It was the day before thanksgiving and the lakes were still open…
I did a solo scuba dive in Lake Calhoun in Minneapolis this morning.
The water temp at 40 feet was 40 degrees. The temp at the surface was 43 degrees.
The two piece 5mm wet suit, hood and gloves kept me warm until I had to do the 2 minute safety stop at 15 feet and could feel the start of hypothermia.
Oh yeah, what does 40 degree water feel like at 40 feet on bare skin? It feels like the parts of your face that are exposed are burning off with a blow torch. Otherwise the space suit kept me warm as long as I kept moving around.
Next time I’m going to have to find a buddy to go diving with because this shit is getting dangerous at those temps. I might do the Crosby Mine pits this weekend and go down to over 80 feet down but first I’m going to need a warmer hood!!!
