2. Thermometer Placement 

After finding the perfect thermometer, it is time to find the perfect place to put it in. The location of the thermometer should be selected carefully.

Incorrect placement of the thermometer gives inaccurate readings and also damages the device. To help with that, experts recommend placing the thermometers on the north-facing side of the house. The north-facing side of the house gets the least about of direct sunlight. 

Place the device in a well-ventilated place, or on a window which is not near a tree or a grill. The thermometer should not be attached to a place that receives direct rainfall or snow, which will affect the readings.

The ideal location for a window thermometer is at the top of a glass-door or window. Additionally, you should also avoid placing it on the windows of higher floors because radiation cooling may decrease the original temperature reading.

You can install multiple thermometers around your house to check the temperature, for example, you may install one at your patio door and one on your kitchen window. It will allow you to find out which room is the hottest at a certain time of the day.

There are also thermometers that can send information from outside to an indoor monitor. There’s thermometers are called indoor/outdoor thermometers.

3. Thermometer Installment 

The mounting style of the thermometers may vary depending on their model. The thermometers may stick to the windows through electrostatic clings, suction cups, brackets, or adhesives. 

The stick-on feature allows easy cleaning of the window and the device. It is a simple 3 step process of peeling the thermometer from the window, cleaning it, and pasting it back.

Certain things would be helpful to remember before sticking the thermometer on the window.

For starters, you really need to clean the window before starting any process. Dirty windows may cause the adhesive to not stick properly. 

You need to make sure to remove all the air bubbles from the surface of the window when dealing with electrostatic clings. You can do this by going over the plastic covering with a ruler or a card and smoothing out the air bubbles.

Suction cups need moisture to stick to the glass surface so make sure to apply moisture to the surface to use the suction cups properly. This last bit of advice might seem silly, but don’t forget to take off the plastic covering from the adhesives before trying to stick them on. 

The device packaging contains an installation guide with clear instructions. For maintenance, you might need to charge the device, or find the appropriate batteries for it, at most. You should charge the device as instructed on the guide.

There are various installation video guides available online, which are almost the same for all models. So, you can check those video guides if the process is still unclear.


And there you have it. Your very own window thermometer is all set-up and ready to use.

You should make sure that you have selected the right device for your preferences. Don’t let the large variety of window thermometers available online overwhelm you! Take your time. For extra guidance, refer to our buying guide to make the decision easier for you.
