You check your phone for the weather, then step outside and it feels ten degrees different. An indoor outdoor thermometer gives you the real temperature right at your own door, plus the temperature inside, all from one display. Some also show humidity and a forecast. Here are the 5 best indoor outdoor thermometers in 2026, ranked by star rating and how many people reviewed them.
We didn't personally test them. We compared the listings, the range claims and the review patterns. Wondering if a plain indoor thermometer can be used outside? See our answer on using an indoor thermometer outside.
What to Look For in an Indoor Outdoor Thermometer
Wireless range. Most claim 165 to 500 feet in open air. Walls, brick and metal cut that a lot, so treat it as a best case and pick a longer range if the sensor goes far from the display.
Humidity. A thermometer that also shows humidity is useful for a basement, a greenhouse, a garage or a baby's room. If you only want the temperature, skip it and save some money.
Extra sensors. Some models take up to three remote sensors, so you can watch a garage, a shed and the yard at once.
Display. Large digits and a backlight matter more than they sound. If you read it from across a room or in the dark, buy one with a bright screen.
Sensor placement. Put the outdoor sensor in the shade and out of direct sun, or it will read too high. A covered porch wall on the north side works well.
The 5 Best Indoor Outdoor Thermometers in 2026
1. TempPro TempAir 500FT Wireless Indoor Outdoor Thermometer with Sensor
Best for: people who want temperature and humidity with a long range.
A small display with a wireless outdoor sensor that shows temperature and humidity for both inside and out. It has 4.2 stars from more than 36,000 reviews, the most on this list. The listing claims a 500 foot range and support for up to three remote sensors.
What makes it stand out: It's the best seller by review count, and it shows 24-hour highs and lows and trend arrows. Getting humidity and a long range at this size is a strong value.
Good to know: The 500 foot number is an open-air claim. Through walls, expect much less. The plastic feels light, and the stars are a bit lower than the next two picks.
2. La Crosse Technology C85845 Wireless Weather Station
Best for: people who want a forecast and alerts, not just a number.
This one is a weather station with a color screen. It shows indoor and outdoor temperature and humidity, a forecast icon, dew point, heat index and a clock. It scores 4.4 stars from over 22,000 reviews.
What makes it stand out: The big, bright color display is easy to read from across the room. It also has customizable alerts and an adjustable brightness setting.
Good to know: It's bigger than the others, so it needs a shelf or desk. The extra features take time to set up, and it costs more than the plain thermometers here.
3. AcuRite 00424CA Digital Thermometer with Indoor and Outdoor Temperature
Best for: a simple, reliable setup with no humidity extras.
A basic display with a wireless outdoor sensor. It shows temperature trend arrows and daily high and low records. It has a 4.4-star rating from about 8,400 reviews. The seller lists a range of up to 165 feet.
What makes it stand out: It's easy to read and simple to set up, from a brand known for home weather gear. The display stands up or hangs on a wall.
Good to know: It doesn't show humidity. The range is shorter than the others, so it's best for a sensor on the same side of the house.
4. Taylor 1730 Wireless Indoor/Outdoor Thermometer with Remote Sensor and Clock
Best for: an easy-to-read display with a clock.
A compact black display with large digits for both temperatures plus a clock. The remote sensor sends readings up to 200 feet, according to the listing. It has 4.2 stars from nearly 11,000 reviews.
What makes it stand out: The big numbers are easy to read, and it's a no-fuss pick for a kitchen or desk. The clock is handy.
Good to know: It has no humidity reading. Check the listing for backlight details if you need to read it in a dark room.
5. VIVOSUN Indoor Outdoor Thermometer Wireless Digital Hygrometer with Touchscreen LCD
Best for: grow tents, greenhouses and anyone who wants a backlit screen.
A touchscreen display with a backlight that shows temperature and humidity inside and out. The listing says the sensor reaches 200 feet and the unit supports up to three sensors. It has 4.2 stars from over 6,400 reviews.
What makes it stand out: The backlight makes it readable at night, and the multi-sensor feature is useful for a grow tent or a garden. It comes with batteries.
Good to know: It has the fewest reviews of the five, so there's less feedback to go on. Touch controls are a matter of taste.
How to Get an Accurate Reading
- Mount the outdoor sensor in the shade, out of direct sun and away from walls that hold heat.
- Keep it at least a few feet off the ground and away from vents, dryers and grills.
- Put fresh batteries in both the display and the sensor. Cold weather drains batteries fast.
- Place the display within range, ideally not behind a thick wall or a big metal appliance.
- Let the readings settle for 15 to 30 minutes after setting it up before you trust them.

We'd pick the TempPro TempAir for most people. It has the most reviews and gives you humidity and range at a fair price. If you want a forecast and a bigger screen, spend more on the La Crosse.
The AcuRite is the simple one that just works. Get the VIVOSUN if you need a backlight or you're watching a grow tent, and the Taylor if you want a clock and large digits.
