Global average cloud cover:
On average, about 60% of the Earth's surface is covered by clouds at any given time. This number can vary significantly depending on factors like location, time of day, and season.

Cloud cover is monitored by satellites and weather stations worldwide. This data helps meteorologists forecast weather and study climate patterns.
It's important to remember that cloud cover is dynamic and changes frequently, so it's impossible to give a precise answer to your question. However, the concept of cloud cover provides a valuable way to describe and measure cloudiness in the sky.
