Wireless pool thermometers are either digital or solar-powered. Both kinds are waterproof since you need to be able to put the thermometer in a pool. Most people like to leave their wireless thermometer in the pool all the times so that they can swim up and check it anytime; others prefer to keep the thermometer in their pool supply storage cabinet and then bring it out to check the pool temperature. Either method you choose will work.
The only negative part about keeping the thermometer put away is that every time you take it out to check the temperature, you have to wait several minutes for the thermometer to configure its reading. With keeping the thermometer in the pool, you never have to waste extra time, since it already has the temperature ready for you. Solar-powered vs. digital pool thermometer will play a part in this decision as well.
Solar-Powered Pool Thermometers
Solar-powered pool thermometers run on the power of the sun rather than on batteries. You might say that solar-powered pool thermometers are the eco-friendlier option since when they get thrown away, there isn’t a battery to dispose of afterward.
Having a solar-powered pool thermometer will require you to keep it in the pool as much as possible since it needs the sunlight. You could keep it on your pool deck, out of the water, but that would be pointless if it needs to be in the sun; so, you might as well keep it in the water. No harm can come of it.
Digital Pool Thermometers
Digital pool thermometers rely on a set of batteries for their power. The main reason you would want to use a digital thermometer is that you want to keep it stored outside of the pool. If you already have many inflated objects in your pool and other toys, an added thermometer will increase the amount of clutter.
Another problem is that if you have kids that swim in your pool often, the thermometer could break due to excessive playing. The last thing you want to do is to buy another pool thermometer. It is best to save your money and take the necessary precautions by putting the pool thermometer away while people are visiting.
Standard Pool Thermometers
Not all wireless pool thermometers need power. Some of them work the same way as glass thermometers that you use to measure a person’s body temperature. This is the cheapest option for a pool thermometer since it has a scale rather than a digital number on a screen.
Correct Water Temperature in Chlorine Pools
The temperature of a pool has a more significant impact than just on how cold you feel while you swim. When it comes to algae and bacteria, they love to live in warm water. Even if you have an adequate level of chlorine and pH in your pool, they will find a way to thrive more than usual because of the warmth. This is the case for any place or thing; like when frozen meat thaws out on an exposed surface and becomes too warm, bacteria will start to grow and multiply; it is the same type of situation. Swimming pools are supposed to be a safe place to swim, but the water goes bad quickly if no one is taking care of it. And as a pool owner, one of your important jobs is to check the pool temperature every once in a while, especially before bringing over guests.
Prevent bacteria and algae by keeping your pool below the following temperatures:
- Maximum Commercial Pool Temperature – 82 degrees Fahrenheit or 28 degrees Celsius.
- Maximum Recreational Pool Temperature – 84 degrees Fahrenheit or 29 degrees Celsius.
How to Lower Pool Temperature
If you live in a warm climate, and you notice that the temperature of your pool has reached an unacceptable level, there are ways to keep it cooled.
One way you can reduce the temperature a bit overall is by removing any trees or shrubbery that surround the pool, since these trap heat. Leave trees alone that are providing shade over the pool. Otherwise, take out the others, especially if they are blocking the wind.
The second idea you can use to keep your pool water temperature low is to install a reverse-cycle heat pump, one of the most effective options. These pumps use a refrigerant to maintain a set temperature in the pool by cycling water through itself. You can use a reverse-cycle heat pump for lowering or raising the pool temperature, which means if you want to use it in the winter to create a heated pool, then you can! Pumps like these aren’t cheap, but they are great to have.
Lastly, connect a fountain to one of the return jets in your pool. It sounds odd, but it works fast and is a lot cheaper than buying a heat pump. When water settles, that is when it builds up the most heat. A water fountain adds air to the pool water while it is working, which stirs up the water and provides an escape for trapped heat. You should try using a water fountain in your pool first before trying the other two options unless you are unable to because you don’t have jets in your pool.
Best Wireless Pool Thermometers
When you are choosing the best pool thermometer, find one that gives accurate temperature readings, is durable, and has a pleasant appearance to you. Since the temperature gauge might be in your pool most of the time, you want something that you will enjoy seeing in your pool, and that doesn’t look bad or cheap.
Durability is the second most important factor. Water, especially chlorinated water, tends to break down materials over time. Even plastic has some noticeable effects in chlorine, like losing color or becoming fragile.
The most crucial element is the ability of a pool thermometer to give accurate readings. There may be some debate, but no one pool thermometer type is more accurate than the others.
Sometimes the standard thermometers are more reliable because of how long they are; the surface of pool water is usually colder than below, so if the thermometer reaches down that far, then it is measuring both the surface temperature and temperatures that are at least a foot below.
1. Floating Pool Thermometer
Customer Rating: 5 out of 5 stars
Thermometer Type: Standard
This Floating Pool Thermometer reads the temperature in both Celsius and Fahrenheit. It measures between 32- and 120-degrees Fahrenheit, and between 0- and 40- degrees Celsius, which is all you will need for a pool. If it tries to read anything hotter than the max, the thermometer probably broke, and you should buy a new one unless the area you live in produces extremely high temperatures.
But, remember, to keep your pool free of bacteria, you want to keep the water temperature under the recommended levels (see maximum temperatures in the Correct Water Temperature section above). Buying a high-quality pool thermometer is one of the key ways to prevent algae and bacteria.
2. Daveyspa Floating Pool Thermometer
Customer Rating: 4.3 out of 5 stars
Thermometer Type: Standard
The Daveyspa thermometer looks more like a decoration than a thermometer, which is what some people prefer. Those people want to put it in their pool and forget about it until they need to check the water. It is one of the cheaper options as well; it’s not cheap as in cheaply made, but it won’t cost you any more than one that is.
3. Finerplan Wireless Solar Power Floating Pool Thermometer
Customer Rating: 4 out of 5 stars
Thermometer Type: Solar-powered
This Finerplan Wireless Pool thermometer is one of your solar-powered pool thermometer options. There aren’t many solar-powered thermometers that have good reviews; this is the best one you will find. The floating thermometer connects to a digital reader that you can hold or mount on a wall, which makes it easy to view the temperature without having to bend down and reach into the pool to grab the floating thermometer.
It is a good option if you have back problems or another physical ailment that would prevent you from bending over or reaching into a pool.
4. 3 in 1 Water Quality Tester, TDA Meter, and Temperature Meter
Customer Rating: 4.5 out of 5
Thermometer Type: Digital
This pool thermometer functions as much more than just a temperature gauge. On the end of the reader is a cap that comes off, and then the end is what you put into the water. It measures TDS (total dissolved solids), EC (electrical conductivity), and water temperature. These types of testers aren’t for only pools; you can use them in aquariums, drinking water sources, or any other bodies of water. It runs on battery life which is on the opposite end of the tester.
Thermometers like this are much less convenient than your other options since you have to take the reader out, take the cap off, place the end of it into the water, and wait for it to tell you the temperature, rather than just viewing it on a standard or a solar-powered pool thermometer. However, this is a good type of thermometer if you need something that you can use on both a pool and an aquarium.
5. Ambient Weather Wireless Floating Pool and Spa Thermometer
Customer Rating: 3.8 out of 5
Thermometer Type: Digital
The Ambient is more than it appears. It is a digital pool and spa thermometer, but it runs on a frequency, which is 915MGz, and has seven channels so that you can connect it to other devices that on the same frequency or connect over Wi-Fi. There is a Remote Monitoring Weather Station that you can buy on Amazon that connects to this thermometer and shows you the temperature and humidity.
The weather station comes with an app, a digital display, a humidity detector, and the floating thermometer. You can buy the thermometer using the link above, or buy the entire set using the link provided below. The full Ambient Weather Station is much more expensive, but it makes the thermometer more convenient. Since you can purchase the floating thermometer separately, you can connect it to other compatible devices as well.

How Often Do You Check Pool Temperature?
Checking the temperature of your pool should be a part of your daily pool maintenance routine. Not every day do you have to do a complete cleaning of your pool, but you can at least do a quick test of the chlorine and the pH level, and then take a glance at the thermometer to ensure that the temperature is in a safe range. Of course, if you notice any problems or if the temperature is in a bacterial zone, you will have to deal with it right away so that it doesn’t turn into something much worse.
Once you find a pool thermometer that you like, before you buy it, check to make sure that it measures temperature in the correct degree measurement, Celsius or Fahrenheit. Also, look at what type of thermometer it is and if it is digital, do you need to buy batteries for it, or does it come with them?
Look at the reviews of other customers to see how well the thermometer worked for them and how long it lasted. All five of these best wireless pool thermometers have a significant number of reviews that you can view, click the link below the picture to see them and the price.
