The Great Lakes are insanely hot right now
The Great Lakes are surprisingly warm for this time of year. Great Lakes temperature data goes back to 1995, and most lakes are the warmest they were on the last day of August.
Lakes Michigan, Huron, Erie and Ontario all show the warmest August 31 values since the database began in 1995.
Lake Superior is on its third hottest reading for August 31.
Lake Michigan has an average temperature over the entire lake of 73.886 F, according to NOAA’s CoastWatch. The second hottest reading for August 31 was 73.706 degrees F in 1998. Lake Michigan is currently 4.2 degrees F above long-term average temperature.
Lake Huron now sits at 72.392 degrees F, which is much warmer than the second hottest late August reading of 69.782 degrees F. Lake Huron is five degrees warmer than normal.
Lake Erie is 78.764 degrees today, topping 77.882 degrees F in 2016. Lake Erie is 5.1 degrees warmer than normal.
Lake Ontario is a deep lake, but it warmed to 75.938 degrees F, more than two degrees warmer than the second warmest on August 31. Lake Ontario is 5.2 degrees F warmer than normal.
Lake Superior seems cooler, but it is also very warm. Currently averaging 64.256 degrees F, and in third place behind 1998 and 2016.
The Great Lakes have never been warmer in late summer, at least since the good data began in 1995.
