The OWC Winter Swimming Guide: (Almost) Everything You Need to Know About Year Round Swimming



NOTE: This was originally published in November 2015. I am reposting it and will likely keep it at the top of the blog page for the remainder of the winter season.

______________________________________________________________

Introduction (Please Read this First!)

Here at OWC, a small group of us will continue to swim during the months of November through March – often in extreme air, water, and weather conditions. It is a very intense challenge that requires a completely different mindset as well as meticulous planning and preparation.

With this in mind, I’d like to take this opportunity to provide you all with more details on exactly how we engage in this type of activity. But before I dive this topic, I need to emphasize three things:

1) OWC winter meetups are NOT “polar bear” swim events.

This is not a “get in, get out” photo op moment that you do on a dare and follow up with hot cocoa in a warming tent. We are serious year-round swimmers, and you will find no support tents, lockers, changing rooms, hot showers, or equipment/gear rental services whenever you come out to any of our meetups.

So do NOT come out to any of our meetups if this is your expectation. At the very least you will embarrass yourself and be asked to leave. At the very worst, you will jeopardize your physical health and safety and potentially eliminate the OWC winter swimming opportunity for all others. Which leads me to my next point…

2) If you are unprepared for this experience, you can easily succumb to very negative consequences such as shock, frostbite, hypothermia, and untimely expiration.

During the warmer months, the key swimming hazards are infrequent and are usually limited to large waves or heavy chops. But the calculus is completely different once the air and water temperatures fall below the 50F (10C) demarcation point.

Under these temperature extremes, “system shock” due to rapid heat loss and cold temperature exposure is almost assured unless you have deliberately taken measures to prevent it. Which is a perfect segue to my final point…

3) As a responsible adult, you need to arrive at each meetup fully prepared to swim in whatever conditions present themselves while out at the lake – and to take full responsibility for your own personal safety at all times.

Bottom line – if you have any difficulties understanding and accepting the aforementioned items, then you candidly have no business engaging in this type of activity. For your sake and for the sake of others, please stay out of the lake this time of year!

Now that I’ve totally rained (snowed?) on everyone’s parade, let’s dispense with the gravitas and delve into the actual specifics of successful cold water swimming…

The OWC Winter Swimming Guide: (Almost) Everything You Need to Know About Year Round Swimming

Based upon my experiences with year-round swimming over the past several years, I believe there are five key areas that you need to focus on in order to maximize your chances for a successful winter swimming outcome.

I’ve organized this information into chapters below – just click on the links for the details:

Chapter 1: The Inner Game – How Your Brain Works in the Open Water (and elsewhere)

Chapter 2: Pre-Swim Preparation – The Real Key to Mastering Cold Water Settings

Chapter 3: Gear Selection – What to Wear During Winter Swim Conditions

Chapter 4: Taking the Plunge – How to Effectively Manage the Swim Start

Chapter 5: The Afterdrop – What it is and How to Manage it 

As with all of my instruction and advice, this is a continual work in progress.  So whenever I discover new information or experience something that adds to or alters this knowledge base, I will be sure to keep you all updated.

See you out at the lake!

Swim Report – February 4, 2018 – Super Bowl Sunday!

The forecast called for up to five inches of snow overnight, so I was expecting the lakefront to be an ungovernable mess. And while I managed to find a close parking spot on Astor Street, I wasn’t encouraged by the blasting winds that ripped the door out of my hand as I opened it to get my stuff.

Fortunately, though, L1 turned out to be much more manageable than any of us were expecting!

The steady winds from the northeast had created a visible current in our swim area, but there were no high volume swells this time. And while the ladder had iced up a bit, it was pretty easy work to clear it with the pick ax and get access to the lake.

We didn’t really get much of a sunrise or sunshine as the weather conditions were overcast, blustery, and rather brisk with a 33F (and dropping) air temperature. So we suited up as soon as possible and got into the 32.5F lake before Ma Nature decided to change her mind – which didn’t take long.

I was planning on getting to the 1/8 mile mark and turning back, but I stopped a bit short of that as some swells had started to appear during the brief time we were in the water. That, coupled with a rather vigorous southbound current, made the return trip a bit more of a challenge than I was expecting. But while it was a shorter swim than usual, it was certainly more of a workout than the last few ones!

The post-swim experience was rather brutal as the wind had picked up and was continually assaulting us as we hastily tried to change out of our wet gear. So I decided to just remove my hood and gloves, throw on my swim robe and winter coat, and high tail it to my car to finish changing in there!

This turned out to be a wise move as I had only been out of the water for about 10 minutes total, and I was now safely ensconced in a heated car. So my afterdrop, while still present, was much less intense this time!

Swim Report – January 28, 2018 – Blazing Cold

The warmer temperatures this week eliminated all the ice and snow around our world famous swim site, so we had a clear area to swim in at 7:00am. Plus, for the first time in a while, we didn’t have a pesky cloud wall on the eastern horizon delaying the appearance of Mr. Sol!

From what I’ve read online (and the Internet is always right), the Earth is closest to the sun in January. So that would account for the super-intense sunshine we had to “tolerate” during our swim today.

The air temperature was a bit crisp at 34F, but the lake came in at a rather tepid 35.2F. Plus it was relatively calm – at least when we started.

I climbed down the ladder and eased into the lake, hoping that all this bright sunshine would take the edge off of the chilly water. Unfortunately, there is no way you can make 35.2F comfortable on your exposed skin. So I had to endure about 3-4 minutes of “pins and needles” on my forearms and legs before I finally acclimated to the lake conditions.

I’ve been doing more strength training since the holidays, and that has boosted my endurance a bit. So I was able to do 1/2 mile for the first time in a while. However, the return swim was a bit of a bear as the chops had intensified. Plus it didn’t help that I had been blissfully unaware of a rather vigorous southbound current that I had to swim directly into on that way back to L1!

Because of the extra time I spent in the water, my afterdrop was significantly more intense. So by the time I made it to the sanctuary of my heated Mazda, I felt like I was at the epicenter of a magnitude 8 quake. But fortunately for me, the worst of the tremors subsided by the time I got on the Kennedy!

All in all, yet another winter adventure out at the world’s greatest swim spot!

Swim Report – January 20, 2018 – Positive Wind Chill Edition

Four of us met out at L1 shortly before sunrise on Saturday. Unlike the past two weekends, the air temperature was mercifully mild this time (a very manageable 30F).

L1 was covered in a thick layer of ice which required some handiwork from the pick ax. But I waited until we were ready to get in the lake before hacking it off as it was rather striking looking in the clear morning sun!

The in-swim water temp came in at 33.2F – a slight improvement over two weeks ago. But with clear skies, no wind, and some very intense sunshine, the lake was actually quite amenable to our year-round magnificent obsession.

In what is now my new winter setup, I went with the double layer short sleeve top, shorts, hood, gloves, and booties and was able to do 1/4 in total. I could have done much more, but I had an early morning appointment up north, so I had to hustle back to L1 and abscond the premises prematurely.

Too bad I had to leave so soon – it turned out to be a very pleasant morning at our favorite swim spot!

(Non) Swim Report – January 13, 2018 – Icy Swells

L1 was a total bust this morning. The lakefront path was completely shut down due to the ice from yesterday’s monster waves. While the lake had settled down a bit by 7:00am, we still had some very high volume swells that “closed the pool” for the day.

But it was a good morning for pictures!

Swim Report – January 6, 2018 – Happy 2018!

The first official OWC swim of 2018 proved to be quite a challenge – and not just because of the 32.1F lake and 7F air temperature!

I arrived at L1 and was quite delighted to see that the lake itself was not completely frozen over. There were some slushy patches around the 1/2 mile point, but the area around L1 was completely clear. The only issue involved lake access.

The deep freeze over the past two weeks had taken its toll on the shoreline with everything shellacked by a thick layer of ice that had completely encased the lower part of all the ladders. So there was really no way to safely enter or exit the lake unless one had some special equipment.

Fortunately, I just happened to have a spare pick ax in my car for just such occasions…

It is no exaggeration whatsoever that clearing L1 was the most difficult, strenuous, and challenging task of the morning – even more so than swimming in the freezing lake. In total, it took about 40 minutes of continual hacking to finally free up the area. So by the time I was done with all this pre-swim labor, I had already gotten quite a cardio workout!

Taking advantage of my already warmed up state, I quickly donned my gear and got into the lake. I was wearing my usual neoprene setup – hood, gloves, booties, and a short sleeve top and shorts. But I also had a short sleeve thermo rash guard underneath my top which really made a difference in my overall comfort level.

The swim start was surprisingly easy as I was already very warmed up. Also, the lake was a scorching 32.1F – much, much warmer than the 7F air. So believe it or not, it was actually much more pleasant to get in the water than to stay outside on land!

I made it to the fourth ladder, just under 1/8 mile, before I ran into an impenetrable field of slush. This had all started to move in from the south, and there was no open water beyond that point. So I turned around and headed back.

Post-swim wasn’t as difficult as it has been in previous weeks. Even though the air temperature was pretty bracing, there was no wind at all, and we had a clear and sunny morning. So this really helped temper things while I was changing back into my dry clothes.

Happy 2018!

Swim Report – December 23, 2017 – Happy Winter!

Four of us met out at L1 for our first official winter meetup, and it was a rather brisk morning out at the old’ swim site. But not enough to keep us out of the lake!

The water temp came in at an estimated 36F, but the air temp was a chilly 30F with intermittent gusts from the southeast that sliced into my exposed hands while I was changing into my swim gear. We made short work of the pre-swim prep and quickly got in the lake. The initial immersion was a bit bracing, but not as agonizing on my exposed skin as last week – hence my assertion that the lake was a degree or two warmer than last Sunday.

I made it to the 1/8 mile post before turning around. The way back was a bit more challenging as the swells seemed to have picked up a bit, but I managed to make it back to L1 relatively unscathed.

Given that I had to be back home by 8:15, I decided to splurge and park at the NAB lot. So I was spared the tortuous trek back to Clark Street and instead got to the sanctuary of my heated car after only a short sprint.

You have to appreciate the little things this time of year!

Swim Report – December 17, 2017 – Ice Monster Territory

The lake was a bit more agitated this week, so I couldn’t get an accurate surface temperature with my pool thermometer. The reading came in at 39F, which we all agreed was likley way overstated. So the four of us geared up right away and eased into the lake – with the 2-3 foot swells continually reminding us of who was at the top of the dominance hierarchy.

I waited (waded?) in the water around L1 for a few minutes until the sharp stinging on exposed areas of my arms and legs finally subsided a bit. But since it never really stopped altogether, I figured I had best just get the swim started and hopefully get some relief along the way.

The in-swim mercury red 35.2F, and it sure felt like it! Fortunately for us, the air temperature was a furnace-like 37F, so we had some relief post swim.

I did just over 1/4 mile, a bit less than usual as my finger tips were really starting to get uncomfortably cold. I’ve had these gloves for at least 4 years, so I took this as a sign that they are now overdue for a replacement.

Having learned my lesson from last week, I got out of my swim gear and into my dry clothes much quicker this time thanks to my choice of looser fitting garments. Because of my rather minimalist winter swim setup in the lake, I experienced a rather intense afterdrop that took about 20 minutes to subside.

However, I was fortunate enough to have found a parking spot on Astor Street just on the other side of the pedestrian tunnel. So it was just a short, mad sprint to the comfort of a heated car.

I’ll take a quick win wherever I can get it this time of year!

The last swim of Autumn 2017!

Swim Report – December 10, 2017 – Into the Basement

People sometimes raise an eyebrow whenever I tell them that it’s actually much more difficult to swim in December than it is in January. The reason for this is that you have to overcome tremendous physical and psychological resistance this time of year – all internally generated by a brain that seems hell bent on keeping you out of the water by any means necessary.

Eventually, though, your repeated forays into the harsh elements send a strong signal to your stubborn noggin that “the beatings will continue until morale improves.” So at that point – usually some time in early to mid January – the role of your brain transitions from “let’s keep this tomfool out of the water” to “let’s preserve this tomfool in the water – since he’s obviously continuing a pattern with no apparent end in sight.”

We haven’t quite made it to the second phase yet, so yesterday’s swim was most certainly a challenge…

Last weekend’s mild temperatures turned out to be very short-lived as Old Man Winter decided to show up early and make himself at home right at L1. Yesterday’s air temperature at 7:00am was a biting 26F, and the surface lake temperature shattered the 40F floor, coming in at a bone cracking 38.1F.

But four of us still made the pilgrimage out to our coveted swim spot. So for better or worse, we were committed to getting in a swim!

I went with my neoprene winter gear set up from last year – short sleeve top, shorts, hood, gloves, booties – along with overly generous portions of shea butter on my exposed forearms, legs, and face. But even with all this layering, it was still pretty harrowing for the first couple of minutes in the lake.

By the time I had reached the 1/8 mile point, everything was fine. The only glitch was that my right goggle lens was leaking a bit, giving my right eye a constant cold water soaking with every swim stroke. So while I could have done a full 1/2 mile, I turned back and ended up with just under 1/3 mile like last week.

Post-swim was the big challenge as I had not planned my wardrobe well. Instead of loose fitting sweats, I had opted for running tights that proved to be very difficult to put on with frozen clubs for hands. Bottom line, it took a bit longer that usual to get into my warm civilian clothes – and every second is critical this time of year!

The walk back to the car was a quasi-fugue state as the afterdrop started to ramp up before I even entered the pedestrian tunnel on the other side of the bike path. It didn’t help that I wasn’t able to find parking closer than Clark Street. So I was incredibly relieved when I finally got in my car and cranked up the heat.

It took about 15 minutes before the shivering reduced to a level amenable to operating a motor vehicle. But when it was gone it disappeared for good.

So hopefully I’ve sped up the acclimation process this season!

Swim Report – December 3, 2017 – Heat Wave

I made it out to the lakefront about 20 minutes before sunrise, and there were already photographers set up all along the North Avenue Beach wall. That’s a sure sign that there’s going to be a spectacular sunrise. And Ma Nature certainly did not disappoint!

Five of us congregated out at L1, and the swimming conditions couldn’t have been better with a perfectly flat lake and a surface temperature reading of 44.4F – up more than 3.0F from last week. Plus the clarity of the water had improved significantly, an indicator that the lake had completely turned over and was now sporting a new winter layer on the surface.

I debated going in without my neoprene top, but I decided to wear it as I’d been fighting off a pretty nasty cold all week. But I probably could have gone without it as I was very comfortable the entire time in the lake. This just goes to show you what a difference it makes when we have no wind and abundant sunshine!

I ended up doing 1/3 mile total and stopped several times during the swim to get some water level shots as it was quite a photogenic morning. I had a bit of an afterdrop when I got out, but certainly nothing compared to last week. By then the air temperature had risen to about 48F, so it was a pretty easy transition back to normalcy.

I wish all December swims could be like this!
