Wetsuit Temperature Guide: What Thickness Do You Need?

Why it matters

The right wetsuit keeps you warm longer, so you catch more waves and shiver less. Here’s the simplest way to choose.

Quick guide (by water temp)

  • 24–20 °C: 2/2 springsuit or shorty. Optional jacket for windy days.

  • 20–16 °C: 3/2 full suit. Thin boots if your feet run cold.

  • 16–12 °C: 4/3 full suit + boots. Consider gloves on longer sessions.

  • 12–8 °C: 5/4 (or 5/4/3) + boots + gloves; hood on windy days.

  • ≤8 °C: 6/5/4 with built-in hood + boots + gloves. Warm up before paddling.

Quick tip: If you’re skinny or hate the cold, size up one thickness.

Fit basics (fast checklist)

  • Snug, not strangling. No big gaps or flushing at neck, wrists, or ankles.

  • No baggy knees or lower back. That’s where cold water sneaks in.

  • Arm test: Raise your arms overhead—if it pinches hard, try a stretchier model or size up.

Zipper styles (keep it simple)

  • Back zip: Easiest to get on; a bit more flushing.

  • Chest zip: Warmer seal; a touch trickier to enter.

  • Zipless: Light, stretchy, warm; needs good technique to get in/out.

Care that doubles the lifespan

  • Rinse with fresh water after every surf.

  • Dry inside-out in shade (sun kills neoprene).

  • Hang on a wide hanger or fold at the waist to avoid shoulder stretch.

  • No hot water, no washing machine, no harsh soap.

FAQs

Do I need boots?
If water is ≤16 °C or your feet go numb, yes. Warm feet = longer sessions.

Chest-zip vs back-zip—what should I pick?
If you value warmth and performance, chest-zip. If you want easy entry, back-zip.

How tight is too tight?
You should breathe normally and paddle without shoulder burn in the first minute.
