While many across the country face bitter winter conditions, Southern Californians enjoy comparatively mild winter weather. Average air temperatures hover around 60 degrees Fahrenheit during the day and drop to the 40-50 degrees Fahrenheit range in the evening. Water temperatures remain around 55 degrees Fahrenheit. Yet for locals accustomed to sunshine, even these relatively mild temperatures can feel quite cold, especially when out on the water. For boaters, staying warm and comfortable during the winter months requires thoughtful preparation, layered clothing and equipment to ensure safety and enjoyment. Here are some practical tips to help Southern California boaters stay warm in what feels like “cold weather” on the water.
Layering is one of the most effective ways to stay warm in fluctuating winter conditions. Boaters know how quickly temperature can shift when out at sea, especially when the wind picks up and the sun begins to set. A well-constructed layering system will help manage body heat, regulate moisture, and block wind and water. Start with a high-quality base layer made from moisture-wicking material like merino wool or synthetic fibers, which help keep sweat away from the skin and ensure you stay dry. Popular brands like Smartwool and AFTOC offer options for base layers. Merino wool is particularly effective because it keeps you warm even when wet and is naturally odor-resistant, making it ideal for long days on the water.
Next comes the insulating layer. This is where you trap warmth while allowing your body to breathe. Fleece and wool are both fantastic insulating materials. A fleece jacket or mid-layer like Guy Cotten’s “OTTER” Jacket or the Denali Top will offer lightweight warmth without feeling bulky. If you prefer wool, Icebreaker and Smartwool also offer mid-layer sweaters designed for outdoor activity that provide excellent warmth and comfort. Grundéns’ Transmit X Jacket tends to be a crowd favorite because it is made of 100% Nylon 15K/10K Waterproof with a breathable performance.
The outer layer is essential for protecting you from wind and water, which can make even mild temperatures feel much colder. A waterproof and windproof jacket will keep you dry and block those biting gusts that seem stronger on the water. Look for jackets specifically designed for boating, like Helly Hansen’s Salt Coastal Jacket or Gill Marine’s OS3 Coastal Jacket. These jackets are made from breathable materials, preventing you from overheating while ensuring you remain dry even in heavy sea spray. Features like high collars, adjustable cuffs and storm flaps also will help keep you warm by sealing out the elements.
Deckhand gloves are essential for keeping boaters and anglers warm during the winter months by providing insulation and protection against the elements. These gloves are designed to be water-resistant, preventing cold water from reaching your hands and they often include thermal lining to trap heat. Their durable materials and reinforced grips also allow for dexterity in wet, slippery conditions, making them perfect for handling ropes, fishing gear and steering without losing warmth or functionality.
Don’t forget your extremities. Heat is lost quickly through the hands, feet and head, so keeping them protected is crucial. Waterproof gloves are essential, especially if you’re handling ropes, steering the boat or dealing with fishing gear. Gill Marine’s Deckhand Gloves or Musto’s Performance Winter Gloves are excellent choices that offer both insulation and dexterity. For the feet, insulated, waterproof boots are a must. Xtratuf’s Legacy Boots are a favorite among boaters and anglers alike, offering warmth, waterproof protection and a slip-resistant sole perfect for slippery decks. Pair these boots with moisture-wicking, thermal socks like Darn Tough or Icebreaker to keep your feet dry and warm.
A good beanie or balaclava will also make a world of difference. You lose a significant amount of body heat through your head, so keeping it covered is essential, especially on windy days. A wool beanie from Patagonia or Outdoor Research offers warmth without itchiness and a balaclava can offer extra face protection during particularly cold days at sea.
For boaters with enclosed cabins, investing in safe heating equipment can make longer outings much more comfortable. Caframo’s True North Heater is a marine-safe electric heater designed specifically for boats, offering powerful yet quiet heat that is safe to use in enclosed spaces. Portable propane heaters, while effective, pose a carbon monoxide risk, so it’s essential to only use those that are designed for marine use and to ensure proper ventilation. Diesel heaters, like those from Webasto or Espar, are also excellent options for boaters looking for a more permanent heating solution. These heaters run on diesel fuel and provide consistent, reliable heat, which is ideal for longer trips or cold mornings on the water.
Diesel heaters can be safe on boats if installed and maintained correctly, but improper installation poses serious risks such as fire and carbon monoxide poisoning. Professional installation is recommended, especially if you’re not experienced. It’s important to use high-quality heaters and ensure proper ventilation by opening a window or vent when running the heater overnight. Install carbon monoxide detectors in each cabin, keep fire extinguishers on board and have a safe exit plan. Additionally, insulate any combustible materials near the heater and store extra fuel in a well-ventilated compartment.
Another critical aspect of staying warm is staying dry. Even a small amount of water or moisture can cause a rapid loss of body heat, so it’s essential to stay as dry as possible. Carrying a dry bag on board can help ensure you have spare clothing in case you get wet. YETI’s Panga Dry Bags or Sea to Summit’s Hydraulic Dry Bags are popular options for keeping your extra layers or valuables completely dry, even in rough conditions.
In addition to clothing and equipment, other small but important considerations can go a long way in keeping you warm. Having a thermos of hot drinks on hand can provide a quick burst of warmth. Stanley’s Classic Vacuum Bottle or Hydro Flask’s Insulated Bottle will keep coffee, tea or hot chocolate piping hot for hours. Plus, sipping on a hot drink helps maintain core body temperature, especially when temperatures drop during the early morning or late afternoon.
Keeping your energy up is also essential. High-calorie snacks like nuts, granola bars or trail mix are perfect for providing quick, long-lasting energy, which in turn helps your body stay warm. Packing hot meals in an insulated container can make a big difference when you’re on a long boating trip. A hot bowl of soup or stew will warm you from the inside out.
Another essential aspect of boating during colder months is staying mindful of the weather forecast. Winter can bring unpredictable weather and even Southern California’s mild winters can sometimes produce storms or rough seas. Be sure to check the forecast before heading out and always have a plan for returning to shore quickly if the weather takes a turn for the worse. Additionally, remember that days are shorter in winter, so plan your outings accordingly to avoid being caught on the water after dark when temperatures can drop significantly.
Though we are fortunate to have relatively mild winters in Southern California, being out on the water in colder temperatures requires preparation. Layering with high-quality clothing, investing in marine-specific outerwear, protecting your extremities and ensuring you have the right equipment on board can make all the difference between a chilly, uncomfortable trip and a pleasant day out on the water. Staying dry, drinking hot beverages and keeping an eye on the weather will also ensure you stay safe and warm during the colder months. With the right preparation, Southern California boaters can continue to enjoy their time on the water all year round, even in what we consider “winter” weather.
