How warm does a lake have to be to swim in it?

Answer 1

If the water is below 72 degrees F, you reach a point where warmth is lost faster than can be replaced by physical exertion. Meaning, if you swim 72 long enough, you will develop hypothermia. If you swim higher temps in the lake you can get by as long as you maintain exertion. Don't forget for long swims you need to keep fueling the fire, i.e. eat some carbs or gels. If your body is out of fuel, you won't be able to avoid hypothermia either. Obviously the closer the water is to 72 degrees the more of your maximum effort you need to put out to maintain warmth. Conversely, the warmer it is the easier you can be on yourself. You could always avoid the trouble and swim with a wetsuit hood, hood and top, or full suit, depending on how cold and how long the swim. If you're cutting it close, make sure you have a boat to pick you up in case of trouble, you don't want to burn yourself out and be stuck in open water freezing to death. And always swim with a swim buddy.
