Water temperature and wetsuits at TRI Clear Lake 2027
Around August 28, Clear Lake typically runs about 75°F at the surface (71 to 80°F across 2011 to 2020). Wetsuits are usually legal, but in warmer years the water topped 78°F, when wearing one makes you ineligible for age-group awards.
A model estimate from the USGS lake temperature model (daily surface temperatures for US lakes), not a measurement. Wetsuit cutoffs are USA Triathlon age-group rules. The race's own water temperature reading on race morning decides.
