the North Pacific Current flows along the west coast keeping the water cooler than it would be otherwise.
I made the mistake once of going on a “beach” vacation up in Maine. Not only was there more rocks than sand but that ocean water practically gave me frostbite. In July!
It seems that some are not so familiar with the definition of the word “icy”.... My point was that there was certainly no ice. Columbia River waters in August tend to have temps in the 60s to lower 70s. A bit chilly, perhaps, but certainly not “icy”....
Yes, I have experienced summer swimming in a great variety of northern waters over decades, so I am quite familiar with the bracing feeling of “wow, this feels COLD”... I simply would not have used the word “icy” but I guess I’m too literal-minded.
When I was 13, my parents took us on a two week camping trip through Europe when he got orders back to the states.
We ended up at a campground on some lake in Switzerland on the Fourth of July...all of us kids wanted to go swimming, so we put on our swimsuits and ran to the end of the dock and all six of us jumped off en masse...
I remember vividly the shock of hitting the water, and all of us, underwater, frozen, looking at each other through that weird blue-green colored water with little foam bubbles of air all around all of us...our skin looking pasty white, just...frozen. LOL, that lake was probably fed by a glacier!
The only time as cold or colder than that was when I went to a beach in Gloucester, MA about two years later with a new friend, it was early in June and I dove off some rocks into the water. I had lived in the Philippines for a few years and was used to seawater that was nice all year round.
This was a real shock to me, I nearly bounced off the water, I scurried out so fast. The kid who I went there with was staring at me saying “What did you do that for? I thought you were crazy!”
My first clues should have been: ALL the people STANDING on the rocks looking at the water, and NOBODY in the water swimming! There was surely shrinkage...to use the old crude phrase I remember from the USN: “I was so cold I had to stick my finger up my a** to take a piss!”
