San Diego weather is often the weather that laughs at you. For some reason, the forecast will say clear skies and clouds will roll in off the ocean, or the forecast will tell you to wear a jacket for an overcast day and the sun will come out to play.
A sea is a large body of saline water that may or may not be connected to an ocean, though commonly these are. However, the body is smaller compared to an ocean. It is believed to lack a natural outlet. Seas are usually located near land and are used to connect the land with an ocean.
An ocean (from Greek , okeanos Oceanus) is a major body of saline water. The ocean covers 71 percent of the Earth's surface and contains 97 percent of the planet's water, yet more than 95 percent of the underwater world remains unexplored. The ocean and lakes play an integral role in many of the Earth's systems including climate and weather.
