Fast Weather Facts and Folklore

AMAZING WEATHER FACT - Land and Water: Land warms and cools faster than oceans or lakes (it takes five times more heat to warm one gram of water compared one gram of soil). So in the summer, daytime temperatures near the ocean are cooler than temperatures inland. At nighttime, because the ocean's temperature doesn't change very quickly, coastal temperatures are warmer.
