Is a 3mm wetsuit good for swimming?
A 3mm wetsuit is ideal for UK summer months (June–September) when water temperatures range between 14–18°C, offering warmth and flexibility for surfing and swimming. You don’t need a wetsuit for open water swimming. However, without one in the UK, you will quickly become uncomfortably cold. So, if you are the sort of wild swimmer who dips in the water for 10-15 minutes to help support your cardiovascular system, then investing in a swim wetsuit might be counterproductive.So in theory not wearing anything that can interfere with that layer will make your wetsuit work more efficiently. Also wearing anything under an already tight-fitting wetsuit will reduce flexibility, so if you want the maximum range of movement in your wetsuit, it’s probably best to wear nothing under it.Whatever you use your wetsuit for, the most important thing to get right is the fit. Your wetsuit should feel snug and tight all over. If there’s excess material in places like the neck and cuffs, it will let water in and negate all its insulating properties. Don’t be too taken aback by the tightness of a wetsuit.Wetsuits should be close fitting to your body without any bagginess, while still being able to move your arms and legs comfortably. However, it shouldn’t be too easy to get on and off, if it is easily done without much effort, it may be too big.
How tight should a wetsuit be for swimming?
How tight should a swim wetsuit be? A wetsuit should fit as tightly as you can comfortably get into. What you need to avoid are slack areas where water can pool, or loose seals around the ankles, wrists, and neck. If your wetsuit is too loose, cold water will enter the suit freely or “flush through”. Fit: A wetsuit should be snug but comfortable. A too-loose fit will allow water to flood the suit, undermining its warmth, while a too-tight suit can be constricting and uncomfortable. Thickness: Wetsuit materials come in a range of finely tuned thicknesses.Buy a swimming specific wetsuit with the more continuous motion of swimming, all over thickness of the wetsuit for warmth is not required.

Improved Streamline – With better body alignment and buoyancy, you hold speed with less effort using less oxygen and energy at the same or faster paces.A wetsuit should fit like a second skin. It should feel tight but not restrictive, with no gaps in the nooks and crannies of your body such as under your arms, the lower back and behind the knees.

Coupled with heat, you can take a brand new wetsuit to completely destroyed in a matter of weeks.Graphene-infused neoprene: Graphene is 200 times stronger than steel and conducts heat exceptionally well. In 2025, this material is increasingly being used in wetsuits from brands like Rip Curl and Xcel. The result? Thinner, lighter suits that still retain exceptional warmth — perfect for cold surf spots.A 5mm neoprene thickness is ideal for water temperatures between 10°C and 15°C, offering warmth and a fair amount of flexibility for activities like surfing or diving. In warmer waters above 15°C, it may feel too warm, and a thinner wetsuit (3mm or 2mm) is a better choice.Neoprene Tops and Shorts A 1-2mm neoprene top and shorts will give a good extra layer of warmth, more so than thermals and will give your core extra protection.

But if you plan to tackle cold waters or winter waves, a 5mm wetsuit will keep you toasty and ready for anything. A 7mm is generally recommended for water temps between 50 and 70 F, but individual cold tolerance varies so dramatically that some will be fine at 50 and below even in a 5mm, while others will want a drysuit at 70. For me, in the local temperatures, a 5mm is not enough but a 7mm generally is.Many affordable wetsuits hold up just fine.

How to size a wetsuit for swimming?
Here’s how to achieve the ideal wetsuit fit: Snug but Not Restrictive: The wetsuit should fit snugly around your body without restricting your breathing or movement. If you feel constricted or unable to bend comfortably, the wetsuit might be too small. Just like above, we’d highly recommend that if you want to wet a wetsuit before putting it on, then make sure you’re wet too. If you’re wet and the suit is dry, that could lead to tears or damage to the suit because you’re trying to finagle your way in something that’s just not working.The chest should be tight but should obviously not cut off any blood flow or restrict you from breathing. If the shoulders, chest and underarm fit snug, there is less chance of water entering your suit.
