Is your apartment or house so cold that you can see your breath?  Does it feel like the AC is set too high, even if it’s currently warmer outside than inside?

If yes, then you’re not alone. 66 degrees Fahrenheit feels unreasonably cold for many people (myself included). It’s about 18.9 degrees Celcius. It’s uncomfortable inside.

When this happens, it seems like an air conditioning problem, doesn’t it?

But in most cases, the AC isn’t actually to blame.  66 degrees often is simply too cold for the building itself.   How can that be possible?

Well, insulation plays a key role.  The thicker the insulation, the warmer your apartment will feel at a given temperature.

So if you’re living in an old building with no insulation, then even 65 degrees Fahrenheit might be too cold for you because it doesn’t have as much insulation as a newer home or apartment would have.

Is 66 degrees cold enough for a sweater?

As long as you have enough insulation, it’s fine to wear a sweater at 66 degrees Fahrenheit. But if your home doesn’t have the proper insulation, then you’ll need to use more heating than normal to keep warm in an older building.

Is 68 degrees cold outside?

68 degrees Fahrenheit is 20.5 degrees Celsius, so it’s neither hot nor cold outside. It’s comfortable for most people; if you’re planning to spend time outdoors, go ahead and do it in 68 degree weather without worrying about overheating or feeling too cold. If there’s a bit of wind going and you’re in the shade, it can feel a bit cold. You might want to pack a sweater.

Is 66 degrees even colder than 68?

Yes, it is. At 66 degrees Fahrenheit, you’ll start to notice the cold outside. It will be less comfortable for people who are sensitive to an indoor temperature of 66 degrees than it would at 68 degrees. However, there’s nothing wrong with staying outdoors in weather that’s about 20.5 degrees Celsius. If you’re planning on spending some time outside at night, go ahead and do it; just make sure you bring a jacket or extra layers so that you stay warm while you’re out there. 

How many degrees is considered very cold?

About 25 degrees Fahrenheit, which is about -4 Celsius. This temperature isn’t too cold for most people, but you’ll want to bundle up a bit if it’s going to be a windy or a particularly chilly day. Also I would recommend wearing a scarf, hat and gloves. Just in case.

What should I wear in 66 degree weather?

It doesn’t even feel like fall here today in Midtown. It was a nice 65 degrees + the sun was out. I wore jeans, short sleeve shirt & sneakers. Don’t know what this means for Christmas but you can always layer up with leggings underneath if it’s really cold.

Alternatively, pack a sweater just in case the sun can’t make it through the clouds or you know you’ll be outside after sunset.

Is 66 degrees too cold for a baby?

It depends on how many clothes the baby is wearing. Make sure they’re not too warm or too cold. 66 degrees is alright for one layer of clothing, but make sure to check on your kid every once in a while.


66 degrees Fahrenheit feels too cold for most buildings because insulation plays a key role in how warm an apartment or house feels. If the building doesn’t have enough insulation, it can be very uncomfortable at a temperature of 66 degrees Fahrenheit. However, you’ll only need to add more heating if your apartment was built before good insulation practices were established or someone has been careless about putting in proper insulation.

If you’re living in an old building with poor insulation, then even 65 degrees Fahrenheit might seem too cold for you because it doesn’t have as much insulation as a newer home or apartment would have. So if you live in Detroit and your thermostat says 64 but you feel like it’s colder than that, remember that the building itself doesn’t have as much insulation. If a building has a lot of windows and poor insulation, then windows with curtains can help to maintain the temperature inside the building.

68 degrees Fahrenheit is neither too hot nor too cold outside for most people. However, some people might feel more comfortable at temperatures that are warmer or cooler than 68 degrees Fahrenheit.

For example, if you’re wearing long sleeves on a windy day next to the ocean, it could feel colder than 68 degrees Fahrenheit because there’s some wind and maybe some clouds blocking out some of the sun’s warmth. As long as you bring a sweater and/or sunscreen and don’t plan on staying outdoors past sunset, 68 degrees Fahrenheit won’t be too cold for you.
