Water Temperature Guidelines: FINA’s Open Water Swim rules tell us that the lower limit for water temperature (measured 1 m below the surface) is 16 degrees C (60.8 F). If the water temperature is lower, the event may be shortened or canceled. This figure of 16 degrees C is based on the fact that both male and female swimmers will not experience dangerous declines in body temperature in water temperatures of 16 degrees C or higher when swimming at typical open water race speeds.

The minimum water temperature at which wetsuits are optional is 14 degrees C (57.2 degrees F)
At temperatures less than 12 degrees C (53.6 degrees F) the swim will be canceled.

Top 3 M/F Wetsuit in each swim distance - 1/2, 1.2 and 2.4 mile
Top 3 M/F Non-Wetsuit in each swim distance - 1/2, 1.2 and 2.4 mile
