As temperatures drop and the days get shorter, wild swimming in autumn and winter becomes an exhilarating challenge for those who love the thrill of cold water. The crisp air, misty landscapes, and the refreshing shock of icy water create a unique and rewarding experience for outdoor enthusiasts. However, swimming in cold water comes with risks, making safety and preparation more important than ever.
If you’re planning to take a dip in lakes, rivers, or the ocean during the colder months—or even pair your swim with a paddleboarding adventure—it’s essential to be mindful of the specific challenges that come with colder conditions. Here’s how to enjoy wild swimming safely in autumn and winter.
1. Dress for the Water, Not the Air
When preparing for wild swimming in colder weather, one of the most important rules is to dress appropriately for the water temperature, not just the outdoor air. Even if it feels chilly outside, water temperatures can be much colder, and hypothermia is a real risk.
For autumn and winter swims, a wetsuit or drysuit is recommended to provide insulation and protection. Wetsuits made from neoprene trap a thin layer of water between your body and the suit, which your body then warms up, helping to regulate your temperature. A drysuit, on the other hand, keeps you completely dry and is ideal for extremely cold water.
When paddleboarding in cold conditions, wearing a wetsuit or drysuit is just as important since falling into icy water can cause your body temperature to plummet quickly. No matter which activity you choose, investing in proper thermal gear will help keep you safe and comfortable.
2. Ease Your Body Into Cold Water
Suddenly immersing yourself in cold water can shock your system, so it’s essential to ease in slowly. If you’re new to cold-water swimming, start by dipping your toes or wading into the water rather than diving straight in. This allows your body to gradually acclimate to the colder temperature, reducing the risk of cold water shock, which can cause hyperventilation and panic.
Take deep, controlled breaths as you enter the water to help your body adjust and avoid the urge to gasp when you feel the cold. The first few minutes in cold water are always the hardest, but once your body adapts, you’ll find the experience invigorating.
For regular cold-water swimmers or paddleboarders, try to swim frequently, even if it’s just for short sessions. Consistency helps your body adapt to lower water temperatures more effectively.
3. Don’t Swim Alone
Safety in numbers is a key rule for wild swimming, particularly in cold water. Always swim with a partner or as part of a group to ensure that someone is nearby in case of an emergency. If you’re combining your wild swim with a paddleboarding session, having a friend who can assist you if you fall in or get too cold is equally important.
In case of an accident or sudden cold water shock, your partner can help you get out of the water quickly or provide warmth. Not only does swimming with others enhance safety, but it also adds to the shared experience, making the activity more fun and social.
4. Choose Safe Entry and Exit Points
Before entering the water, take the time to assess your surroundings and pick safe entry and exit points. The spot where you enter might look calm, but water currents can be deceiving, especially in rivers or near the ocean.
Look for gradual slopes or beaches where you can enter the water safely. Make sure that your exit point is equally accessible, as your limbs can feel numb after being in cold water, making it more difficult to climb out over rocks or steep banks.
If you’re paddleboarding, make sure to choose locations with easy access to the water and avoid strong currents or waves that can knock you off your board. Always wear a life jacket or personal flotation device (PFD) to ensure your safety on the water.
5. Know When to Get Out
Wild swimming in cold water can be exhilarating, but it’s crucial to know your limits. Cold water affects the body quickly, and staying in too long can lead to hypothermia. Early signs of hypothermia include uncontrollable shivering, numbness, and difficulty with coordination.
Even if you’re feeling great, set a time limit for your swim based on water temperature. As a rule of thumb, start with shorter swims (5-10 minutes) and gradually increase your time in the water as you acclimate over multiple sessions. Always listen to your body, and if you start to feel too cold or tired, exit the water immediately.
When paddleboarding, keep an eye on the weather and water conditions. If you start to feel cold or the wind picks up, head back to shore to avoid losing energy while paddling against stronger currents.
6. Bring the Right Gear
Having the right gear can make all the difference when swimming in cold water. Here’s a checklist of essential items to bring with you:
- Wetsuit or drysuit for warmth and protection
- Neoprene gloves and booties to keep hands and feet warm
- Swim cap or neoprene hood to reduce heat loss from your head
- Thermal socks for added warmth in colder conditions
- Towel and dry robe to dry off and warm up quickly after your swim
- Waterproof bag for keeping your dry clothes and gear safe from getting wet
If you’re paddleboarding, make sure to use a dry bag attached to your board, so your essentials stay dry even if you fall into the water.
7. Know How to Get Warm and Stay Warm
Once you’ve completed your swim, your body continues to lose heat rapidly. It’s critical to know how to get warm and stay warm as soon as you exit the water. Wrap yourself in a towel or dry robe immediately, and change into warm, dry clothes as quickly as possible. Bring thermal layers and a hat to cover your head, as heat is lost quickly from the scalp.
Drinking a hot beverage, such as tea or hot chocolate, will help to warm you up from the inside. Avoid alcohol, as it can actually make you colder by dilating your blood vessels and increasing heat loss.
8. Always Be Prepared for the Weather
Autumn and winter weather can change quickly, especially near water. Always check the forecast before you go swimming or paddleboarding, and be prepared for sudden temperature drops or rain. Pack extra clothing and blankets in your car or backpack, just in case you need them post-swim.
A waterproof backpack is an excellent investment for any outdoor adventure, as it ensures your gear stays dry even if the weather turns. Having a dry, warm set of clothes to change into after your swim is essential for keeping your body temperature stable and preventing post-swim chills.
Wild swimming in autumn and winter offers a truly refreshing and rewarding experience, but it comes with unique challenges. By following safety guidelines—dressing appropriately, swimming with others, and knowing your limits—you can enjoy the thrill of cold water while minimizing the risks. Whether you’re diving into a lake, swimming in the ocean, or paddleboarding alongside the shore, staying prepared is key to a successful cold-water adventure. Be sure to know how to get warm and stay warm after your swim to fully enjoy the experience and keep your body safe from the cold.
