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.
Some scientists believe that prior temperature anomalies have already begun to alter and slow the Gulf Stream and the balance of the currents circulating through the Atlantic over the past 100 years or so. The temperature of surface ocean water can vastly affect the temperature of nearby land areas. In a short-term example, people along the New England coast notice the routine chilling effect the cold Labrador Current and a sea breeze have on their weather during a number of days in the spring.
