the water collects the heat in the daytime and releases heat at night... so it feels like in the day its cold (cuz it is collecting and not releasing) and in the night it is warm (the warmth is being released)
Also besides the other answers, there is the difference between the water temperature and air temperature, which makes the water feel cool on a warm day, and warmer at night than the cool night air with no sun.
No, it does not.. the contrast of the cold rain and the warm water makes it feel like the water is warm. But it is not.
It is warmer during the day because the sun heats the air.
the day is warmer than it is at night is because, during the day the sun gives out heat waves (this is called radiation) to the earth. But at night the sun radiation is shining at the oppsite of the earth.
Water retains heat longer than the air does. As a result, at night when the temperature drops the pool is fairly close to the temperature it was during the day while the air around it can become significantly colder. The same effect occurs with the ocean where the warmest ocean temperature on the eastern US are in September when the relative air around it is much colder. Pools seem warmer at night because the air outside (ambient air) is normally cooler. The temperature of the pool at the end of the day is when its the warmest and it cools down overnight. So ususually by morning the water is not as warm as it was when you get in earlier during the night.
During the day - the side of the Earth facing the Sun heats up - the portion facing away from the sun is in night time - and thus is not being heated... making it cooler !
at night before u go 2 bed Or The pool cover , I think, would be on when the pool is not in use. Also, the cover should be off for a period of the day after you add chemicals to the water. The water needs to "gas off" after the addition of chemicals. k
Your pool has a much smaller amount of water in it than the Gulf. This means it changes temperatures faster. So in the day and during the summer it heats up faster than the gulf but during the winter and at night it cools faster. It makes sense that your pool is colder right now because the Gulf is still retaining heat from the summer that your pool has already lost. Another factor is that water in the ocean circulates and some of the water in Gulf is further south in where the water is warmer.
You can run the filter anytime of day you wish, however the pool has its biggest demand during the daylight hours so it is preferable to run the pool during the day and turn it off at night when there is less demand. If the water gets hot enough 90 degrees or above you should run it 24 hours a day until it cools down!
Earth or ground heats up and cools off more rapidly than water. Large bodies of water act as a heat sink. Areas near a coast are cooled during the day by breezes from the water and are kept warmer at night from the heat coming off the water at night. Desert temperatures have a greater variation between night and day because there is no ocean or sea nearby to moderate the temperatures.
the sand is warmer than water in day because the sands are compacted together, it easily gets the heat of the sun through out of it
This is not seriously a question :P Same reason it's warmer in the light than in the shade: The sun is out.
the thicker the clouds the cooler they are
Night around 1130 pm
