Coastal regions in the U.S. tend to have milder climates compared to inland areas, thanks to the temperature-regulating effects of large bodies of water.

Because of the effect of the oceans and huge lakes, the climates of coastal locations in the United States are milder than those of inland areas. Water heats and cools more slowly than land because of its enormous heat capacity. Because of this, coastal regions have more temperate weather, with milder winters and colder summers than those further inland. By stabilizing temperature extremes, this impact contributes to the creation of a more temperate environment. When compared to locales farther from the coast, coastal regions with mild, temperate weather, such as cities like San Francisco and Seattle, are desirable places to live.
