Cold water tolerance

It started today. Walking around in high 40s in only shirt-sleeves. (I mean, yes, I had pants on, too. Don't get me wrong.) Several years ago in prep for my second attempt at a crossing, I would start my cold water tolerance not even in the water, but walking in temperatures that others would consider cold, but without a jacket. See, I had failed my previous attempt (2015) in 55-57F water after 2.5 hours and almost 5k. I didn't want that to happen again. At that time, I had no ready-access to OW to practice in, and pools there (former Soviet Union) were way too hot. So I did a few things. One was being improperly clothed for the temperature and the other was to end every shower with slowly lowering the temp of the water. It apparently worked as I succeeded in my next attempt. The water was a bit warmer (64F) but I never felt cold for the 6+ hours I was horizontal. Now I'm lucky to be near OW. Been traveling lately, but am planning to go to test the water this coming weekend. Coldest I've ever done was last Halloween, 51F, and that was only standing mid-thigh for 10 minutes, then jumping in, stroking maybe 8-10 times, then turning around and walking out. This year I intend on starting early and continuing for as long as I can. What sort of things do you do for cold water tolerance if you a) have no ready-access to OW and b) if you do?

    God gave us here in Boston vicinity 3 days of sun this past weekend, and I swam outside each day. Saturday: 2.35 miles in Walden Pond. So stinking pretty. (My second time as I swam 1.5 miles in it on the 22nd.) Sunday: 0.65 mile in Winthrop in 50-51F water. Horrible. Monday: 1.4 miles in Revere in 54-57F. Wonderful. Working that stupid cold water/salt water tolerance up, slowly but surely. Here's hoping for a few nice sunny days this week. And with that, we've had two days under 65F and cloudy/raining. :doh:

    I lasted 18min in 12C water on Sunday, sans wetsuit. I shivered a lot after I got out, but I was fine after 10min.

    Continued today. Did 15 minutes in 46F. No, not swimming. Simply standing. That's the best I can do so far. I did dunk myself at the very end. But much better than my last time trying this, last Halloween, when I did 10 min standing in 51F, then 5-6 strokes. Getting there, slowly but steadily. IMHO, standing is harder than swimming.
  • IMHO, standing is harder than swimming. Oh dang, I have not kept this up to date. Since the post you quoted, I've done a bunch of other swims at Revere ranging from 54F to 60F. Getting used to it. Check out my Winthrop experience (32 min in 50-51F) vs. what I mentioned about last Halloween (10min standing, 5-6 strokes in 51F). Acclimatization works!
