How do you record how cloudy it is?

Answer 1

using cloud symbols:

An empty white circle = clear day

A black circle = overcast

a 3/4 white, 1/4 black circle = scattered clouds

a 1/2 white, 1/2 black circle = partly cloudy

a 1/4 white, 3/4 black circle = mostly cloudy

Answer 2

Cloudiness is typically measured using a scale called the Okta scale, which ranges from 0 to 8 based on the amount of sky covered by clouds. Observers visually estimate the percentage of sky covered by clouds and assign it a corresponding Okta value. Another method is to use instruments like a ceilometer or a pyranometer to measure cloud cover and intensity.
