Quick answer
- For indoor and outdoor temperature plus a forecast, look at a wireless weather station such as the AcuRite 75077A3M or the Tohsssik color weather station.
- For long wireless range to an outdoor sensor, the ThermoPro TP63B lists up to 500 feet (150 m).
- For simple indoor humidity monitoring in more than one room, the ThermoPro TP50 comes as a two-pack.
- Buy only the features you will actually use: extra sensors and forecasts add cost.
An indoor outdoor thermometer shows the temperature inside your home and outside it at a glance, usually with a wireless outdoor sensor. Many models also show humidity, and the more advanced ones work as small weather stations with forecasts.
Below are four indoor and outdoor thermometers and hygrometers, based on manufacturer information and the features listed at the time of writing. For a closer look at one popular brand, see our AcuRite indoor outdoor thermometer article.
What to look for
- Outdoor sensor range: make sure the wireless range comfortably covers the distance between where you mount the sensor and the display.
- Number of sensors: some displays can show several locations, but may include only one outdoor sensor; extra sensors are sold separately.
- Humidity: a hygrometer helps you keep an eye on indoor comfort.
- High and low records: useful for seeing overnight lows or daily highs.
- Forecasting and display: weather stations add forecast icons and larger, often color, displays.
- Power: check what batteries are needed and whether they are included.

FAQ
Do indoor outdoor thermometers measure humidity?
Many do. In this list, the ThermoPro TP50 and ThermoPro TP63B both list humidity readings.
Can I monitor more than one outdoor location?
Some models support it. The Tohsssik weather station can show up to four locations, but it includes only one outdoor sensor, so extra sensors are needed.
