FORT WAYNE, Ind. (WFFT) — The hot start to the summer has warmed up the Great Lakes water temperatures.

The Great Lakes Environmental Research Laboratory is reporting well above average water temperatures.

Temperatures are ranging about 6 to 10 degrees Fahrenheit warmer than normal according to NASA.

Water temperatures at the southern end of Lake Michigan are in the mid-70s.

Temperatures remain in the 70s even as you approach the middle of the lake.

You can see current water temperatures here.

Lake Erie is the shallowest of the Great Lakes.

Water temperatures are in the mid to upper 70s.

It's as warm as bath water.

The warm water on Lake Erie can create algae problems.

When agriculture runoff, like fertilizers, flow into the lake it creates algae blooms on the western half of the lake.

Since the Midwest hasn't seen as much rain as usual for the past month and a half, it has led to less water draining into the lake.

This results in moderate algae bloom according to the Cleveland National Weather Service Office.

Lake Superior has the coolest temperatures which are in the low 50s.

The National Oceanic and Atmospheric Administration (NOAA) data shows the Great Lakes typically reach their maximum temperature in August.

But what does this mean for our upcoming winter?

Warmer water temperatures could help create more lake-effect snow.

If there isn't any cold air, then lake-effect snow cannot happen.

Polar air can descend on the Midwest and cool the Great Lakes quickly.

That happened when a piece of polar air moved over the region at the end January 2019.
