Can crickets reveal the temperature?

Spring means that we will soon hear the chirping of crickets once again, but could you use their chirps to work out the temperature?

Yes, as strange as it sounds there is a way of using the frequency of the chirps to calculate how warm it is in your area.

The relationship was first discovered by Margarette W. Brooks in 1881 but is known as the Dolbear’s Law after Amos Dolbear who published the findings in 1897.

It is a simple measure to carry out. Simply count the number of chirps in 25 seconds, divide that number by three and add four to find the temperature in Celsius. To convert the Fahrenheit, simply calculate the following: Fahrenheit = (Answer in Celsius x 1.8) + 32.

This does not work as accurately with field crickets as their chirping is influenced by other factors but will still provide a rough temperature. So, as the crickets begin to reappear and their chirps once again flow through the air try this trick yourself.
