Do Basements Get Hot In The Summer? (Explained!)

There’s no question about the houses getting hot in the summer, right? Unless you’ve got powerful cooling systems and impeccable quality insulation, you can stop thinking about the summer hotness for a while.

Some homeowners can’t imagine living inside an oven, which happens when the house does not have proper insulation.

Likewise, if you visit the basement regularly throughout the day, then the summer hotness can catch up to it as well. Here’s what homeowners should know about how summer temperatures can affect your basement.

Basements Get Hot In The Summer

Here’s if Basements Get Hot In The Summer:

Basements are usually damp places that don’t easily get affected by temperature. However, it soon catches up on temperature changes, turning the overall atmosphere differently.

You can try various methods and hacks to keep your basement cool during a harsh summer.

Opting for high-quality cooling systems, using outdoor shades, using no-heat appliances, and so on can help keep the basement cooler.

You can try many different tasks and ideas to keep your basement cooler. The only issue is that the basement, especially its walls, takes longer to catch up on the temperature.

But, if you use the right methods, you can prevent the basement from getting uncomfortably hot. And, it’s even more important because basements take time to catch up on the outdoor temperature.

So, you can assume that the basement will be cooler than the outdoors in summer while being warmer during the winter.

That’s mainly because the frequency of windows and doors isn’t the same for a basement compared to other rooms and floors of a home.

The transfer of heat and temperature also doesn’t take place as readily as it does in other rooms of the house. Basements are usually below ground level and that ensures a cool and comfortable environment.

But, just as the basement remains cooler for longer despite hot temperatures outside, it can remain hot for longer if you fail to use the right methods to cool it down.

Do Basements Ever Get Hot?

Yes, when harsh climates strike, even the room of your house below ground level tends to lose its cool! You can experience hot temperatures and unbearable conditions in your basement if the summer is at its peak and you’re doing little to nothing to preserve its cooling.

Indeed, basements are usually cooler than the rest of the house because they’re below ground level. Therefore, the harsh sun rays and temperatures take time to reach there.

Regardless, you have to maintain a consistent temperature. Many homeowners use the basement for recreational activities, family get-togethers, or to do their laundry simply.

It can be unbearable to work or enjoy anything down there if it’s too hot. With the lack of the right insulation material and other framing components, the heat can transfer from other house parts down to the basement.

Once the temperature rises in the basement, it can be extremely difficult to cool it down naturally. Basements are enclosed spaces like rooms but they’re below the ground. That means basements lack appropriate means of keeping the temperature down, such as ventilation.

So, if a basement gets hot to an unbearable limit, you may have to abandon it and wait for it to cool down before going back. If you’re working or exercising in the basement, it can become extremely intolerable and inconvenient.

Basements do get hot but it’s entirely your choice as to what methods you choose to make them cooler. Once hot, it can take time for the basement to cool down naturally. But, you can always use air conditioning and ventilation facilities.

Will My Basements Stay Cool In The Summer?

You can keep the basements cool throughout the summer season even if they take on the hot temperature due to ill maintenance. Keep in mind that it takes some time for the basement wall, ceiling, and other parts to change according to the temperature.

You can use no-heating appliances such as bulbs that don’t emit any heat when used for lengthy periods. You can use outdoor shades to prevent direct sunlight from reaching the house’s walls or basement windows.

On the other hand, if you haven’t already, you can frame and insulate your basement. While you do that, you can opt for a cooling system that’s efficient and conserves energy, which will prevent your basement from getting hot.

Furthermore, you should know that if your basement has started feeling like a boiling pot, there could be water leaking beneath the floor.

Any faulty pipes or water supply components can result in leakage. It will affect the temperature inside the basement and cause it to boil over time.

On top of that, excess water presence and moisture buildup where direct sunlight doesn’t reach can promote mold growth. Also, excessive water buildup can adversely affect the structural integrity of your house.

What Temperature Should Basement Be In Summer?

The ideal temperature to remain comfortable in the basement during winter is 58-60 °F. And, in the case of carpets, it can be intolerable to stay in the basement when the temperatures rise.

I am wondering whether or not you should try to tweak the temperature of your basement? Well, it depends on the level of comfort and convenience you want.

You can take scheduled temperature readings to note whether or not your basement is getting hotter than usual. If yes, you can take action to reverse the effect and make it more hospitable for you and your family.

On the other hand, if the basement’s temperature appears tolerable and hospitable, you won’t have to budge a bolt from its place. Depending on your region and the season, the interior basement temperature can vary.

Also, it’s relatively true that basements not bothered by cooling or heating systems flow with the annual temperature as seasonal changes. But, every individual desires a different level of comfort.

So, make sure you address the temperature change best and use the right techniques to keep your basement cooler throughout the summer.

Are Basements More Humid In Summer Or Winter?

You should know that basements are considerably damper places than any other part of the house, except the bathroom.

In most US homes, water pipelines run beneath the basement floor. So, active water sources are right under your feet when walking around the bottom level.

So, with the onset of summer, the harsh temperatures with excessive humidity due to leaky or active water sources can cause intolerable living conditions in a basement.

Mold and mildew growth is also common in basements due to high humidity. Therefore, be on the lookout for mildew or any foul smells.


Do you realize the importance of water sources and moisture content in the basement? Excessive moisture can cause mold/mildew growth, while summer may bring harsh boiling temperatures and sunny days.

But, that rarely affects the basement as it’s below ground level. With the help of several tips and techniques, you can keep your basement cooler in summer and warmer in winter.
