Layers of Warmth

Our lake’s temperature may surprise you!
Just like to ocean, the lake takes a long time to warm up and long time to cool down.  The water is the warmest July through September. The surface water temperature usually does not vary more than four degrees from this graph.

The surface temperature in the summer is in the mid to upper 70’s (°F); however, there are thermoclines throughout the lake. There is about a 10º temperature drop every 30 feet. The bottom stays in the mid to upper 40’s year round.  In order to comfortably explore all of our underwater attractions, we recommend divers wear at least a 7mm wetsuit with a hood and gloves year round.
