Runner Up

Ambient Weather WS 10 has a feature that no other thermometer on this list has! When you first take a peek at its display, the amount of information may seem confusing because it displays up to three outdoor readings at once.

Highlights

Many thermometers can sync with many devices, but none of them will display all three readings at once. WS-10 can sync up to eight devices but will display three at a time.

For some people, the above feature may be useless. But it is quite helpful for anyone who keeps barn animals or livestock to check up if they are doing all right or not.

Best Warranty

If you are on a tight budget, then Thermo Pro TP65A will be our top recommendation! Don’t be fooled by its affordable pricing, the readings are still accurate and reliable.

Highlights

The thermometer’s best feature is its backlit and huge 4″ LCD display. It is not only easy to read in a hurry but convenient too. It is also useful in checking humidity and temperature at night without actually turning on the lights. You will not have to unmount the tool, again and again, to be able to adjust the settings.

The large LCD screen also displays the time in a 24-hour format, and also sends out alerts in case of the all-time low and high records are touched for humidity and temperature. It also shows the current trends for each humidity and measurement icon, letting you know if the indoor is too cold, too humid, or too hot. This model by Thermo Pro can also be synced with two additional thermometers to check on different locations.

The cherry on top comes with the impressive warranty offered. The tool comes with a default one year warranty, but if you register the product on the website, then you can get an additional three-year warranty after purchase.

The display is colored with beautiful icons, and an adjustable backlight enables you to read it in dim light. The device features an atomic self-setting clock with automatic daylight savings time option.

This indoor outdoor thermometer has a range of 330 feet and can run either on batteries or a power cord. It requires 3 AAA alkaline batteries for back up or a 5 watt adapter for primary power. If you want to measure temperature below 20 ˚F or -28.8 ˚C, the outdoor sensors must be equipped with 2 AA batteries.

It displays the weather and humidity forecast, heat index, dew point, barometric readings, and temperature trend. It also records the minimum and maximum temperature and humidity values. There is also a reception and low battery indicator. The best part is that it is weather resistant to light moisture, however not waterproof. So, you better place it in a region that doesn’t soak it in heavy rain.

WHAT WE LIKED

  • Animated, colorful, landscape LCD display
  • Runs on a power cord and battery too
  • Reliable and accurate readings

WHAT WE DIDN’T LIKE

LCD Display: 8.34″ x 5.48″

Best Affordability

This tiny yet elegant indoor outdoor thermometer is the most affordable one on this list. It’s super simple, minimalistic, and provides accurate indoor and outdoor temperature readings.

Highlights

AcuRite 00782A2 offers multiple mounting options, giving it flexibility in placement. The sensor transmits readings every 60 seconds. Hence, the temperature reading is always up to date.

The small LCD display is a little bit too small and can make it difficult for people with weak eyesight to read. The temperature is displayed in Fahrenheit, so avoid it if you prefer Celsius readings, or you’ll get entangled in converting the temperature. At this price, it’s fair that the device doesn’t offer either humidity or barometric readings. Although, an alternative model is available that displays humidity too.

This model is a little short on the transmission range, which is only 100 feet. You shouldn’t opt for this model if you plan on placing the sensor far away from the device. However, with a strong signal penetration of 433 MHz, the 100 feet distance is not affected by any physical obstruction. Overall, it’s pretty decent for the minimal price it comes at.

WHAT WE LIKED

  • Multiple mounting options
  • Minimalistic and compact
  • Affordable
  • Wireless

WHAT WE DIDN’T LIKE

  • Small display
  • Only Fahrenheit readings
  • Low transmission range

Transmission Range: 330 ft.
Indoor Temperature Range: 32 ˚F to 122 ˚F (0 ˚C to 50 ˚C)
Outdoor Temperature Range:-40 ˚F to 140 ˚F (-40 ˚C to 60 ˚C)
Weight: 1.55 pounds
LCD Display: 7.75″ W x 6.2″ H

Best Premium

If you are willing to spend a little more, AcuRite 02081M Weather Station is the best premium indoor outdoor thermometer on the list.

Highlights

Its most striking feature is the full color, bold, and bright LCD screen display. The information is easy to understand with its big screen and 14 animated weather graphics. However, the viewing angle isn’t the best.

The device can work either on a power outlet or batteries too. It comes with an AC adapter. However, the batteries for the thermometer must be used only for backup since they drain pretty quickly. The outdoor sensor needs 2 AA alkaline or lithium batteries for power.

One of the best features is the 12 – 14 hour weather forecast that works by self-learning calibrating and by the data received from the outdoor weather sensor. This helps you plan your day well in advance. It claims to use barometric pressure to generate forecasts, but the barometric pressure reading is not displayed on the screen.

It also has tons of other features, including displaying the classic indoor-outdoor temperature display, date and time, calendar, temperature trends, and minimum and maximum temperature. The atomic clock automatically adjusts the time for any daylight savings and shows the time with ultra-high accuracy.

The temperature sensors are highly sensitive and give accurate readings. The sensor updates the data every 16 seconds, keeping it up to date. It is easy to mount, is weather-resistant, and has a 330 feet transmission range. The only drawback is that it does not display humidity.

WHAT WE LIKED

  • Attractive display
  • 12 – 14 hour weather forecast
  • Atomic clock with ultra-high accuracy
  • Accurate readings

WHAT WE DIDN’T LIKE

  • Expensive

The readings get updated every 50 seconds. It features a backlit touchscreen that keeps you updated on every slight change in the living conditions.

This indoor outdoor thermometer can be synchronized with 3 outdoor remote sensors, enabling you to track the environmental conditions in various locations throughout your home. Its smart design features multiple mounting options, providing you flexibility. It contains a rechargeable lithium battery to enable low-temperature monitoring.

Our Pick Again

This model of La Crosse is great for people who are looking at a digital indoor outdoor thermometer without the extra frills.

What to Look for in the Best Indoor Outdoor Thermometer

When in the market for indoor-outdoor thermometers, these are the following features to keep in mind:

Display

The thermometer’s display is the primary interface. To ensure no fuss handling, it needs to be of high quality. The larger the screen, the better it is. A small screen makes it difficult to read and can result in wrong readings. Bigger screens provide more clarity and are not cramped with information.

If your thermometer is advanced and displays loads of information at one instant, color coding can be handy. It not only makes your device look good, but it also gets easier to gather the necessary information. Backlit light is also a must-have feature since it ensures that you can read the numbers even in low light or complete darkness.

Brightness is something that buyers usually overlook when buying a thermometer. It becomes essential when you plan on installing the device outdoors or near a window where there’s vast exposure to sunlight. Also, the viewing angle must be such that it isn’t too difficult to make out the information from a distance. It is safe to say that the cheaper models do not offer optimum display. You’ll probably have to closer to get a better look for most of them.

Indoor and Outdoor Temperatures

It is rather obvious, but ensure that your thermometer’s temperature range is compatible with the temperatures your region experiences. If your region is prone to extreme temperatures, a limited temperature range might fail you.

Depending upon the country you are from, you might prefer one metric system over the other. Most of the thermometers allow you to choose the one you want from the settings. So, ensure to opt for the one that displays either, Celsius and Fahrenheit or the one that you prefer.

Wireless Indoor Outdoor Thermometer

Wireless indoor outdoor thermometers are battery operated. While the wireless thermometers are fuss-free and portable, the battery replacement might cost you a lot. Also, you’ll have to replace the batteries every now and then. However, if you opt for a wired one, the device will need a constant power supply, and you’ll have to place it near a power outlet. This choice is really a matter of personal preference.

Barometric Pressure

Also called atmospheric pressure, barometric pressure is the measure of pressure exerted by the weight of air in the Earth’s atmosphere. Even though the air is very light, the gravitational pull exerted on the molecules tends to create pressure, which has a significant impact on the human body. (1)

Barometric pressure is only available in advanced thermometers and can help forecast the climatic and weather conditions. One can determine whether it will be scorching heat or will the skies be covered by clouds.

Air pressure affects the weather by influencing the movement of air around the world. High air pressure indicates a lower air temperature, which generally promises blue skies. However, for low air pressure, the warm air rises in the atmosphere, leading to strong winds and promoting the formation of clouds, even precipitation.

In sunny places, the changes in air pressure are pretty rare. So, this feature is pretty much useless in such regions. However, in places with drastic seasonal changes, after some time, you’ll be able to locate the link between changes in weather conditions and air pressure.

Range

The models in our list vary from ranges between 100 – 330 feet. Although obstructions, such as solid walls and other wireless signals like cell phones and internet routers, can reduce the transmitters’ effective range. When setting up the thermometer, you must check various spots and pick the one that’s in the shade and has the strongest signal.

Weather Forecast

Weather and Temperature forecasts help you plan your day and week in advance, depending upon the thermometer you buy. Some thermometers forecast the weather for weeks, while some only for the upcoming 12 to 24 hours. So, pick the one that suits you.

This feature is handy if you travel a lot and need help sorting out the perfect sunny day for an outing. Some thermometers even alert you when the climate is hazardous. This ensures that you do not get stuck in a storm, hurricane, or heavy snowfall.

Time and Date

Most of the indoor-outdoor thermometers have a clock that displays both the time and date. This feature lets you check the time every time you walk past the device.

Accuracy

It is one of the key aspects of any measuring device. Accuracy depends largely on how far the remote sensor is placed. The father it is, the more the chances of error in the reading. Most sensors work perfectly up to a distance of 100 feet, which is sufficient for the majority of the users.

Anyhow, the readings fluctuate by 1-2 degrees, which might not be significant if you are using these thermometers to decide how to dress up. But, for technical usage, like the greenhouse, food storage, and pet care, the readings need to be accurate.

Other Features

Some other features like humidity, UV index, mounting options, and smart home integration can also be important. A few advanced devices provide alerts for extreme weather conditions like storms, hurricanes, or heavy snowfall. (2, 3)

Final Thoughts

You can pick any one of these thermometers up without hesitation as they all come with top of the line features, good reputation, and are some of the buyer’s favorites. Although, we are leaning more towards the La Crosse Technology C85845, because of it’s affordability, large and attractive display, and impressive range.

We hope we were able to narrow down some of the options for you and give a wide range of thermometers that are top-notch!
