Lake Audubon's temperature fluctuates during the day and is dependent on sunshine and rainfall. The 2-Mile race held at 9:45AM on 5/29/2016 is the only race in recent history where the water was above 78º and wetsuits were illegal. Wetsuits were legal for the 2016 1-Mile race at 8:00AM. We typically will publish water temperatures starting 2 weeks before the race, temperatures are taken at around 9:00AM and will be posted here.
