Great Lakes Ice Cover Continues Climbing

Posted: Updated:

With the frigid cold continuing around the Great Lakes region, ice is still growing across some of the largest fresh water bodies in the world. This comes just 18 months after lake temperatures hit record highs ranging from 65 to 85 degrees. The ice extends to nearly 92% of the water surface and is several feet thick in some spots, which is quite uncommon. This is just shy of the all-time record ice content of 94.7% set back in 1979.

What's really cool to see is just how much the ice can fluctuate from day to day and week to week. With the graph below, it's pretty easy to see when the cold snap really got started for Lake Superior. It took just a month for the lake to go from about 5% ice cover near New Year's Eve to more than 75% ice cover by February 1st. Considering that Lake Superior is about the size of Indiana, that's impressive!
