Lake Audubon Water Temperature -- Thursday Morning July 2 was measured in the middle of the lake at 2 different locations --- 78.5 F and 25.7 C... So its near the limit of allowing wet-suits...here is the text from the WPFG Tri Rules -- Wet suits or open water suits
are not permitted when water temperature is above 77 degrees F. -- best to be prepared either way. A final measurement is performed Friday morning before the race.
