The Surface Water &Global Temperature

Thermal Inertia: San Francisco and Norfolk, Virginia are on the same latitude meaning they are the same distance from the equator. However San Francisco is warmer in the winter and cooler in the summer than Norfolk, Virginia is because of the air. The air in San Francisco has moved over the ocean, while Norfolk is over land.

Temperatures moderated on water take much longer than air to heat up and longer to cool. Therefore, on hot days, water (oceans,lakes, rivers) absorbs heat keeping the air somewhat cooler. When air gets cool, water slowly releases heat to the atmosphere raising the air temperature.
