Knowing the temperature of your house and the outdoor environment is important. This information will let you adjust the air conditioner or heater with the utmost precision, which, in turn, will raise the level of your comfort. Furthermore, having an outdoor thermometer lets you know how to dress accordingly for a night out with your friends.
The top models have a sensor that you keep outside. That sensor then wirelessly transmits the temperature condition to your indoor monitor. Even more than that, they can provide you with humidity, wind speed, and various other useful reading.
This list of the best indoor outdoor thermometers includes models in different levels of features, price, and design.

Indoor Outdoor Thermometer Buying Guide
Here are the features we suggest looking for, along with some easy instructions on how to use your new thermometer.
Display Size
The bigger the display, the better. It’s nice to be able to glance at the monitor from across the room rather than having to walk up to it. Also, smaller screens are more inconvenient because it is harder to differentiate between information. With a bigger display, you will read everything clearly, and it will provide a lot of space to present all of the variables.
Backlight
Thermometers without a backlight are fine during the day, but after sunset, they are more of a hassle, especially if you put it outdoors. A backlight guarantees that you will always be able to read it, and things like glare or darkness won’t stand in your way.
Source of Power
Some thermometers on this list will work on batteries alone, others on AC. Even though battery models can be placed anywhere, thermometers with an AC power source ultimately prove to be a less expensive option. If you aren’t sure which one will serve you best, you can also choose the thermometer that can be used both ways.
Look
There are many different thermometers on this list. From the most sophisticated ones to dull-looking but solid budget models. You should think about where you are going to put it. If it is going into a living room, you may opt out for a more elegant model, compared to one going into the utility room.
Types of Thermometers
You will not want to choose the same thermometer for office and home. There are a few types that have different properties, so you’ll want to decide which features will serve you the best in which setting.
Analog Thermometers
These are the old-school bare thermometers that have only a bar that goes up and down, depending on the temperature. They have a simple design and are less expensive, but are also more difficult to read. Analog thermometers usually have a longer lifespan, which is something you should definitely keep in mind.
Digital Thermometers
These updated models pack a modern look and a screen to present with more information. Again, it is better to buy one of these with a larger screen, for convenience sake. They will blend into your home easily and can be read by anyone at any time. Most digital thermometers also offer a backlight, which is very convenient.
Weather Forecasting Thermometers
This type will give you plenty of in-depth information, aside from the temperature. They will show you such things as humidity and wind speed. We recommend these if you want to get a more accurate reading.
Clock Thermometers
Aside from temperature, this type will provide you with a time and date. They are particularly useful for any indoor environment.
Where to Place the Outdoor Sensor
For accurate temperature reading, you should place the sensor five feet above the ground. This will keep the ground temperature from interfering with your reading. Also, you should not keep it in a place that is directly exposed to sunlight or high precipitation, because that affects the readings. Thick walls or metals can also interfere with the signal, so be wary of that. Lastly, the area needs to have good airflow.
