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.
What else can I help you with?
Why does the water in a swimming pool feel cooler than air during the day but warmer than the air at 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 !
What time of day do you put the pool cover on?
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
Why is the ocean warmer at night?
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.
Why is your pool water colder than the Gulf of Mexico when you live within a few feet of it in St Pete Fl?
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.
Can you run your pool filter at night to eliminate high costs approximately 3 hours a night?
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!
What happens to dew as the day gets warmer?
As the day gets warmer, dew evaporates into the air. The sun's heat causes water droplets to turn from a liquid state into water vapor, which then rises into the atmosphere.
Why deserts are very hot in day time but very cold in night?
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.
Why do I feel warmer at night compared to during the day?
You may feel warmer at night compared to during the day because your body temperature naturally rises in the evening as part of your circadian rhythm, and your surroundings may also retain more heat at night. Additionally, your metabolism tends to slow down during sleep, which can make you feel warmer.
When is the best time of the day or night to put alum into the swimming pool?
Night around 1130 pm
Why is it warmer in the day than the night?
During the day, the sun's rays heat the Earth's surface, causing temperatures to rise. At night, there is no sunlight and the Earth's surface loses heat through radiation, which leads to cooler temperatures.
How can thick clouds keep us cooler in day and warmer at night?
the thicker the clouds the cooler they are
Do you use a solar cover during the day to heat the pool or at night to keep the heat in the water or use it all the time if you are not swimming in the pool?
Leave the solar cover on - day and night. During the day, cover will absorb the heat from the sun and transfer that heat directly into the water. At night, the cover will help to retain the heat absorbed during the day and reduce evaporation. Hope this helps ... The original purpose of a solar cover is the ability to have the sun (err, solar) heat the pool thru the cover. If the cover is off during the day and on at nite you've wasted a $100+. C'mon, lets use a little common sense.
