Why do coastal areas remain cool in summer & net inflow of air molecules into a region of upper atmosphere with the result of increasing surface pressure?
The specific heat capacity of water is very high. It is about five times that of sand. Hence, temperature change is much less in water than that of land. Divergence occurs when horizontal winds cause a net outflow of air from a region while convergence occurs when horizontal winds cause a net inflow of air into a region. Places situated near the coasts are neither too hot nor too cold. They have a moderate climate. It is called Equable Climate. This is because of the land and sea breezes. 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. Coastal areas experience less contrasts in temperature conditions due to moderating effect of the seas. The large water bodies helps in moderating temperature. Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and to cool than the land.

Coastal areas will generally have more moderate temperatures than inland areas because of the heat capacity of the ocean. The specific heat capacity of water is very high. It is about five times that of sand. Hence, temperature change is much less in water than that of land. Air that is in contact with the ocean will be much cooler from energy transfer between water and air, while air that sits above land will heat up much more quickly. Therefore, coastal climates are much more temperate because a body of water is nearby to regulate the temperature and keep it more constant. 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. The coastal areas do not experience much variation in temperature between summer and winter months because they are influenced by the moderating effect of the sea. This is because of the moderating influence of the adjoining water bodies. The land and sea breezes moderate the temperatures.In coastal areas the amount of humidity in air is quite high; as rate of evaporation is lesser in humidity therefore they are not used in coastal areas. 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.
Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and to cool than the land. Coastal areas will generally have more moderate temperatures than inland areas because of the heat capacity of the ocean. In summer, a prevailing wind from the sea pushes cooler air into coastal areas and keeps them cooler than inland areas. The ocean also creates a humid climate in coastal areas. Humidity can trap heat in the air, so in winter, the air in coastal areas will be warmer than inland areas due to the higher humidity. This is because of the land and sea breezes.

Coastal areas experience less variation in temperature this is because of the moderating effects of water bodies. Water takes much time to heat up and cool down. Thus on hot days, water absorbs heat, keeping the air somewhat cooler. That is why coastal areas are cooler in summer and warmer in winter. Coastal areas enjoy equable climate because of the occurrence of sea breeze and also due the high specific heat capacity of water, it absorbs the heat over their land without itself becoming so hot, and thus, keeping the land cool and moderate.
