How Cold is Well Water


Well water is typically colder than surface water because it comes from a groundwater aquifer, which is a layer of rock, sediment, or soil that holds water. The average temperature of well water is about 10 degrees Celsius cooler than the average temperature of surface water. In some cases, well water can be as much as 20 degrees Celsius cooler than surface water.

Assuming you would like a blog post discussing the temperature of well water: Have you ever taken a sip of water from the hose on a hot day and been surprised by how cold it is? The same principle applies to water that comes from a well.

Although the water in a well comes from underground, it is still affected by the temperature outside. In fact, well water is usually colder than surface water because it is less exposed to the sun. The average temperature of well water is between 50 and 60 degrees Fahrenheit.

However, this can vary depending on factors such as depth, location, and time of year. For example, shallow wells tend to have warmer water than deep wells because they are closer to the surface where it is warmer. Wells located in sunny areas will also have warmer water than those in shaded areas.

And finally, winter months will typically have cooler temperatures than summer months since there is less sunlight during winter. If you’re interested in finding out the exact temperature of your well water, you can use a thermometer to take readings at different depths and times of day. By doing this, you can get an accurate idea of what to expect when you take a drink!

Is Deep Well Water Cold?

Deep well water is typically cold, due to the fact that it comes from underground. The average temperature of deep well water is 50 degrees Fahrenheit. In some cases, deep well water can be as cold as 35 degrees Fahrenheit.

What Temperature is Water Underground?

Water underground can have a range of temperatures depending on the location and depth. In general, water a few feet below the ground is about 10 degrees warmer than the air above it in the winter and cooler in the summer. The deeper you go, the more constant the temperature becomes.

At depths of a mile or so, water temperatures are pretty constant year-round at around 50 degrees.

Do Wells Run Out of Water in Winter?

Just as rivers and lakes can freeze in winter, so too can groundwater. When the temperature dips below freezing, the water in underground aquifers can turn to ice. This process is called frost wedging or cryogenic weathering.

Frost wedging is one of the most important processes that break rocks apart over time. Although frost wedging can occur any time the ground temperature falls below freezing, it is most common and most effective in areas where water seeps into cracks in bedrock. The water expands when it freezes, putting pressure on the rock and causing it to crack further.

Over time, this process can create large fractures and even cause bedrock to fracture along preexisting joints or bedding planes.

What Temperature is Well Water in Michigan?

The average temperature of groundwater in Michigan is 10°C. However, this varies depending on the depth at which the water is found and the location within the state. For example, groundwater near Lake Superior tends to be cooler than groundwater found in southern Michigan.

Groundwater Temperature by Zip Code

If you’re interested in learning about the average groundwater temperature by zip code, you’ve come to the right place! In this blog post, we’ll provide detailed information on this topic so that you can have a better understanding of what to expect when it comes to temperatures beneath the ground. As mentioned earlier, average groundwater temperatures can vary significantly from one location to another.

This is due to a variety of factors, including the type of rock and soil that are found in an area, as well as the climate. For example, areas with a lot of granite tend to have cooler groundwater temperatures than areas with sandstone or limestone. Additionally, colder climates will generally have cooler groundwater temperatures than warmer climates.

Now that we’ve covered some of the basics, let’s take a look at average groundwater temperatures by zip code. We’ll start with some zip codes in the northern United States: Zip Code: 99501 (Anchorage, Alaska)

Groundwater Temperature: 37 degrees Fahrenheit Zip Code: 04401 (Bangor, Maine) Groundwater Temperature: 42 degrees Fahrenheit

Zip Code: 55701 (Duluth, Minnesota) Groundwater Temperature: 39 degrees Fahrenheit As you can see, there is quite a range in temperatures even within a small geographical area.

This just goes to show how important it is to know your specific location when it comes to determining the average groundwater temperature.


Most people don’t think about how cold their well water is until they take a shower in it or drink it. The average temperature of well water is 50-60 degrees Fahrenheit. This may not seem cold, but when you compare it to the 70-80 degree water that comes out of your tap, you can see the difference.

There are a few things that affect how cold your well water is. The depth of your well, the time of year, and the location of your well all play a role in the temperature of your water. In the winter, wells tend to be colder than they are in the summer because the ground around them is cooler.

If you live in a colder climate, your well will also be colder than if you live in a warmer climate. There are ways to heat your well water if you find that it’s too cold for you. You can install a point-of-use heater near your faucet or shower head or you can have a whole house heater installed.

These heaters will raise the temperature of your water so that it’s more comfortable for you to use.
