It’s that time of year again when gardeners start to worry about their hose pipes freezing. Every winter, people post on social media asking what the temperature threshold is for a hose to freeze. Unfortunately, there is no definitive answer. The temperature at which a hose will freeze depends on many factors, including the type of hose, the weather conditions, and the length of the hose. In this blog post, we will explore the different factors that contribute to whether or not your garden hose will freeze. We will also provide some tips for preventing your hose from freezing in cold weather!
What Temperature Does It Take To Freeze A Garden Hose?
Ice, in turn, is the enemy of garden hoses. When the water inside the hose freezes, it expands and can crack or split the hose open. This happens because water is a strange substance; it actually expands when it freezes instead of contracting like most other materials. So if you’re ever wondering what temp a garden hose freezes, now you know!
32 degrees is cold, but it’s not unheard of during wintertime in many parts of the country. If you live in an area that regularly dips below freezing at night, then you’ll want to take steps to protect your garden hose (and any other outdoor plumbing) from the cold. One way to do this is to store your hose indoors overnight. If that’s not possible or practical, then you can try wrapping it in an insulating material like old blankets or towels. Most of the time, however, this should just be good enough to keep your garden hose from freezing solid.
Of course, even if you take all of these precautions there’s always a chance that your garden hose could freeze solid at some point during the winter. [1]
Is it acceptable to leave your garden hose outside over the winter?
Here are some answers to questions about garden hoses and freezing temps.
During the winter months, garden hoses should be stored indoors to avoid prolonged exposure to chilly temperatures. However, if you must leave your hose outside for any reason, there are a few things you can do to protect it from freezing.
First, try to keep the hose away from any sources of direct heat, such as a furnace or hot water heater. These can cause the water inside the hose to expand, which can lead to bursting.
Next, insulate the hose by wrapping it in something that will hold in heat, such as old blankets or towels. This will help keep the water inside the hose from freezing. Besides, you may be interested in how to heat water from a garden hose.
Finally, if you know the temperature is going to drop below freezing, disconnect the hose from any faucets or spigots and allow it to drain completely. This will help prevent the water inside the hose from expanding and bursting the hose. [2]
3 Effective Ways to Keep Your Garden Hose from Freezing

You can use your garden hose without fear of it freezing if you simply follow these easy instructions! [3]
How Do You Unfreeze a Frozen Hose?
If you find yourself with a frozen garden hose, there are a few things you can do to unfreeze it. First, try using warm water to thaw the hose. You can also use a hairdryer on the low or medium setting, being careful not to melt the hose.
Finally, if none of these methods work, you may need to replace the entire hose. [4]
How to Avoid Freezing Your Garden Hose?
Here are a few tips:
- Bring your hose inside overnight: This is probably the simplest solution and one that will work even in very cold temperatures. If you can’t bring the entire hose inside, at least bring in the portion that is exposed to air.
- Use a heated water bowl: This is another easy solution that can be used even when temperatures are extremely cold. Simply place a bowl of warm water next to your outdoor faucet and run the hose into it for a few minutes before use. The warmth from the water will help prevent the hose from freezing.
- Use a hose heater: This is a more expensive solution, but it’s one that will work even in the most extreme cold. A hose heater is a small device that attaches to your hose and uses electricity to keep the water inside from freezing.
With a little bit of planning, you can easily avoid having your garden hose freeze in cold weather. By taking some simple precautions, you’ll be able to keep your hose in working order all winter long. [5]
Comparison of Garden Hose Freezing Points based on Material and Water Pressure
As winter temperatures drop, garden hoses can be at risk of freezing, which can cause damage to the hose and hinder its functionality. The freezing point of a garden hose can depend on several factors, including the material of the hose and the water pressure. This table compares the freezing points of garden hoses made from different materials and subjected to various water pressures.
| Material | Water Pressure (psi) | Freezing Point (°F) |
|---|---|---|
| Rubber | 0 | 32 |
| Rubber | 20 | 24 |
| Rubber | 40 | 14 |
| PVC | 0 | 32 |
| PVC | 20 | 20 |
| PVC | 40 | 12 |
The table includes three columns: Material, Water Pressure (in pounds per square inch, or psi), and Freezing Point (in degrees Fahrenheit). The Material column lists two types of garden hose materials: Rubber and PVC. The Water Pressure column lists three levels of water pressure: 0 psi, 20 psi, and 40 psi. The Freezing Point column shows the temperature at which water will freeze inside the garden hose based on the material and water pressure.
As shown in the table, rubber hoses generally have a higher freezing point than PVC hoses. At 0 psi water pressure, both rubber and PVC hoses have a freezing point of 32°F, which is the freezing point of water. As the water pressure increases, the freezing point of both materials decreases. However, the rubber hose consistently has a higher freezing point than the PVC hose at all water pressure levels.
It’s important to note that these freezing points are only estimates and can vary depending on other factors such as air temperature, sunlight exposure, and the duration of exposure to freezing temperatures. It’s recommended to always drain and store garden hoses in a dry, protected area during the winter months to prevent damage from freezing temperatures.
When Will a Garden Hose Freeze: Comparison Table
This table provides a comparison of various indicators related to the freezing temperature of a garden hose. Knowing when a garden hose will freeze is essential for preventing damage and ensuring proper garden maintenance during colder months. The data below will help you understand the factors affecting hose freezing and make informed decisions to protect your garden equipment.

| Possible Bursting | -6°C | 21.2°F |
| High Risk of Bursting | -9°C | 15.8°F |
| Highly Likely to Burst | -12°C | 10.4°F |
In the table above, we have listed various indicators along with their corresponding freezing temperatures in both Celsius and Fahrenheit scales.
- Water Begins to Freeze: At around -0.5°C (31.1°F), water molecules in the garden hose start to form ice crystals.
- Ice Crystals Form: When the temperature drops to approximately -2°C (28.4°F), ice crystals begin to form and spread within the hose.
- Water Solidifies: As the temperature reaches -4°C (24.8°F), the water inside the hose solidifies and becomes more prone to damage.
- Possible Bursting: At about -6°C (21.2°F), the risk of the hose bursting due to the expansion of freezing water increases significantly.
- High Risk of Bursting: Around -9°C (15.8°F), the hose is at a high risk of bursting, causing potential damage to the garden hose and water supply.
- Highly Likely to Burst: When the temperature drops to -12°C (10.4°F), it is highly likely that the garden hose will burst if water is left inside.
Keep in mind that these freezing temperatures are approximate values and can vary depending on factors such as water pressure, hose material, and exposure to wind chill. To protect your garden hose from freezing and potential damage, it’s best to disconnect it from the water source and store it in a warmer place during colder weather.

How long should I leave the hose connected to the pump? What temperature should it be?
These are common questions we get asked here. The answer, unfortunately, is not as simple as one might hope. While the average person might think that a garden hose would freeze at the same temperature water does, that’s not always the case – particularly if your hose is exposed to direct sunlight or other sources of heat during freezing weather.
There are a number of factors that can affect how quickly and easily a garden hose freezes in cold weather. These include:
- The type of material the hose is made from. Some hoses are more resistant to freezing than others.
- The thickness of the hose walls. Thicker hoses will take longer to freeze than thinner ones.
- The amount of water in the hose. A hose that is partially filled with water will freeze more quickly than one that is completely empty.
- The size of the hose. A small garden hose will freeze more quickly than a large one.
- The temperature of the water in the hose. Colder water will freeze more quickly than warmer water.
- The amount of time the hose is exposed to cold temperatures. A hose that is left outside in the cold for a long period of time is more likely to freeze than one that is only exposed to the cold for a short period of time.
Will pipes freeze at 30 degrees?
The answer is, it depends. If the ground around your pipes is well-insulated, then your water pipes are less likely to freeze. But if the ground isn’t insulated, or if your home is in a cold climate, then your water pipes could freeze at 30 degrees Fahrenheit.
If you think your water pipes might be at risk of freezing, there are some things you can do to prevent it from happening. One option is to wrap them in insulation material. Another option is to keep a space heater near the pipe so that the area around it stays warm.
What happens if you leave a hose connected to the water while it freezes?
The water in the hose will freeze, and as it does, it expands. This can cause damage to the hose or even burst it.
Is it possible for moving water to be colder than 32 degrees?
Yes, it is possible for moving water to be colder than 32 degrees. The air temperature does not have to be below freezing for this to happen. If the air temperature is above freezing, and the water is moving quickly enough, the water can actually freeze.
Garden hoses are particularly susceptible to freezing because they are often left outside and exposed to the elements. When water freezes in a garden hose, it expands and can cause the hose to burst. This can lead to costly repairs or even replacement of the hose.
How can I prevent my garden hose from freezing?
