In which season do the Great Lakes tend to warm winds passing over them?

The Great Lakes tend to warm winds passing over them during the winter season. This phenomenon occurs due to the relatively warmer waters of the lakes compared to the cold air temperatures that are common in winter. When cold winds blow over the lakes, they pick up heat and moisture from the water surface, leading to milder conditions in the surrounding areas.

As winter progresses, the heat retained by the lakes can influence weather patterns, often contributing to lake-effect snow and milder temperatures near the lakeside. This warming effect is a significant aspect of the Great Lakes' climate influence, contrasting sharply with the colder, drier air that typically dominates the winter months.

In spring, summer, and fall, while there may be some temperature influences from the lakes, the primary effect of warming air occurs in winter when the temperature differentials are most pronounced.
