Winter Wetsuit Guide 2026: Everything You Need to Stay Warm Longer
7 min reading time
Autumn is here. The air is getting fresher, the water is cooling down and your summer suit is starting to feel a little thin. But that doesn't mean the sessions have to stop. With the right wetsuit, the best rides of the year are still ahead. Here's everything you need to know.
How does a wetsuit actually work?
A wetsuit works by trapping a thin layer of water between your body and the suit. Your body heats that water, and the neoprene keeps it warm, even in cold conditions. The key is stopping that layer from flushing out when you crash or wipe out. Cold water flushing in forces your body to reheat it constantly, which drains your energy fast. That's why fit, seams and material all matter more in winter than in summer.
The right wetsuit thickness depends on water temperature. Here's the breakdown, based on what our team rides and what the leading brands recommend:
4/3 wetsuit: water temp 12°C–17°C. The in-between suit. Ideal for early autumn and those days when the water is cooling but you're not ready to go full winter yet. Shop 4/3 →
5/4 wetsuit: water temp 8°C–12°C. The Dutch winter go-to. From late autumn through winter and into early spring, this is what most riders at the Brouwersdam ride. Shop 5/4 →
6mm wetsuit: water temp below 8°C. Maximum warmth for the coldest days, long sessions and anyone who gets cold easily. When the North Sea is at its most brutal — this is your suit. Shop 6mm →
Kitesurfer or wingfoiler? You're in the wind constantly, which makes you feel the cold harder than a surfer sitting in the water. Many riders at the Brouwersdam go one step thicker than the chart suggests, especially when that north wind is blowing. Not sure what's right for your sessions? Come by the shop and ask the team.
Features that actually make a difference
Seams
Seams are where cold water sneaks in. The better the seam, the warmer you stay.
GBS (Glued and Blind Stitched): panels are glued and stitched halfway through the neoprene. 95% waterproof and the standard for a good winter suit.
GBS + Fully Taped: adds a flexible tape on the inside of all seams. More durable, better sealed and extra insulation where it counts.
Liquid Seams: a liquid rubber is applied to the outside of the seam after stitching. Nearly 100% waterproof. The best option for cold, rough conditions.
Inner lining
The inside of your wetsuit matters as much as the outside. A good lining adds insulation, dries faster and keeps you comfortable during those moments when you're not moving — waiting for the next set, drifting upwind or taking a break on the beach.
Halo X2 (C-Skins): quick-drying, lightweight and comfortable against the skin
Flash Lining (Rip Curl): one of the fastest-drying linings on the market. Plush, warm and moisture-managing
Magma Fleece (Manera): soft, warm and insulating. Dries fast and keeps you comfortable through long sessions
Neoprene type
Not all neoprene is the same, and in cold, windy conditions the difference is very noticeable.
Single lined / smooth skin neoprene: doesn't absorb water and blocks wind chill. Essential for kitesurfers and wingfoilers who are constantly in the wind
Double lined neoprene: great stretch and durability, but doesn't block wind. Less effective when it's cold and gusty
What kind of zip is easy to use?
Most riders know the difference between a back zip and a chest zip, but there's a newer option worth knowing about: the U-zip entry system.
A U-zip entry runs in a U-shape across the chest and shoulders, combining the easy entry of a back zip with the warmth and flexibility of a chest zip. Less water intrusion than a traditional back zip, easier to get in and out of than most chest zip systems.
In summer, a small gap is annoying. In winter, it means cold water flushing straight in. Your winter wetsuit should feel like a second skin: snug around your neck, wrists and ankles, with no loose folds at your lower back or under your arms.
Since sizing varies across brands, always check the specific size chart or ask our team for help finding the right fit.
What else do you need?
Your wetsuit is only half of your winter setup. The water temperature determines not just which suit you need, but which accessories make the difference between a good session and cutting it short.
From 12°C and below: boots Cold feet end sessions fast. Winter boots are thicker and warmer than summer booties, keeping you comfortable and grounded on your board or foil. New in: the C-Skins Nuwave boots: a warm fit with great feel underfoot. Shop winter boots →
From 10°C and below: gloves Once the water drops below 10°C, cold hands affect your grip on your bar, boom or rails. Gloves keep your hands warm and your control sharp. Shop gloves →
From 8°C and below: hood You lose a significant amount of body heat through your head. At 8°C and below, a hood is no longer optional, it's what keeps you out there longer. Many 5/4 and 6mm suits come with an integrated hood; if yours doesn't, a separate hood makes a big difference. Shop hoods →
All season: poncho The coldest part of a winter session is often after you get out. Wind on wet skin cools you down fast. A poncho lets you change on the beach quickly and warm up straight away, a must-have at the Brouwersdam in autumn and winter. Shop ponchos →
All season: wetsuit care To keep your winter suit performing all season, rinse it after every session and use wetsuit shampoo regularly. A well-maintained suit lasts years longer. Shop wetsuit care products →
Stay warm after your session
The coldest part of a winter session is often after you get out. Wind on wet skin cools you down fast — throw your poncho on straight after, change quickly and warm up in minutes.
Even better: come warm up at the Dam. Drop by for a hot chocolate after your session. Keep an eye on our Instagram to see when we're open.
Before your summer suit goes to sleep
Give your summer wetsuit the care it deserves before storing it. Rinse it with wetsuit shampoo, check the seams and zippers and repair anything that needs attention. A clean, well-maintained suit is ready to go the moment summer comes back.
