All of the Great Lakes including Lake Superior are now ice free. This marks the end to a 7 month stretch where the lakes were covered in at least one ice cube, which is the longest streaks since satellite records began back in the 70’s. June 7th became the official ice out date of the lake which also makes in the latest in the year ice has coated the water. There was still a third of the Lakes coated in ice the last week of April which was the largest amount of ice that late in the year, a trend that continued into June.
Typically, the lakes get their first coating of ice around the first of December and have ice cover through the first week of May, but this year we topped our average ice cover streak by a solid 6 weeks. Here is what the current ice cover looks like…
Wait… there is still color on the map, even though it shows 0% ice cover. That is correct… there appears to be a chunk of ice that’s still remaining across the southeastern portion of the lake, but that doesn’t appear to be part of the “official” ice cover measurement. Here is a satellite image taken Sunday afternoon that shows the iceberg type piece flowing along the southern edges of the lake.
Because of the ice, lake temperatures are still astonishingly cold with the average Lake Superior water temp still in the 30’s.
