Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range. Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range because the ocean releases heat more slowly than land, coastal areas tend to be more temperate. Upwelling in many coastal regions provides a cool contrast in air temperature over the ocean and land that is conducive to frequent summer fog. Since the sea doesn't get too hot or cold, the air above the sea also doesn't get too hot or cold. Therefore places near the sea usually have temperatures that remain fairly constant throughout the year.

Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range. A maritime climate is influenced by a nearby ocean. A continental climate is influenced by nearby land. The temperature of offshore currents affect nearby land areas. A maritime climate is less extreme than a continental climate, because the ocean moderates temperatures. During summers, high pressure develops over the coastal lands, so the cold winds move from the sea to the land, reducing the temperature of the region. The reverse happens in winters when high pressure develops over the sea. The sea has a moderating influence on the region close to it. Compared to land, water takes longer to heat and cool. Thus, oceans heat up and cool down slower than the land around them. Cool sea breeze keeps the coastal areas cooler in summer and warmer in winter than places far away from the sea. In coastal regions the amount of the water is more and the specific heat of water is much higher than of the land. Hence a major part of heat coming from the sun is absorbed by water the increase of temperature of water is less because of its higg specific heat. Hence the temperature of the land does not change much. As such, sand gets heated or cooled more rapidly as compared to water under the similar conditions. Thus a large difference in temperature is developed between the land and the sea due to which land and sea breezes are formed. These breezes make the climate near the sea shore moderate.
