Detailed explanation-1: -What is the warmest body of water on Earth? The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6, 500 feet.

Detailed explanation-2: -Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface.

Detailed explanation-3: -The warmer ocean currents are near to the equator and the colder ocean currents come from the north and south poles.

Detailed explanation-4: -These variations in solar energy mean that the ocean surface can vary in temperature from a warm 30°C (86°F) in the tropics to a very cold-2°C (28°F) near the poles.
