Overcast vs Cloudy: What’s the Difference?
Overcast and cloudy both describe skies with clouds, but they do not mean exactly the same thing. The main difference is the amount of sky covered by clouds.
A cloudy sky has many clouds, but some clear areas may still be visible.
An overcast sky is completely covered by clouds, leaving little or no visible blue sky.
The simple difference:
Cloudy = many clouds with possible clear areas.
Overcast = the entire sky is covered by clouds.
For example:
- The weather is cloudy, but I can still see patches of blue sky.
- The weather is overcast, and the sky looks completely gray.
Quick Answer
Cloudy means the sky has a large amount of cloud cover, while overcast means clouds cover the entire sky. All overcast skies are cloudy, but not all cloudy skies are overcast. Meteorologists often use “overcast” when cloud coverage reaches 100%.
