PORT CALCULATOR
Wetsuit Thickness Calculator
Calculate the optimal wetsuit thickness based on water temperature for maximum comfort and safety.
What is the Wetsuit Thickness Calculator & How does it work?
A wetsuit is designed to keep you warm in cold water by trapping a thin layer of water between your skin and the suit. The thickness of the wetsuit depends on the water temperature. Generally, as the water temperature decreases, the wetsuit needs to be thicker to maintain body heat.
T_w = \frac{\Delta T}{k \cdot A}
T_w = Wetsuit thickness, \Delta T = Temperature difference between body and water, k = Thermal conductivity of the wetsuit material, A = Surface area in contact with water.
The formula above helps determine the thickness required to maintain a comfortable temperature. However, practical guidelines often suggest specific thicknesses for different temperature ranges:
- Water Temperature > 25°C: No wetsuit needed
- 18°C – 24°C: 3mm thick
- 10°C – 17°C: 5mm thick
- < 10°C: 7mm or more thick
