Here’s the view from our tent flap last weekend. Notice the little girl and puppy footprints from a weekend filled with digging in the sand, playing in the water, and enjoying a campfire. One last weekend sleeping under the stars before the weather cools.
Today, dear hearts, let’s dabble in Dolbear’s Law.
Oh, no—don’t run off!
Dolbear’s Law is neither as lofty nor as boring as you might think (c’mon, now, you know me better than that).
Forget gavels, girls, and take the hint:
Mind you, the clue is not so much “Jiminy” as “cricket.”
That’s right—Dolbear’s Law concerns crickets. More specifically, it reveals the relationship between air temperature and the rate at which crickets chirp.
It’s true. When crickets are singing in the evenings from spring through fall, you can actually figure out the temperature outdoors by counting chirps. Here’s how, according to The Old Farmers Almanac:
Count the number of chirps in 14 seconds, and then add 40 to find the temperature in Fahrenheit.
For example: 30 chirps + 40 = 70°F
It works for Celsius, too, in case you were wondering. Metric mavens can count the number of chirps in 25 seconds, divide by 3, then add 4.
The cricket sound clip below plays for only a few seconds, but you can play with it to get an approximation:
And, as if THAT cricket fact isn’t mind-tickling enough, there is a rumor floating about that says a slowed recording of cricket chirps sounds like a human chorus. Listen:
