what temperature does the ocean have to be to allow wetsuits
78-84 degrees: Race directors use their judgement to allow or not allow wetsuits at this range. Over 84 degrees: Wetsuits not allowed. The range of 50 to 78 degrees is therefore the ideal range for using a wetsuit. Any warmer, and the swimmer may actually overheat due to the wetsuitâs insulative qualities. Any colder, and the water is dangerously frigid for a swim.
