Which ocean is colder, the Pacific or Atlantic?

Although temperatures vary across both oceans, the Atlantic ocean is warmer on average, sometimes by as much as 16 degrees Fahrenheit at a given latitude. This is due to a number of factors, such as it being shallower, smaller and narrower than the Pacific ocean.

The Pacific ocean covers 35 percent of the Earth's surface, and the Atlantic covers only 21 percent. The Pacific ocean is the largest ocean and is almost as large as half of the other oceans combined. It also has the deepest average depth and the point of the lowest elevation on Earth.

The Atlantic ocean receives more fresh water through run-offs than any other ocean. The Amazon, Mississippi, Saint Lawrence and Congo all empty into it.
