In what way does coastal proximity influence summer temperatures?

Coastal proximity significantly influences summer temperatures primarily due to the moderating effects of large bodies of water. Water has a high specific heat capacity, meaning it can absorb and store a considerable amount of heat without a significant rise in temperature. As a result, coastal areas tend to experience milder summer temperatures compared to inland regions.

During summer, land heats up much faster than water does because of its lower heat capacity. Consequently, coastal areas benefit from breezes that bring cooler air from the ocean, helping to regulate and lower summer temperatures. This phenomenon creates a more temperate climate along coastlines, thus resulting in cooler average temperatures in summer compared to areas further inland.

Additionally, the presence of water also contributes to higher humidity levels, but the primary factor influencing temperature is the cooling effect of the ocean. The combination of these factors underscores the importance of water bodies in shaping the climate and temperature profiles of coastal regions.
