Winter weather on Lake Michigan shoreline

NPS - Katrina George

The national lakeshore's weather is greatly affected by Lake Michigan and can change quickly. Summers are warm and humid with high temperatures generally in the mid-80sºF (30C) and low temperatures in the mid-60sºF (18C). There are about 15 days per year above 90ºF (32C). Warm periods are occasionally interrupted by frontal action descending from Canada. This generally brings days of pleasant, dry weather. Sunshine is abundant in summer. Highs in winter are usually in the low to mid 30sºF (0C) with low temperatures in the low 20sºF (-5C). There are about 15 days per year below 0ºF (-18C). Winters tend to be cloudy except for periods of extreme cold when skies are clear.
