Does water evaporate more in winter?
The higher the temperature of the water, the higher the vapor pressure. As the temperature of your pool's water gets colder, the differential pressure between the water and the air increases. This speeds up the rate of evaporation.
How does water evaporate when it’s cold?
Yes, cold water can evaporate. Water is made up of tiny molecules that are always moving around. The constant movement builds up energy that eventually causes water to evaporate.
At what temperature does water stop evaporating?
The boiling point of water is 100 deg C at 1 atm. This is the temperature that liquid is in equilibrium with its gas phase. And you are right that below this temperature (at 1 atm) water should not vaporize.
Does water dry in the cold?
John – Even when it's very cold, washing will still dry, but it may dry so slowly that it really just isn't worth it. The reason washing dries is because water evaporates from it.
Is it normal to lose pool water in winter?
An uncovered pool will lose water in the winter to evaporation in the same way it does during the summer. But the water loss is only about a quarter-inch on average during a 24-hour period when the pool is not in use. An uncovered or covered pool can have problems in the plumbing lines or pump.
Should I add water to pool in winter?
Although it may seem scary to leave water in a pool during freezing temperatures, you can actually damage your pool more by removing too much water. Your water should only be drained so it sits just below the skimmer and jets. This helps make sure that no water can get into the pumping system.
Can water evaporate below freezing?
If an ice cube is stored in a freezer could it evaporate given enough time? Is there a temperature below which water cannot evaporate (even just a little)? For the first part, ice can sublimate at freezer temperatures, so yes, it can (and does) slowly evaporate.
Does water evaporate overnight?
The differential that occurs between the pool water temperature and the air temperature on late summer nights causes water to evaporate at an accelerated rate. In some cases you might see a water level difference of 1-3 inches overnight. Depending on the size of your pool, that can be over 500 gallons of water loss!
Does water evaporate faster in winter or summer?
Evaporation rates are higher at higher temperatures because as temperature increases, the amount of energy necessary for evaporation decreases. In sunny, warm weather the loss of water by evaporation is greater than in cloudy and cool weather.
Should you water in the winter?
Once plants go dormant for the year many people believe that they need nothing until spring, but that isn't always the case, especially in years with low or no snow or rain throughout the winter months. Winter watering is essential in dry winter years.
How do I know if my pool is leaking or evaporating?
If the water went down a similar amount in the pool as well as the bucket, then you lost water due to evaporation. If it went down more in the skimmer and not much at all in the bucket then you have a pool leaking.
How do I know if I have a pool leak?
If you see a puddle of water near your pool and it hasn't rained in some time or no one has gone swimming, this is a sure-tell sign of a pool leak. If you stand by your pool make sure you feel the nearby grass. If the grass feels mushy or uneven, this is a sign of an underground leak.
Is it normal for a pool to lose water over winter?
It is quite common for a pool to lose water over the winter. There are several reasons why a pool could lose hundreds of gallons of water gradually over the colder seasons. If the pool water continues to gradually decrease, the first and most common reason may be a small hole or tear in the pool liner.
How much water will evaporate from a pool in the winter?
about a quarter-inch An uncovered pool will lose water in the winter to evaporation in the same way it does during the summer. But the water loss is only about a quarter-inch on average during a 24-hour period when the pool is not in use. An uncovered or covered pool can have problems in the plumbing lines or pump.
Does water evaporate eventually?
The heat in that water results in some molecules moving fast enough to escape into the air, that is, evaporate. No additional source of energy is required for evaporation, and the water does not need to reach the boiling point to evaporate. As we've seen, water will evaporate at room temperature.
At what temperature does evaporation occur?
Evaporation can occur at any temperature; it does not require the liquid to be at its boiling point. (Evaporation is faster at the boiling point than at lower temperatures.)
At what time does water evaporate?
According to these web sites, the average time a water molecule spends in the atmosphere is 8-9 days. This is pretty fast! So on average, it takes just 8-9 days for a water molecule to evaporate, enter the atmosphere, and then leave it again as rain.
Is it normal to lose pool water over the winter?

If the pool water continues to gradually decrease, the first and most common reason may be a small hole or tear in the pool liner.
Why does evaporation decrease in winter?
The hot summer sun warms the water throughout the warmer months. In the winter, when a cold arctic blast sweeps across the surface the cold air sucks heat out of the lake in the form of evaporating water.
How often should I water in the winter?
Watering once or twice a month is usually enough to keep your lawn moist throughout the winter.
Do trees drink water in the winter?
In winter, a dormant tree may look still and lifeless but inside and below ground it's active, maintaining the chemical changes that control dormancy. Because both tree roots and a tree's internal functions are still working during dormancy, a tree in winter needs regular water and oxygen.
Why is my pool losing water in the winter?
Another reason for a pool to lose water over the winter is due to the harsh elements. Ice, snow, and water can accumulate on top of the pool cover. When too much weight forces the pool cover into the surface of the pool, water may rise up and over the pool sides. This is called displacement.
How often should I need to add water to my pool?
Normally pools see ¼ – ½ inch loss of water per day due to evaporation. This is roughly 2 – 4 inches per week. For a normal sized pool you will loose 25,000 to 50,000 gallons of water per year due to evaporation. This means I was putting a hose in the pool every 7-10 days to fill the pool.
Where do most pool leaks occur?
Most pool leaks are not in the underground plumbing, although it's every pool owner's worst fear, a large backhoe coming in and ripping up the pool deck. It does happen occasionally, that a leak occurs at a pipe connector under the pool deck, or beneath the skimmer, but repair rarely involves a backhoe.
Why is my swimming pool losing water?
Pools lose water gradually, so water-loss can often be left undetected until it escalates into a serious problem. It's natural for pools to lose water due to evaporation, varying in speed depending on the humidity, temperature, wind conditions, use of pool heater, or the rate of use of the pool.
Why is my pool half empty after winter?
Another reason for a pool to lose water over the winter is due to the harsh elements. Ice, snow, and water can accumulate on top of the pool cover. When too much weight forces the pool cover into the surface of the pool, water may rise up and over the pool sides. This is called displacement.
Should I add water to my pool in the winter?
Inground Pool Winter Tips and Guidelines Mesh Safety Cover – If you have a mesh safety cover and a chlorine pool, you'll want to add 2 gallons of liquid chlorine to your pool water every 2 weeks starting 3-4 weeks after we close your pool and until outside temperatures get consistently colder.
Does water evaporate below freezing?
If an ice cube is stored in a freezer could it evaporate given enough time? Is there a temperature below which water cannot evaporate (even just a little)? For the first part, ice can sublimate at freezer temperatures, so yes, it can (and does) slowly evaporate.
Does water evaporate faster in hot or cold temperatures?
Although water can evaporate at low temperatures, the rate of evaporation increases as the temperature increases. This makes sense because at higher temperatures, more molecules are moving faster; therefore, it is more likely for a molecule to have enough energy to break away from the liquid to become a gas.
Should you water during the winter?
Choose days when no snow is on the ground and the soil isn't frozen. In cold weather, water should be trickled slowly into the soil. Water only when air temperatures are above 40 degrees F. Apply water at mid-day so there is time to soak in before possible freezing at night.
