Water Temperature Recommendations By USA Triathlon
Courtesy of WOWSA, Huntington Beach, California. Back in 2014, race directors of triathlons sanctioned by USA Triathlon were required to submit a detailed swim course report after each sanctioned race via the event reporting tool through the USA Triathlon sanction database.  Triathlon race directors submitted their reports online with the rest of post-race deliverables, due 15 business days after the event. The required information included:
  • Air temperature at start of race (use local weather resource or weather.com)
  • Humidity at start of race (use local weather resource or weather.com)
  • Water temperature day prior to race
  • Water temperature day of race prior to swim
  • Number of athletes that started the swim (add relay participants)
  • Number of athletes that voluntarily withdrew during the swim (include relay participants)
  • Number of athletes rescued during the swim (include relay participants)
  • Number of athletes that completed swim (include relay participants)
  • Swim DNF’s (include relay participants)
  • Number of athletes requiring medical attention (any transport from swim other than “I’m too tired“)
  • Number of athletes requiring medical transport (obtain information from incident reports)
The USA Triathlon has implemented a new set of recommendations for sanctioning race directors.  Its Water Temperature Recommendations are listed above. This chart includes elements like wind and humidity when considering the cancellation of any swim.  Race directors were encouraged to share the recommendations with their swim course team, supporting entities, and athletes.
