Why it is cooler by the lake in the summer and warmer in the winter?

Lakes have a moderating effect on temperature due to their high specific heat capacity, which means they can absorb and store heat. In summer, water absorbs heat from the sun, keeping the air above the lake cooler than surrounding areas. Conversely, in winter, lakes release stored heat slowly, making the air above them warmer compared to the colder land areas. This phenomenon results in cooler summer temperatures and milder winter temperatures near lakes.
