why is well water cool in summer and warm in winter?

its not like that , but according to HVAC data , the temp. underground is constant about 10 degrees celsius , so in summer its hot , then we find the water cooler , and in winter , the air temp. may be zero , so the water is hotter

water freezes at 32 degrees Fahrenheit, and 0 degrees Celsius\n\nthe colder the faster

All wells have a fresh water spring at the bottom. The water that enters is free to exit, and fresh water from the spring  flows in to replace the water that flowed out. \n\nThe water that is in a well is not exactly stagnant.\nThe water under the  ground is also pure because it is constantly moving through the silt and gets filtered. So the water that comes in is also pure and 'fresh' (though its been around for quite a while!).

warm water dissolves ice faster than warm air because it can transfer and absorb heat faster than warm air of the same temperature

Salt will lower the freezing point of water. That is why the use in on the roads in winter.

The body regulates our internal temperature in reference to an outside source (in this case the warm water). Your blood vessels going to your extremities are dilated, you sweat slightly more, and in some cases metabolism decreases because it produces heat. \n\nBy the way, the water does cool when it comes in contact with our body. The first thing that happens is it evaporates, because it uses the heat from our body to go from a liquid to a gas (evaporation). Then, it condenses (goes from gas to a liquid) back down to the bathtub because the air temperature is cooler than our body.

A well is a man-made place for getting water from the earth.  A spring is a natural place where underground water comes to the surface

Well, there are actually a number of answers to that question. \n1) There are underground springs and water tables, which are why people had wells, and some folks still do today. Most western states have wells that reach into actual rivers that run beneath the surface, approx. 180 feet down. There are also windmills that pump water from underground springs and such.\n2) The polar caps are also almost 85% fresh water, and as they are slowly melting they are even now effecting the tides and current flows. Due to the changing salinity in the oceans, the Gulf Stream for one is already altering its course slightly..\n3) As the water began to lower, it was also evaporating, enriching the atmosphere with an increase of moisture. Thus, making the upper levels of the atmosphere richer, and raising the oxygen levels. Believe it or not, water has a direct impact on the air supplies.. Not many people realize that, but it's true.\n    Good luck with all your answers...

It doesn't.  The t(exp 4)(temperature difference to the 4th power) law works here.  The higher temperature water will cool faster than the cooler water, however, when it reaches the temperature that the cooler water was in in the first place, it will cool at the same rate the cooler water cooled with.

Water distributes heat much faster than air can, thus, if your are warmer, it will absorb your body heat.

in winter  the earth is far away from the sun as  compared to summer so we receive less heat and we feel cold in winters

Cold water has more dissolved gases in it than hot water.  Any dissolved solutes cause the freezing point of water to be lower than pure water with nothing dissolved in it.\n\nThis means if your power goes out in the wintertime and it is about 32 degrees F outside, the water in your hot water pipes is more likely to freeze than the water in your cold water pipes.  This is because the freezing point of the water in your hot water pipes is higher than the freezing point of the water in your cold water pipes.\n\nSpeed isn't being considered here.  The cooling process is assumed to be slow so that the pipes are in thermal equilibrium with surroundings.\n\nAlso check out this link.  It is from the Alaska Science Forum.  They can explain the water pipes problem more correctly than me and they have more personal experience with the phenomenon.\nhttp://www.gi.alaska.edu/ScienceForum/ASF4/440.html

well, it all depends. If you live in like, california it can be anything from really weird weather like hot one week and a blizzard the next, and if you live in like south america, in peru, the waters get really warm. that's just a few of them.

One thing I know, salt reduces the freezing temperature of water, its why ppl use salt on snow and ice. Not because it melts it, but because it reduces the freezing temp.

It's mainly due to the effects of ocean currents.  Water has a much higher heat capacity than dry air, so it takes longer to heat and cool.  So climates near major bodies of water tend to be more mild in both the summer and the winter than inland climates.

The answer to this is made tougher by the fact that the water will be freezing.  I mean how can you answer a question where the water is ice cold and use the data provided at STP?  Think you need to either re-read your question or provide a little more info.

I think the key words in your question are "at room temperature".  See, room temperature is less than body temperature.  Heat energy wants to go from a higher temp region to a lower temp region.  But, water absorbs heat energy at a faster rate than air.  So, the cooling feeling (or transfer of heat away from your body into the surrounding medium) is greater in water than in air.  Now, turn on a fan and have more air, thus more cooling medium moving over you taking heat away and it will feel cooler even inf the air is at the same room temperature.
