A model computes; it does not observe. Accuracy drops with range, and nearshore transformation is where it is weakest.

What to wear

At 60.3 °F (15.7 °C), most people at Nantasket Beach are comfortable in a 4/3 mm full suit.

4/3 mm

for 58–62 °F

  • Boots help on longer sessions

Below 60 °F most people want their feet covered before their hands.

The temperature is measured. The suit recommendation is not — it follows the manufacturers' convention, which varies by a degree or two between brands, and it knows nothing about wind, session length or how you personally run. The full chart and what it leaves out.
