Best Answer: Because water heats and cools much slower than air, these large bodies of water have a moderating effect on land temperatures. In spring, when air temps over land are getting warmer, the body of water, which stays cooler much longer, cools the air immediately surrounding it. Likewise, in fall and winter, when cold air spreads over the land mass, these bodies of water retain their warmth, preventing temps from getting as cold around them. That is the effect that lakes have on land temperatures. The prevailing winds are also a large factor. Oceans provide land and sea breezes.
To compensate, the air will sink over the ocean. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean. At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This can be compared to a blacktop road. During the day, the blacktop road heats up and becomes very hot to walk on. At night, however, the blacktop has given up the added heat and is cool to the touch.
