The single most important decision in kayaking gear is not your kayak, it is what you wear in it. Every year paddlers capsize in cold water wearing only board shorts and a t-shirt because the air was warm. Water pulls heat from your body about 25 times faster than air at the same temperature. If the water is cold, your clothing needs to reflect that, not the weather forecast.
This guide covers wetsuits for kayaking specifically: when you need one, how to choose the right thickness, the difference between a wetsuit and a drysuit, and what works for different paddling conditions. The keyword searches “wetsuit for kayaking in winter” and “best wetsuit for kayaking cold water” both point to the same underlying question: what water temperature requires what gear?

Do you need a wetsuit for kayaking?
The standard guide used by most paddling instructors is the 60/120 rule. Add the air temperature and water temperature together. If the combined number is below 120 degrees Fahrenheit, wear a wetsuit or drysuit. If the water alone is below 60 degrees Fahrenheit, wear a wetsuit regardless of air temperature.
At water temperatures between 60 and 70 degrees, a 3mm wetsuit is the most common recommendation. It provides meaningful thermal protection while still being comfortable in air temperatures above 60 degrees. Below 60-degree water, a 5mm wetsuit or a drysuit is more appropriate. Above 70-degree water with air temperatures in the 80s, a wetsuit is optional, sun protection and quick-dry clothing may be all you need.
Wetsuit thickness guide for kayaking
Wetsuit thickness is measured in millimetres. A wetsuit described as 3/2mm has 3mm of neoprene through the torso and 2mm through the arms and legs for mobility. The thicker the neoprene, the warmer the suit and the more restricted your arm movement will be, which matters a lot when you are paddling for hours.
2mm full suit or shorty: Water above 70 degrees Fahrenheit (21 Celsius). Good for spring and autumn paddling in mild climates when the water is still cool from winter but air temperatures are warm.
3mm full suit: Water between 60 and 70 degrees Fahrenheit (15-21 Celsius). This is the most versatile thickness for three-season paddling in temperate climates. It covers most of what recreational sea kayakers and touring paddlers encounter.
5mm full suit: Water between 50 and 60 degrees Fahrenheit (10-15 Celsius). Cold-water paddling, winter sessions in mild climates, or spring paddling in regions where water temperatures stay low into June.
Drysuit: Water below 50 degrees Fahrenheit (10 Celsius). A drysuit seals at the wrists and neck and keeps water out entirely. You layer thermal undergarments inside it. Drysuits are the standard for winter paddling, Arctic expeditions, and whitewater in cold climates. They are expensive (quality drysuits run $800 to $2,500) but they are the correct tool for genuinely cold conditions.
Full suit vs shorty wetsuit for kayaking
A full wetsuit covers arms and legs. A shorty has short arms and short legs, providing less coverage but more freedom of movement and better cooling in warm conditions.
For kayaking specifically, most paddlers prefer a full suit even in warmer water because the legs and lower back are constantly exposed to spray and splashes off the paddle. A shorty leaves your legs exposed to sun, cold water drips, and the seating surface of the kayak. Full suits also provide UV protection across a full day on the water.
The one situation where a shorty makes sense: warm-weather kayaking in water above 75 degrees where you want the thermal protection of neoprene but need to manage body heat on long paddles.
Wetsuit fit for kayaking
A wetsuit works by trapping a thin layer of water between the neoprene and your skin. Your body heats that water, and the neoprene insulates it. For this to work, the suit must fit snugly, there should be no gaps at the wrists, ankles, or neck, and no air pockets across the back or chest.
At the same time, a wetsuit that is too tight restricts breathing and paddle strokes. Try raising both arms overhead before buying, you should be able to do this without the suit pulling at the shoulders. The crotch of the suit should sit comfortably against your body, not hanging loose.
Wetsuit sizing varies significantly between brands. Always size from the manufacturer’s size chart using your chest, waist, and height measurements. Do not assume your size in one brand carries over to another.
Wetsuit for sea kayaking vs river kayaking
Sea kayaking and river kayaking have different wetsuit needs. Sea kayakers typically paddle long distances in exposed conditions where water temperature and wind chill are the primary concerns. A 3mm full suit with neoprene booties and gloves covers most conditions. On multi-day coastal expeditions, many sea kayakers use a drysuit even in summer because they cannot afford to be cold and wet all day.
Whitewater kayakers swim regularly, it is a normal part of the sport in difficult rivers. They need suits that provide protection during swims over rocks as well as thermal insulation. A 3mm farmer john (no arms, allowing paddling freedom) worn over a neoprene top is a common whitewater combination. The layered approach lets you adjust for conditions throughout a session.
Wetsuit pants for kayaking
Wetsuit pants are worth considering for paddlers who run warm on top but want leg protection. They work well under a paddling jacket in conditions where you need some thermal protection but a full wetsuit would be too hot. Neoprene pants are also commonly worn by kayak anglers who want leg warmth without the restriction of a full suit on a long fishing day.
Neoprene booties deserve specific mention. Cold feet affect your entire experience on the water and your ability to feel the footpegs. Neoprene booties in 3mm or 5mm thickness, with a rubber sole for walking on slippery rocks and boat ramps, are worth adding to any cold-water paddling kit.

FAQ: wetsuit for kayaking
What thickness wetsuit do I need for kayaking?
Use water temperature as your guide. A 3mm full suit covers water between 60 and 70 degrees Fahrenheit (15-21 Celsius), which is the most common range for three-season paddling. Below 60 degrees, use a 5mm suit or drysuit. Above 70 degrees, a 2mm suit or just UV-protective quick-dry clothing may be sufficient depending on conditions.
Should I wear a wetsuit or drysuit for kayaking?
A wetsuit is the right choice for water between 50 and 70 degrees Fahrenheit. A drysuit is better for water below 50 degrees, winter paddling, or extended expeditions where staying dry matters more than insulation alone. Drysuits cost significantly more but are the safest option in genuinely cold conditions.
Can I wear a surfing wetsuit for kayaking?
Yes, with caveats. Surfing wetsuits work fine for thermal protection. The fit may be slightly different, surfing suits prioritise flex through the hips and knees for paddling out and popping up, while kayaking suits need more flex through the shoulders and upper torso for paddling. A surfing wetsuit that fits well and allows your arms to move freely overhead is perfectly usable for kayaking.
Do women need a different wetsuit for kayaking?
Women’s-specific wetsuits are cut differently through the hips, chest, and torso. They fit better and provide better thermal protection because a correctly-fitted wetsuit traps water more evenly. Women paddlers should use women’s-specific sizing rather than sizing down in a men’s suit, which usually leaves gaps at the neck and lower back.
