The National Oceanic Atmospheric Administration said this year marked a record low in ice coverage on the Great Lakes, which comes as no surprise to  Minnesotans who experienced the warmest winter in well over a century.

In a post to its blog, NOAA’s Great Lakes Environmental Research Laboratory said this year’s average ice coverage across all of the lakes came out to 4.3%, the lowest recorded average since records began in 1973.

Maximum ice coverage on the Great Lakes for this winter was recorded on Jan. 16 at 16%, the fourth lowest annual maximum recorded. The lowest annual maximum was recorded in 2002, at 11.9%.

NOAA also reported record low seasonal ice coverage in Lake Superior, Lake Huron and Lake Michigan, with Lake Huron also recording its lowest annual maximum ice coverage.

Average ice cover on Lake Superior for this winter was 2.6%. On Lake Michigan, it was 4.4%. Lake Huron recorded an average of 7.8% ice cover, as well as an annual maximum of 22.7% coverage.

In a previous interview with the Advance, Ayumi Fujisaki-Manome, an associate researcher at the Cooperative Institute for Great Lakes Research, explained that this year’s record-lows in ice coverage were the result of long-term warming trends alongside anomalous weather conditions.

El Niño conditions contributed to a warmer and wetter winter than normal. Due to a warm December, coupled with above average air and water temperatures throughout the winter, the conditions needed for ice did not develop, Fujisaki-Manome said.

Howie: Before Duluth asks taxpayers for more, answer the $4.55 million question

"Redirecting those dollars to the enormous backlog of aging and deferred capital needs was a deliberate financial decision, and one I continue to strongly support. As I said in my 2026 State of the City, Duluth has too much of everything, and much of it is too old." -- Duluth Mayor Roger Reinert
