All the ice has made for another unpredictable shipping season in the lower Great Lakes with some ships requiring icebreaker assistance to make it. Open water except 1-3 tenths of new and thin lake ice near Duluth near the end of the month.

Great lakes ice coverage january 2019. Ice coverage remained near 2 very close the climatological ice amount. Warmer than normal temperatures set up over the lake in late December and early January with little change in ice cover when usually by the end of the first week of January ice cover should be up above 10.

National Oceanic and Atmospheric Administration ice coverage reports for January 9 in 2020 2019 and 2018. In fact since 1973 the Great Lakes have only been under 5 on. Ice coverage is currently at almost 38 per cent below the average of 53 per cent.

A rapid increase of ice coverage was observed on the Great Lakes following well below normal coverage during the first half of January and extremely cold Arctic Air that brought widespread record-breaking temperatures at the end of the month. This graph shows annual maximum ice coverage on the Great Lakes every year from 1973 to 2020.
The red dashed line marks the long-term average maximum ice cover of 533. GLERL scientists can also use this historic ice cover data to analyze how current ice cover conditions compare with previous years. For example heres how the ice cover during January 2021 stacks up.
Lake Michigans ice coverage is currently at 279 and Lake Hurons coverage is 379 at this time. The past week has seen significant ice growth nowhere more apparent than on Lake Erie the shallowest of all of the Great Lakes where the ice coverage is currently at 739. Finally Lake Ontario ice coverage is 116.
Ice cover on the Great Lakes can fluctuate dramatically from year to year controlled by four patterns of climate variability. The North Atlantic Oscillation the Atlantic Multidecadal Oscillation the Pacific Decadal Oscillation and the El Niño-Southern Oscillation. The highest maximum ice cover 947 percent on record occurred in 1979 and the lowest maximum 119 percent occurred in 2002.
Low ice cover also prevailed during the 2019-2020 season. The long-term trend in ice. The ice cover on the Great Lakes begins each year along shallower coasts during late fall and early winter and typically peaks in late winter and early spring.
