Coping with Dropping Water Temperatures | Swim the Lochs Safety Guide

Coping with Dropping Water Temperatures

As the seasons shift and water temperatures fall, wild swimming becomes a different kind of adventure. The water feels sharper, recovery takes a little longer, and safety becomes more important than ever. But with good preparation, the colder months can be some of the most rewarding to swim in.

Here are my five tips to help you adapt, enjoy, and stay safe as the temperatures dip:

1. Acclimatise
Keep dipping as the water cools. Short, regular swims help your body adjust naturally and reduce the shock of sudden temperature changes. Consistency really is your best friend.

2. Check Conditions
Before you get in check the weather, water temperature, and wind. Remember, it’s not just the water that chills you — wind can make warming up afterwards much harder.

3. Limit Your Time
Cold water swimming isn’t a test of endurance. It’s about leaving the water feeling strong, safe, and in control. As the temperatures drop, your swim time should shorten accordingly. And forget the “1 minute per degree” rule — it’s a dangerous myth and not a safe guide for outdoor swimmers.

4. Layer Up
Have your post-swim kit laid out and ready. Start warming your core first with dry, cosy layers, then add a hat, gloves, and something warm on your feet. Don’t hang around in wet kit — warmth first, chat later!

5. Never Swim Alone
Cold water increases the risks of disorientation, muscle weakness, and hypothermia. Always swim with a buddy or make sure someone is watching from the shore. A warm drink and a small snack afterwards are the perfect finishing touch.

The colder months can offer the most magical swims — crisp air, calm waters, and a huge endorphin boost. Respect the conditions, prepare well, and you’ll be able to enjoy every dip safely.

Swim your own swim.

Don’t stay in longer just because someone else can.

The water will always be there another day.

If in doubt, sit it out.

Stay safe and enjoy the cold.
