Choosing a wetsuit for surfing (or bodyboarding) can feel a little overwhelming when you're starting out. What does 3/2 or 5/4 actually mean? What size should you go for? Chest zip or back zip? And do you really need to spend loads to get a decent suit?

With so many options out there, it can quickly become a bit confusing.

So, I've put together this guide to hopefully make the whole process a little easier and give you a better idea of what to look out for when choosing a wetsuit that'll keep you warm, comfortable and enjoying your time in the water.

1. Understand What The Numbers Mean

You'll often see wetsuits labelled something like 3/2mm, 4/3mm, or 5/4mm.

The numbers refer to the thickness of the neoprene in millimetres.

• 3/2mm = Great for warmer UK summer sessions

• 4/3mm = A solid all-round UK option and a favourite for spring and autumn

• 5/4mm = Built for colder water and winter surfing

As a rough guide:

☀️ Summer → 3/2mm🍂 Spring / Autumn → 4/3mm❄️ Winter → 5/4mm+

2. Get The Right Fit

A wetsuit should feel snug — but not uncomfortable.

Too loose and cold water can flush through the suit.
Too tight and paddling can become hard work.

Different brands can fit differently too, so always check sizing guides.

3. Chest Zip Or Back Zip?

Back Zip

Easier to get on and off• Great for beginners• Usually a bit cheaper

Chest Zip

Often warmer• Less water getting in• Popular with regular surfers

Neither is right or wrong — it depends what works for you.

4. Think About How Often You'll Surf

Heading out regularly? Spending a little more can sometimes be worth it. Trying surfing for the first time? You probably don't need the most premium suit on the market. Choose something that'll suit how often you'll realistically get in the water.

5. Don't Overthink It

The perfect wetsuit doesn't exist. Find something that fits well, works for UK conditions and gets you excited to get in the water. The rest can come later.

Hope this has helped you in choosing your first wetsuit!
