The ocean doesn't come in one temperature, and neither should your gear. Here's everything you need to feel confident, comfortable, and ready to paddle out, no matter where your board takes you.
Walk into any surf shop and the wetsuit wall can feel overwhelming. Millimeter numbers, back zips, chest zips, full suits, spring suits; it's a lot. But once you understand the logic behind the choices, picking the right suit becomes surprisingly intuitive. Think of it less like shopping and more like dressing for the weather. Because that's exactly what it is.
Start with your water temperature
Everything begins here. Water temperature, not air temperature, is the deciding factor in what you wear. A sunny 75°F beach day can sit above 58°F water that will leave you shivering in 20 minutes without the right suit. Always check the actual ocean temperature for your surf spot before you gear up.

Decoding thickness: what those numbers mean
Wetsuit thickness is measured in millimeters and usually written as two numbers — like 3/2 or 4/3. The first number is the thickness in the torso (your core, which needs the most warmth), and the second is the limbs. A 3/2mm suit has 3mm of neoprene at the chest and back, and 2mm at the arms and legs for better flexibility where you need it most.

A note on body temperature: Everyone runs differently. If you tend to get cold quickly, size up in warmth — don't tough it out. Being cold in the water isn't just uncomfortable, it shortens your sessions and affects your judgment in the lineup. Surf longer, stay warmer.
Full suit, springsuit, or just a bikini?
Once you know your temperature range, you can choose your wetsuit style. Each has a distinct purpose — and knowing when to reach for each one makes all the difference.
-
Full Wetsuit Full-length arms and legs with a sealed neck. Your go-to for cold to mild water. Maximum coverage means maximum warmth. Best for: below 68°F.
-
Spring Suit / Shorty Short arms and short legs (or long body with short sleeves). Great for warmer water when you want some protection but not the full suit. Best for: 65–72°F.
-
Long-John / Jane Sleeveless with full-length legs. Often layered under a jacket. Great for paddlers and SUP who generate more upper-body heat. Best for: 60–68°F.
-
Rash Guard + Bikini No neoprene needed. A rash guard adds UV protection and board rash protection. Pair with a well-fitted surf bikini for warm tropical sessions. Best for: 72°F and above.
Know your break: location matters
Where you surf shapes everything about your wetsuit choice — not just temperature, but ocean conditions, session length, and even sun exposure.

Zip style, seams, and construction
Wetsuits come in different zipper configurations and seam constructions that affect warmth, ease of entry, and durability. These details matter more than most beginners expect.
-
Back zip — Easy to get into, great for beginners. The zipper can let in small amounts of water, but modern designs minimize this significantly.
-
Chest zip — Warmer and more flexible. The entry panel sits across your chest. It takes some practice to get on, but surfers in cold water swear by it.
-
Zipperless — Maximum flexibility and zero flushing. Instead of a zipper, you enter through a flexible shoulder opening that stretches to make getting the suit on and off easier. A snug fit helps limit water entry.
-
Seams — Flatlock seams are fine for 65°F+. Glued & blind-stitched (GBS) seams are warmer and waterproof — essential below 65°F.
Fit: the most important detail
A wetsuit that doesn't fit right won't keep you warm — no matter how thick it is. Wetsuits work by trapping a thin layer of water against your skin, which your body heats up. Too loose, and cold water flushes through constantly. Too tight, and you'll be restricted, uncomfortable, and maybe unable to paddle for long.
-
The suit should feel snug like a second skin — not tight enough to restrict breathing or arm movement
-
There should be no excess neoprene bunching behind the knees, at the crotch, or in the armpits
-
The neck should seal without choking — you should be able to fit two fingers underneath
-
Raise your arms overhead and do a paddle motion in the store — you shouldn't feel like you're fighting the suit
-
Wetsuits stretch slightly over time as the neoprene breaks in, so a slightly snug fit on a new suit is expected
Fit note for women: Most wetsuits are designed from male patterns — historically that's just been the industry default. At Spring Tides, we specifically source and vet suits with women's cuts: proportioned for hips, chest, and shorter torsos. Never settle for a suit that fits "well enough." A properly fitted women's suit will transform your experience in the water.
Sustainability: what to look for
Traditional wetsuits are made from petroleum-based neoprene, which has a significant environmental footprint. The good news? The surf industry has been changing. Here's what to look for when shopping sustainably:
-
Limestone-based neoprene (like Yamamoto) has a lower carbon footprint than petroleum neoprene and tends to be more flexible and durable
-
Natural rubber or plant-based neoprene alternatives are emerging from brands committed to reducing chemical processing
-
Recycled liners made from repurposed plastic bottles — look for certifications like bluesign® or Fair Trade on the product label
-
Longevity is sustainability: a quality suit that lasts 5–7 years beats a cheap one you replace every season
-
Wetsuit repair instead of replace — small tears and worn seams can often be fixed with neoprene cement rather than sending a suit to landfill
Accessories: when do you need them?
In water below 55°F, accessories stop being optional. Exposed extremities lose heat fast, and cold hands make paddling and pop-ups much harder.

Quick-reference buying checklist
Before you commit to any wetsuit, run through these questions:
-
What is the average water temperature at my main surf spot — in both summer and winter?
-
Am I buying a one-wetsuit quiver, or can I invest in two suits for seasonal rotation?
-
Does the suit have a women's cut, or is it a modified men's pattern?
-
What seam construction is used — flatlock (warm water only) or GBS/sealed (cold water)?
-
Is the neoprene limestone-based, recycled, or natural rubber?
-
Does it fit snugly without restricting a full paddle motion?
-
What is the brand's repair and warranty policy?
The water is for everyone. Your gear should be too.
