Cold-water diving may not be for everyone but it does offer some pretty memorable opportunities. It’s defined as diving below 15°C. Cold-water diving is remarkable because it tends to have nutrients from upwellings which leads to more marine life. Wrecks tend to be better maintained in cold-waters making them some of the most popular cold-water diving destinations in the world.
Being properly prepared is essential for cold-water diving. One of the aspects to consider with cold-water diving is the type of regulator you will use. You will usually have two valves, in case one of the valves or first stages has an issue.
Cold-water diving requires special equipment. Get dry-suit certified to make the cold water more manageable. Dry-suits require special care and attention. To keep warm get an undersuit and layer thermals on top depending on the temperature and where you dive.
Cold-water diving takes preparation, both the water and outside temperature can be below freezing making it important to have the right equipment. Bring extra layers to put on before and after dives. Ski gear is effective. Hats, gloves and socks are also good investments. This simple act helps to conserve your body’s heat. You want to be as warm and comfortable as you can before you start diving. Quickly change in-between dives to not lose any further body heat.
Bring a container of hot water that you can soak your gloves and hood in before you start the dive. You don’t have to use your energy to heat them up during the dive. Replenish your liquids with hot beverages in between and after dives.
For those that dive in cold-water on the regular, there are heated vests which work to keep your torso warm and toasty. They are worth the investment. Try to keep your extremities warm during the dive. Wearing gloves and socks underneath your dry-suit can help. When starting out, do shorter dives while you get accustomed to the temperature. Practice with new gear and get a feeling for diving in cold-water. Don’t push your limits, this is a general rule with scuba diving but should be a special consideration with cold-water diving. Doing some stretching before the dive can help warm up your body.
Cold-water is home to some amazing species that you may not get the chance to see if you only dive in warmer waters. Practice skills while wearing gloves in preparation of diving in cold water. If you feel too cold, be sure to cancel the dive. At any point if you start to find it uncomfortable or difficult to breathe, end the dive.
