What to Consider When Choosing the Best Outdoor Thermometer
These days, outdoor thermometers are available in a wide range of options, from simple analog varieties that only display the temperature to digital models with multiple weather-related features. The following are some of the most important considerations when searching for the best outdoor thermometer for your needs.
Type
While there are two main types of outdoor thermometers, analog and digital, thermometers can fall into several categories. Some of the designs and displays may work better for you.
Analog thermometers include two types: the retro type and the bimetallic strip.
- The retro is the classic garden thermometer, which is a vertical glass tube filled with thermosensitive liquid.
- The bimetallic strip or round dial type has a metal needle that points to the temperature marked on a circular scale.
Digital or electronic thermometers provide more precise and accurate readings. Their displays are usually easier to read, and many offer additional weather information. While all digital thermometers need to be placed out of direct sunlight and need protection from the elements, one can choose either a direct reading or a remote reading digital outdoor thermometer.
- Direct reading outdoor thermometers measure and display the temperature on the thermometer. For accurate temperature readings, they need to be between 4 and 6 feet off the ground in a spot with adequate airflow. Locating them under the eave of the house or on a covered porch is ideal.
- Remote reading outdoor thermometers transmit data wirelessly from an outdoor sensor to a remote indoor display unit that may be several hundred feet away. In addition to temperature, many systems have multiple sensors for measuring barometric pressure, ozone levels, the UV index, wind speed and direction, and rainfall. Some have large backlit displays that double as clocks, and may include features such as a 7-day weather forecast or memory function to record minimum and maximum temperatures over a designated period. Advanced models operate via a smartphone app that can deliver notifications. On the downside, they depend on a stable wireless connection, and obstacles can interfere with transmission of data.
Display
A display’s value comes down to readability. The measurement marks on an analog thermometer can sometimes be difficult to read. Digital displays often offer better lighting and take the guesswork out of determining the temperature. For improved readability at night, some of these displays offer backlighting with white numerals on a dark background.
Size also makes a difference. Analog displays need to be bigger to be readable from a distance, but even small digital thermometers can be easy to read.
Transmission Range
For remote reading digital thermometers, the transmission range refers to the distance a signal travels from the sensor to the display unit or hub. The indoor display needs to be within range of the sensor. Some have a range of only a few feet, while others offer a range of 200 to 1,000 feet. Models with a longer transmission range let users track the temperature in locations farther away from the house.

Some remote reading models are multi-zoned with two or three sensors to monitor conditions in different outdoor locations or indoors in rooms like a basement or attic.
Temperature Units
Most thermometers offer Celsius and Fahrenheit settings, though some may only have one or the other. Analog models often have side-by-side Celsius and Fahrenheit temperature units, while digital models let users switch between the two.
Functionality
At its most basic, the best outdoor thermometer provides an accurate reading of outdoor temperatures; however, many of today’s models offer much more. Some include several sensors that measure both temperature and humidity along with memory features that enable users to track patterns in the environment around a home. Many digital models also display the time and date, and some offer alerts and audible alarms if the temperature or humidity falls out of a preset range.
Programming and Calibration
Although most models do not need to be calibrated, some thermometers may require calibration when they’re first set up and periodically thereafter to make sure their readings are accurate. Follow the instructions in the owner’s manual for how and when to calibrate a thermometer.
If there aren’t any calibration instructions, try using one of two methods. The “ice-point method” is the quickest and most accurate. Fill a glass with ice and tap water, let it sit for 3 to 5 minutes, then insert the thermometer’s probe into the water. It should reach 32 degrees Fahrenheit and 0 degrees Celsius.
The “boil-point method” is another option; however, there’s a risk of scalding, and the boiling point is affected by elevation, which can throw off the calibration. Bring a pot of water to boil and insert the thermometer’s probe. It should match the known boiling point, which at sea level is 212 degrees Fahrenheit or 100 degrees Celsius.
Some thermometers let the user calibrate the readings for accuracy, while others don’t. With those that don’t, it’s important to know how far off the readings are and mentally adjust the temperature based on the thermometer’s setting.
Models with front-facing controls are easier to program because any adjustments can be made while the thermometer is mounted or on a tabletop.
Battery Life
Check what kind and how many batteries the thermometer needs. Digital models with multi-zone sensors usually need the most batteries because often both the display and sensors use them. It’s best if the devices have a long battery life. Many thermometers are small and efficient enough to only need replacement batteries every few months to a year. However, weather conditions and how the thermometer is used can affect the battery life.
Some models connect to an electrical power source and only use batteries for backup. Simple analog garden thermometers don’t require batteries because they rely on the laws of physics to measure temperature.
Smart-Home Integration
Digital weather stations often have a smart-home integration capability. As long as they run on the same Wi-Fi network as other devices, these thermometers can connect to a digital assistant like Google Assistant or Amazon Alexa. From there, users can use voice control to monitor the environment in and around a home.

We also tested the Netatmo Weather Station, but it was difficult to set up. The system gets lots of points for its beautiful design, and we hoped the functionality would measure up to the design, but unfortunately the installation was so difficult that we couldn’t recommend it.
To begin installation, an app needs to be downloaded and then registered before the setup process can begin. We scanned the QR code on a card included in the package that was supposed to take us directly to an Apple HomeKit app for iOS phones or to the Google Play store for the Android app. The QR code worked for the Android but never worked for the iPhone. Ultimately, after several tries and workarounds, we were able to connect on the iPhone, but since the unit had been pre-registered on the Android, that user needed to invite the “additional” iPhone user to join the household.
Once we were able to access the app, it was pretty simple to use and offered loads of features, including an interactive map for viewing the weather anywhere in the world. The system senses and displays temperature and other data, including humidity, barometric pressure, CO2, and ambient sound (it was correct when it showed it was quiet, but we already knew that).
Our Verdict
From our tests, the La Crosse Technology Digital Weather Station stood above the rest as the best overall outdoor thermometer and weather station. Although there were others with many more features and bells and whistles, this one offered the best combination of good transmission range, simple setup, and an easy-to-read display to make it our top pick.
For those looking for an outdoor thermometer packed with features, it’s hard to beat our upgrade pick. The WeatherFlow Tempest Weather System has a long 1,000-foot transmission range and remote management via a smart app.
How We Tested the Best Outdoor Thermometers
To ensure equal testing conditions and to test the wireless connectivity, we installed six outdoor thermometers about 1 foot apart on a covered porch. This location was approximately 30 feet away from the indoor room where we placed the hubs. Additionally, we tested the wireless connectivity of the devices from an open area of a backyard about 70 feet from the house.
We tested the thermometers in New Orleans, Louisiana, from mid-March through mid-April, when the area was experiencing weather and temperature fluctuations from low 60s to high 80s with varying amounts of humidity.
We periodically checked the temperatures at different times of the day to compare readings between the products. We also compared the indoor temperature data to the temperature displayed on the home thermostat. The stations reported readings within a few degrees that corresponded closely to the home thermostat’s reading.
For devices offering a forecasting function, we compared their information to the National Weather Service forecasts and found each reported similar data. For stations displaying the historical minimum and maximum weather (beginning from the installation date), we noted that their reported temperatures were also within a few degrees of each other and the national weather reports.
FAQs
Tracking temperatures lets you plan your outdoor activities, take better care of a garden and yard, and dress for the weather. However, there are a few tricks to their use and setup, so there may be a few lingering questions. Below are answers to some of the most popular questions about outdoor thermometers for the home.
Q. How do I know that my outdoor thermometer is accurate?
Perform an ice-point or boiling-point test. The ice-point test involves putting the sensor or probe in a cup of ice water. It should display 32 degrees Fahrenheit or 0 degrees Celsius. The boiling-point test works the same way. Boil a pot of water and place the thermometer’s probe in the water. Then, compare the readings to the known boiling point of your altitude. Keep in mind that altitude and air pressure can alter the freezing and boiling points.
Q. Can you adjust an outdoor thermometer?
Outdoor thermometers can usually be calibrated to make sure they’re providing accurate readings. With some, you may simply adjust the dial to match the results of an ice-point or boil-point test. Digital models may offer a way to adjust the readings according to an ice-point test, or they may have a reset button that calibrates the thermometer back to digital settings.
Q. What is the best place to put my outdoor thermometer?
Try to place the thermometer somewhere where the readings won’t be altered by landscaping, the sun, or the weather. For example, it should be between 4 and 6 feet off the ground and at least 20 feet from concrete. Concrete reflects heat, causing the temperature to rise.
Outdoor thermometers and sensors don’t belong in full sun. Direct sunlight can cause higher temperature readings that don’t match the actual air temperature. Finally, try to place the thermometer where it has a degree of protection from rain.
