Lake Superior surface-water temperatures averaged 1 or 2 degrees Fahrenheit below their long-term average at the end of May. According to the new forecast, surface temperatures over the deepest parts of the lakeâbetween 1,000 and 1,300 feetâwill be at least 6 degrees below normal by August and will still be in the 40s.
To conclude, summer temperatures in Lake Superior (and Huron and Michigan, by the way) are increasing due to two separate but related trends: summer air temperatures are increasing, and winter ice cover is decreasing.
