Water temperature and wetsuits at Orange County Multisport Festival
Around April 25, the 123-acre lake nearest the race typically runs about 68°F at the surface (66 to 71°F across 2011 to 2020). Wetsuits were legal every year at this date.
A model estimate from the USGS lake temperature model (daily surface temperatures for US lakes), not a measurement; matched to the largest lake near the race's listed location, about 2.4 km away. Wetsuit cutoffs are USA Triathlon age-group rules. The race's own water temperature reading on race morning decides.
