What are the best indoor/outdoor thermometers?

Mark Twain famously said, “Everyone talks about the weather, but nobody does anything about it.” Forecasters on TV tell you the weather, but only on their schedule and not when you need it. Online weather tells you what’s going on outside, but only in your general area.

An indoor/outdoor thermometer tells you the exact temperature and humidity inside and outside your home. Full-featured weather stations give you data on wind direction, precipitation and more.

What to know before you buy an indoor/outdoor thermometer

What is an indoor/outdoor thermometer?

An indoor/outdoor thermometer is one with an outdoor sensor and an indoor display with its own sensor. The sensors measure ambient temperature, humidity and more. 

What is a weather station?

weather station is an indoor/outdoor thermometer that provides you with much more weather information than just the temperature and humidity. People really interested in the weather prefer more complete devices that can measure the wind speed and direction, forecast the weather and alert you when bad weather is on the way. It is a common practice of sellers of weather stations to list them as indoor/outdoor thermometers.

Base station display screen

Indoor/outdoor thermometers feature two types of display screens, LCD and LED, and there are pros and cons to each.

  • LCD screen: They are less expensive and use less power, but have a narrower viewing angle and are often only monochrome.
  • LED screen: They offer long life, high efficiency and no heat. But they are more costly.

Where to place your outdoor sensor

Most manufacturers advise you to consider several things when choosing a place to mount sensors.

  • Direction: The north side of your home is the best place for most sensors.
  • Height: Your sensor needs to be at least 4 feet above the ground to prevent thermal radiation from giving you false readings. It also needs to be at least 1 foot below any overhang to prevent trapped heat from giving you inaccurate temperatures.
  • Sun: Avoid direct sun in favor of indirect sun or mild shade, because thermometers in direct sunlight deliver inaccurate temperatures. 
  • Ventilation: Accuracy improves when your sensor is in an area where the air moves about freely without restrictions or swirling.
  • Windows, doors and vents: Never put a sensor above any of these. Heat or cold escaping from your home will give you false temperature readings.
  • Rain: Keep your sensor out of the rain but open to the air. The exception is sensors with rain gauges that need their collectors to be placed out in the open, at least 10 feet from walls and trees, and where the wind does not swirl. 
  • Eaves: For most purposes, a great place for your outdoor sensor is 1 foot below the eaves on the north side of your house.
