A model computes; it does not observe. Accuracy drops with range, and nearshore transformation is where it is weakest.
What to wear
At 69.6 °F (20.9 °C), most people at Nantasket Beach are comfortable in a 2 mm shorty or spring suit.
2 mm
for 68–72 °F
Short arms and legs. Enough for a couple of hours; wind changes that quickly.
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.

Surf and beach conditions change faster than this page does, and nobody watches it in real time. When the water looks different from the numbers, trust the water and the lifeguards.
