Water temperature and wetsuits at Lake Lou Yaeger Triathlon
Around May 23, Lake Lou Yaeger typically runs about 73°F at the surface (68 to 81°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.
