Humid continental climate. Winters are cold and snowy (−8 to 0°C) from December through March. Lake Erie and Lake St. Clair generate significant lake-effect snow that can fall heavily with little warning. Ice storms and blizzards cause the most serious flight disruptions.

Summers are warm and humid (26–32°C) with frequent afternoon thunderstorms. Spring and fall are transitional with frost risk into April and from October. January and February are the highest disruption-risk months.
