I'm an expert in meteorology with a keen interest in the dynamics of weather patterns and their effects on local climates. Let's delve into the fascinating phenomenon of why it tends to be cooler near the ocean during the day.
The primary reason for the cooler temperatures near the ocean during the day is the differential heating rates between the land and the sea. The land heats up more quickly than the ocean due to its lower specific heat capacity. This means that for a given amount of heat, the temperature of the land will increase more rapidly than that of the ocean. As the land heats up, the air above it also warms and becomes less dense, causing it to rise. This process is known as convection.
Once the warm air rises, it creates an area of low pressure at the surface. The cooler, denser air over the ocean then moves in to replace the rising warm air. This movement of air from the ocean towards the land is what we refer to as a sea breeze. The sea breeze brings with it the cooler air from over the water, which helps to moderate the temperatures along the coast.
Another factor contributing to the cooler coastal temperatures is the high heat capacity of water. Water can absorb or release a large amount of heat with only a small change in temperature. This means that even when the sun is shining brightly, the ocean's surface temperature changes relatively slowly compared to the land. The slow temperature change of the ocean acts as a buffer, keeping the coastal areas cooler.
Additionally, the presence of water bodies can lead to increased evaporation. When water evaporates, it absorbs heat from the surroundings, a process known as evaporative cooling. This further contributes to the lower temperatures near the ocean.
Moreover, the ocean's surface is often covered by a thin layer of cool air due to the evaporation of water. This cool layer acts as an insulating blanket, preventing the rapid warming of the ocean surface and thus maintaining cooler conditions near the coast.
In summary, the cooler temperatures near the ocean during the day can be attributed to the differential heating rates between land and sea, the high heat capacity of water, the presence of sea breezes, evaporative cooling, and the insulating effect of the cool air layer over the ocean.

During the day, temperatures in the inland areas are warmer than the temperatures along the coast. The warm air rises and the cooler coastal air moves in to replace it. Since the air is moving from the sea toward the land, this type of breeze is called a sea breeze.
