Crickets can’t make a forecast, but they can tell you if it’s warmer or colder.
But even more impressive than that, is they can act as a natural thermometer and tell you the current temperature!
Crickets make more noise in warm weather – simply because it’s easier for them to chirp. The noise a cricket makes is from rubbing its wings together. In colder weather, this is harder for crickets to do, so in warm weather there’s more chirping.
The number of chirps a cricket makes relates to the temperature.
This was discovered in the late 1800s by Amos Dolbear. He found that counting the number of chirps a cricket makes over a certain time gives the air temperature outside within a few degrees.
This relation is called Dolbear’s Law.
So if you want to find out the air temperature outside with a cricket, it’s fairly simple.
Just count the number of chirps a single cricket makes in 15 seconds then add 40.
