2022 Annual Climate Trends and Impacts Summary for the Great Lakes Basin

Coordinated by a partnership between climate services organizations in the U.S. and Canada, this product provides a synthesis report summarizing the previous years’ climate trends, events, new research, assessments, and related activities in the Great Lakes Region. This product is a contribution to the U.S.-Canada Great Lakes Water Quality Agreement, through Annex 9 on Climate Change Impacts, and to the national climate assessment processes in the U.S. and Canada. It should be cited as: Environment and Climate Change Canada and the U.S. National Oceanic and Atmospheric Administration. 2022 Annual Climate Trends and Impacts Summary for the Great Lakes Basin. 2023.

During the 2022 reporting period, air temperatures were near normal and precipitation varied widely across the Great Lakes basin. Heavy springtime  precipitation in the northwest was contrasted with fall drought conditions in the southeast. Both contributed to rapid seasonal shifts in Lake Superior and Ontario water levels, respectively. Water levels remained predominantly above average, with the exceptions of the beginning of 2022 for Lake Superior and  the latter half of 2022 for Lake Ontario. At 56.1% areal coverage, Great Lakes maximum ice cover in 2022 was above the long-term average.
