Document Description

Quarterly Climate Impacts and Outlook for the Great Lakes Region for September–November 2025. Dated December 2025.

Fall air temperatures averaged out to be near or above normal. Fall was drier than normal for most areas. Dry conditions led to greater than average declines on all lakes from the start of September to the end of November. In the period of record (1900-present), Lake Michigan-Huron experienced its 8th largest decline and Lake Erie had its 13th largest decline in water levels for fall.

NOAA’s Regional Climate Services Program created these climate outlooks to inform the public about recent climate impacts within their respective regions. Each regional report contains easy-to-understand language, and anyone can access them through the U.S. Drought Portal.
