Ice on the Great Lakes.

January 17, 2014

DGL People are starting to wonder if the Great Lakes will freeze all the way across this winter since it is so cold.  In 1979 the Great Lakes froze nearly 95 per cent.  As you can see by the NOAA facts below, the Great Lakes are dynamic.  They change from year to year and from day to day and even morning until night.


These figures are for all five of the Great Lakes from NOAA.

Great Lakes Ice Cover facts since 1973

94.7% ice coverage in 1979 is the maximum on


9.5% ice coverage in 2002 is the lowest on record

– 11.5% ice coverage in 1998, a strong El Nino year

 38.4% ice coverage in 2012-2013

Read more about Great Lakes ice in my book, The Dynamic Great Lakes.  It is available at Barnes & Noble and and is available on Amazon’s Kindle reader.
