Does Wetsuit Color Matter For Warmth?
Lauren April 28th, 2025 Posted In: Articles
When it comes to wetsuits, fit and wetsuit thickness are usually the first things people think about for staying warm. But what about color? Does wetsuit color matter for warmth? In short, yes — but not in a way that’s likely to dramatically impact your comfort during most water activities.
While darker colors, like black, can absorb more heat from the sun and slightly help with warmth, the difference is minor compared to factors like neoprene thickness and fit. That said, color can still play a role in specific situations, and it’s definitely worth diving deeper into the details below!
Understanding Wetsuit Color and Warmth
The primary purpose of a wetsuit is to trap a thin layer of water against your skin, which your body warms up. This warm water layer acts as insulation. The material (usually neoprene) and the thickness of your wetsuit are the biggest factors for maintaining warmth. So, does wetsuit color matter for warmth? Technically, yes — but it’s not the star of the show.
Darker colors, like black, absorb more sunlight. Black wetsuits can soak up more UV rays, potentially giving you a slight warmth boost when you’re exposed to direct sunlight. On the flip side, lighter colors reflect sunlight, which might actually help you stay a bit cooler if you’re out in a hot, sunny climate. Still, these effects are fairly marginal. If you’re fully submerged, sunlight absorption won’t make much of a difference because water absorbs and disperses sunlight quickly.
Why Are Most Wetsuits Black?
It’s no accident that black is the dominant color in wetsuit design. Not only does black absorb heat, but it also has practical benefits. Neoprene is naturally off-white, but it’s dyed black to improve its UV resistance and durability. Black wetsuits last longer, resist staining, and look sleek. This might explain why you’ll notice surfers wearing black wetsuits most of the time!
Factors That Matter More Than Color
When it comes to warmth, several factors outweigh the effect of wetsuit color:
- Neoprene Thickness: A 5mm wetsuit will always be warmer than a 2mm wetsuit, regardless of color.
- Wetsuit Fit: A snug wetsuit fit prevents cold water from flushing in and out, helping to retain warmth.
- Wetsuit Features: Elements like sealed seams, thermal linings, and integrated hoods can make a huge difference in heat retention.
- Activity Level: The more you move, the warmer you’ll stay, no matter what color your wetsuit is.
Simply put, if you’re freezing in a thin, ill-fitting wetsuit, painting it black won’t solve the problem!
Is There a “Best” Wetsuit Color for Warmth?
If you’re really trying to maximize every bit of warmth, going with a black or dark-colored wetsuit is your best bet. Black absorbs and retains heat from the sun better than lighter colors. Dark colors resist fading and UV damage, helping your suit stay strong and effective over time. Plus, darker suits are less likely to show dirt, stains, or wear and tear — important if you’re diving, surfing, or paddling in challenging environments.
That being said, if you love the idea of a colorful wetsuit, don’t stress! Most of your warmth will still come from your wetsuit’s material, fit, and features, not its color.
When Wetsuit Color Might Matter More
There are specific instances where wetsuit color could be slightly more important:
- Surface Activities: If you’re spending a lot of time on top of the water, like surfing or paddleboarding, a black wetsuit might keep you a tad warmer.
- Cold, Sunny Conditions: In sunny but chilly conditions, a darker wetsuit might offer a minor edge in comfort.
- Long Surface Intervals: For divers, long periods at the surface between dives could make color slightly more relevant for warmth.
However, as mentioned earlier, if you’re primarily submerged, color becomes less important because sunlight doesn’t penetrate deeply into the water.
Other Benefits of Choosing Wetsuit Color
Beyond warmth, the color of your wetsuit can impact your experience in other ways. Bright wetsuits can make you more visible to boats or fellow divers, which is a safety perk. Choosing a colorful wetsuit also lets you show off your personality while hitting the waves! Additionally, some marine life reacts to colors. In certain regions, darker or neutral tones might be better if you’re trying to blend in and observe wildlife.
Wetsuit Color Warmth: Choose What’s Best for You
So, does wetsuit color matter for warmth? In short, it does—but just a little. Darker colors like black can absorb more sunlight and provide a slight warmth boost when you’re above the surface. However, factors like neoprene thickness, wetsuit fit, and additional thermal features are far more crucial for keeping you warm in the water.
If you’re shopping for your next wetsuit and warmth is your top priority, focus on thickness, fit, and construction first. Color is simply the cherry on top. And if you want to go with a vibrant wetsuit to stand out or stay safer, go for it! Your comfort and style can coexist in the water.
