Large bodies of water tend to moderate the temperature of nearby land due to the high heat capacity of water. This high heat capacity results from both the higher specific heat of water and the mixing of heat throughout a greater depth over oceans. Large bodies of water, such as oceans, seas and large lakes, can affect the climate of an area. Water heats and cools more slowly than landmasses. Therefore, the coastal regions will stay cooler in summer and warmer in winter, thus creating a more moderate climate with a narrower temperature range. The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles. So the concept that the hottest place on earth is around the equator and the coolest is on the poles is wrong. It is hotter in the desert than around the equator because the weather in the desert is very dry so when the temperature rises and it doesn't rain the temperature will rise even higher

Climates near large bodies of water are more stable than those inland because water has a higher specific heat capacity than land. This means that water can absorb and store more heat energy than land before its temperature rises, and it can also release heat energy more slowly than land when its temperature drops. As a result, areas near large bodies of water experience less extreme temperature fluctuations than areas inland, which can lead to more stable climates.

The waters at the equator are warmer than water at higher latitudes because of the distribution of solar radiation. Near the equator, the sun's rays strike the Earth's surface more directly, leading to higher levels of solar radiation and therefore more heat. This results in warmer water temperatures at the equator. At higher latitudes, the angle of the sun's rays is more oblique, leading to lower levels of solar radiation and cooler water temperatures.

In addition, ocean currents also play a role in determining water temperatures. Warm ocean currents, such as the Gulf Stream, transport warm water from the equator towards higher latitudes, contributing to the higher water temperatures in those regions. Conversely, cold ocean currents, such as the Labrador Current, transport cold water from higher latitudes towards the equator, leading to cooler water temperatures in those regions.

Dear Jurabek Muzaffar Ugli Abdiev thank you for your contribution to the discussion

In fact the ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles. At high latitudes, ocean waters receive less sunlight the poles receive only 40 percent of the heat that the equator does. 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. When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct. Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures. The ocean water temperature is directly affected by the amount of radiation received from the sun on the ocean's surface. Since the latitudes closer to the equator receive direct sunlight all year round, the ocean surface is relatively warmer in these regions. As solar radiation is more intense near the equator, water at lower latitudes wills to be warmer than water at higher latitudes. The water bodies like the Ocean of the region north and south of the tropic allow the release of heat in winter and during summer, it soaks up heat. It acts like a heat sink due to which there is a moderate range of temperature. Ocean currents led to the climate effect on the regions which are close to sea. Air that is in contact with the ocean will be much cooler from energy transfer between water and air, while air that sits above land will heat up much more quickly. Therefore, coastal climates are much more temperate because a body of water is nearby to regulate the temperature and keep it more constant. More water vapor exists in the air around locations near large bodies of water which absorb much of the moisture from the surrounding water. These locations will warm up during the day, but will remain cooler in comparison to other locations farther inland and will keep the temperature at a comfortable level.
