Water temperature and wetsuits at Twin Lakes Triathlon

Around August 7, North Twin Lake typically runs about 78°F at the surface (76 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.
