I mean like this is basic Earth Science, so my explanation will be short. Umm... so let me get to the point. A swimming pool is filled with water, right? And cement around it is considered land, right? So, the specific heat of land is much lower than the specific heat of water. This means that it takes much more energy, temperature and time, to increase the temperature of water. Whereas, lands specific heat is lower, so it will heat up faster, and as a result in most cases the temperature of land is higher than water. Hope this helped!!

∙ 14y agoI think the main reason is to do with something called specific heat capacity. This is a measure of how much energy it takes to make something get hotter. Concrete has a specific heat capacity of 0.88 Joules (that's energy, as from the sun) per gram per degree hotter. Water needs much more energy to get it the same amount hotter, 4.2 J/g/K. The reasons why are to do with the way the atoms are bonded and arranged together inside the substance. So the pool was filled with water at the start of summer and spends all summer getting hotter, but slowly, while the concrete got hotter quickly. If you left the water there long enough it would stop feeling cold - or if you had a smaller pool it would warm up faster. I think a second reason is that when you wet your hand in the pool, the water then evaporates off your hand and that cools your hand, giving the impression that the water is colder. There is likely more to this question and I invite further answers.

Sorry I don't have much information. I am wondering this myself too.
I think I'll take a peek into my science textbook......

It feels hot because the heat waves aims at the concrete and it takes longer for water to hear up

Why is it when it's raining the water in the swimming pool is warm but when it is sunny the water in the swimming pool is cold?
It's all about how your body reacts to relative temperatures. The truth is that the pool temperature is not likely to be the culprit. It's more about how your body perceives the difference between the outside temperature vs the pool temperature. The transition from standing in the hot sun to getting into your pool makes the water feel colder than it might feel than if you are standing in cold rain before entering the pool.
Do black bottom pools keep water warmer then a normal pool?
Yes. We had a black/brown pepple tec installed over our stained concrete pool and it does make the water a little warmer. Not significantly but noticeble enough to enjoy a quick dip.
Why does a pool not evaperate?
A swimming pool? It will if it sits long enough. It takes a long time for that much water to evaporate. It also depends on weather conditions like heat, humidity and direct sunlight. A pool does not evaperate because the water is not cold enough.
How do you keep pool water cold?
It can be done with a commercial refrigeration unit, but these are very expensive. The easiest way is to fill some balloons with water and freeze them in a domestic deep-freezer, then when they have frozen they can be floated in the pool to cool it down. Keeping sunshine off the pool by shading it will help too. Floating thousands of white ping-pong balls on the pool will reflect sunshine away and prevent the pool heating up.
Why do you get cold when you get in a swimming pool?
You feel cold after being in water because you are wet. Your body begins to evaporate the water so that you can become dry again. Where does the energy ( heat ) to evaporate all that water come from? That's right, your body.
Why does water feel cold in a summer pool?
The fact that it is in such close contact to the earth, the surface of which is cold compared to the air.
Is the a water resistant Swimming Pool Summer Party Tableware Set?
Yes, there are water resisitent Swimming Pool Summer Party Tableware Sets.
Can a concrete pool pop?
If you mean can a concrete pool pop up out of the ground then the answer is Yes it can. All you need is an empty or partially empty concrete pool and a lot of ground water around it once the ground water around the outside of the pool builds up enough the pool will start to float. I have seen it happen several times over the years. To avoid this happening most pools have a hydrostatic valve fitted in the bottom of the pool to allow ground water into the pool when there is a build up of water pressure outside the pool it flows into the pool to stop it from floating.
How many gallons of hot water do you need to add to heat your 4' by 15' pool?
It depends on many factors. Some of them are:how deep the pool is;how cold the pool water is;how hot the hot water is;how cold the air is;how cold the surrounding ground is;how windy it is; andhow warm you want the pool water.
Why is your new pool rough on all surfaces?
What type of surface is it? Concrete, Vinyl or fiberglass? If you have a vinyl or fiberglass pool and it is rough it is probably calcium that has precipitated out of the water you will need to have your pool water analyzed by a professional swimming pool company. If your pool is concrete it could be calcium also or it could be an etching of the concrete both are related to water chemistry and the same professional analysis would need to be performed to resolve the issue.
Can you get a cold in a salt water pool?
Yes.
Will cold water affect the plaster?
Pool plaster in generally not affected by cold water, cold water above freezing of course.
Can areas of exposed concrete on the bottom of a gunite or plaster pool be repaired with water in the pool?
No, because gunite will not dry if it is constantly being mixed with water. Drain your pool first.
If you lived in an area with very cold winters should water be kept in you outdoor pool all winter Why or why not?
No, water should not be kept in your pool all winter. When it gets cold enough, the water will freeze. When water freezes, it expands. So when the water in your pool freezes and expands your pool will be ruined.
How much water can saftley be draimed from an inground pool?
it depends on what the pool is made of if it is concrete then all of if its carbon fiber then about half of it.
Is pool a concrete noun?
Pool can be both a concrete noun and an abstract noun. As a concrete noun, it means a man-made body of water intended for activities or sports, such as a swimming pool or a wading pool. As an abstract noun, it refers to the concept of an otherwise-diverse group that shares some defining common characteristic: such as a pool of job candidates, an office betting pool, or even a pool of good ideas.
How do you find a leak in a concrete salt pool. tested all the lines and they are fine. It's a concrete pool and we switched to salt system 7 years ago. Could cement become porus enough and lose water?
The first thing to do is make sure you have a leak. and it is not just evaporation that is giving you your problem. you can do this by just taking a bucket and filling it with pool water. mark the water level in the bucket and in the pool. Stand the bucket next to the pool without disturbing the pool for a day or two. If the distance to the water level mark you made is the same in the pool as it is in the bucket then you don't have a leak and you are just loosing water to evaporation. if the distance to the water level mark in the pool is bigger then you are losing water somewhere else as well. I have had a concrete salt water pool for close to twenty years and it is still sound. I have had some problems wit pipes before though.
