Michigan's climate is heavily shaped by the Great Lakes, which surround the state on three sides and create pronounced lake-effect weather patterns. The Lower Peninsula has a humid continental climate, while the Upper Peninsula experiences subarctic conditions during winter. The moderating influence of the lakes delays seasonal transitions, keeping springs cooler and autumns warmer near the shorelines.
