Listen to the crickets! Count the number of cricket chirps in fourteen seconds. Then add forty to that number. For example, if you count ten chirps in fourteen seconds, that means it’s about fifty degrees Fahrenheit.
Look for a flash of lightning. Listen for a clap of thunder. Count the seconds between them and divide by five. For example: Flash! (Lightning!) Boom! (Thunder!) Say you’ve counted ten seconds in between. Dividing ten by five tells you that the storm is about two miles away. Go inside!
Here’s a good poem that is usually true:
Red sky at night,
sailors delight.
Red sky in morning,
sailors take warning.
This means that if the sky is red at night, it’ll be mild weather. If the sky is red in the morning, it’ll probably rain.
