Wetsuit thickness depends on water temperature. Above 72°F, a rashguard or 1mm top suffices. At 60–72°F, use 2–3/2mm. Below 60°F, you need 4/3mm or thicker with accessories.
| Water Temp | Thickness | Accessories |
|---|---|---|
| 70–80°F | 1–2mm | None needed |
| 60–70°F | 3/2mm | Optional boots |
| 50–60°F | 4/3–5/4mm | Boots, optional hood |
| Below 50°F | 5/4–6/5mm | Hood, gloves, boots |
The numbers 4/3mm mean the torso is 4mm thick and the arms/legs are 3mm thick. The thicker torso keeps your core warm, while thinner limbs allow better flexibility for paddling and swimming.
Yes. Surfing and swimming generate body heat, so you can wear thinner suits. Scuba diving involves less movement and deeper (colder) water, requiring thicker neoprene. Kayaking stays above water, so a thinner suit often works.
In a properly fitted wetsuit, you can stay 1–4 hours depending on water temperature. At 60°F in a 3/2mm suit, expect 2–3 hours of comfort. Below 50°F in a 5/4mm with hood, limit sessions to 1–2 hours.
