Why does Lake Michigan stay cold even though it's a hot summer day?


Why does Lake Michigan stay cold even though it's a hot summer day? There is a seasonal lag in temperatures when it comes to Lake Michigan. Water takes much longer to heat up and much longer to cool down than land. We can easily experience this phenomenon at the beach on a summer day. The sand gets hot fast and the water stays cool, then gradually warms as the season wears on.
