It’s not quite bathwater warm — that honor goes to Lake Erie — but Lake Michigan’s average surface temperature is a downright comfortable 72.5 degrees at the moment, according to the National Oceanic and Atmospheric Administration’s Great Lakes Environmental Research Laboratory.

The current reading is quite a jump from the same time last year, when the surface temperature average was 63.8 degrees, and 64 degrees recorded in 2018. Indeed all of the Great Lakes are above normal, temperature-wise, according to the National Weather Service.

Though a recent string of hot days has sent Lake Michigan’s surface temperature soaring, the effects don’t penetrate the water’s depths.   

A dive into the data shows that at bottom, Lake Michigan is a chilly 44.7 degrees, holding fairly steady compared with 44.1 degrees in 2019 and 44.9 degrees in 2018.
