In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day

The cool breeze blowing from a lake onto a beach on a sunny day is a result of differences in thermal energy. During the day, the land heats up faster than the water, causing warm air to rise over the land and cooler air to move in from the lake to replace it. This movement of air creates the cool breeze felt on the beach.
When cool air moves from the oceans towards the beach during the day, it is known as a sea breeze. This happens because land heats up faster than water, causing the air above the land to rise. As the warm air rises, cooler air from the ocean moves in to replace it, creating the sea breeze effect.
It uses insulation which reduces the amount of heat entering the container by reducing the effects of conduction.
Typically, the air over the ocean would be cooler than over nearby land on a summer day due to the ocean's slower rate of heating compared to land. Water has a higher specific heat capacity than land, meaning it takes longer to heat up and longer to cool down. This temperature difference can create sea breezes, where cooler ocean air moves inland to replace the warmer air rising over the land.

hummm i dont really know i think it is food
Most of the time it is because the wind is bringing in cooler air from another country or part of the ocean
Usually a beach has a breeze blowing in from the ocean. This movement of air can cool your skin and make the temperature seem less. I would think that the air is still in the morning and as the sun heats up the air and land, this results in movement of the air.

A sea breeze would form when cool air moves from an ocean onto dry land. The air over the ocean is cooler than the air over the land during the day, causing the cool sea breeze to move inland. This flow is typically strongest during the day when the temperature difference between the land and sea is greatest.
On a warm day, water absorbs from its warmer environment, lowering the air tempurature. On a cool night, heat is transferred from the water to its cooler environment, raising the air tempurature.
How Does it Work?The heart of an evaporative cooling system is the pad where the water evaporates and the air passing through the pads is cooled. A special water distribution system spreads water over the surface of the pad, ensuring a uniform supply of water to keep the entire air contact surface thoroughly wetted. Fans create a negative pressure, causing air to be drawn through the pads. Evaporation results from contact between air and water. A control system operates the water pump and the fan distributes the cool air.The relative humidity is lowest in the afternoon when the temperature is at its highest. And the lower the humidity, the better the evaporative cooling effect. In other words, the cooling effect is best when you need it the most.Source: www.bajarangs.com/whyevaporativecoolers.html
Because there is usually a lower temperature at night then in the day time.Answer:Water, during the day, picks up heat from the sun quicker thna it loses it to evaporation. Thus it stays warmer. At night the water tends to lose heat by evaporation as it ties to reach the wet bulb temperature of the air. This is usually cooler han the air temperature we record on a thermometer (dry bulb) so the water can get cooler than the air. The evaporation also cools the water (the hor molecules are the ones that evaporate).
Cool breezes during the day are caused by the differences in heating and cooling rates between land and water. During the day, land heats up faster than water, causing the air above the land to rise and creating lower pressure. This draws in cooler air from the water, resulting in a cool breeze.
Typically, the late morning and afternoon have the most wind due to the heating of the Earth's surface, which causes air to rise and cooler air to move in and replace it. This creates wind as the cool air rushes to fill the void left by the rising warm air.
