Where you place an outdoor thermometer is critical for accuracy
Accuracy: The primary reason is to obtain the most accurate temperature readings. If the thermometer is placed near a heat source, in direct sunlight, or in a sheltered area, it may give false readings. The porch or under an eve in the shade is perfect.
Consistency: For consistent readings, the thermometer should be placed in a location that is representative of the overall outdoor environment, not an area that is significantly warmer or cooler.
Avoid Damage: The thermometer should be placed in a location where it will be protected from the elements, such as rain, snow, or extreme heat, which could damage the device and render it useless.
Ease of Reading: The thermometer should be placed in a location where it can be easily read without having to go out of your way.
Safety: It should be placed in a safe location where it won’t pose a risk of injury to people, pets, or wildlife.
