Why are extreme temperatures unusual on land near any large body of water?

Extreme temperatures are unusual near large bodies of water because water has a high specific heat capacity, meaning it can absorb and retain heat more effectively than land. This moderating effect leads to milder temperatures, as water heats up and cools down more slowly than land does. Consequently, coastal areas typically experience less variation between summer and winter temperatures compared to inland regions. Additionally, the evaporation from the water surface can also contribute to increased humidity, further stabilizing temperature extremes.
