Overcast vs. Cloudy: What's the Difference?
Edited by Aimie Carlson || By Janet White || Updated on September 26, 2023
"Overcast" describes the sky when it's completely covered by clouds, indicating heavier cloud density than "cloudy," which signifies any cloud cover, usually allowing some blue sky or sun to appear.
Key Differences
"Overcast" and "Cloudy" are meteorological terms used to describe the presence and amount of clouds in the sky. "Overcast" is more specific, referring to when the sky is completely covered by clouds without any breaks, often associated with more uniform and extensive cloud layers. In contrast, "cloudy" is a broader term, signifying the presence of clouds, which may cover a small or large portion of the sky, allowing for breaks and some visibility of blue sky or sunlight.
In meteorological observations, "overcast" is noted when cloud cover is so dense and extensive that it obscures the sun or sky entirely. The sky usually appears gray, and the condition might be associated with precipitation. "Cloudy," conversely, refers to varying degrees of cloud cover and does not necessarily imply complete coverage. The sun or other parts of the sky might still be visible, and the weather may remain dry, depending on other atmospheric conditions.
The implication of the terms "overcast" and "cloudy" also differs regarding light and visibility. An overcast sky typically results in diffused light, reducing shadows and contrasts, making it a preferred condition for photographers seeking even light. However, a cloudy sky may allow more light to penetrate, creating a mixture of light and shadow, depending on the thickness and type of clouds present.
The terms "overcast" and "cloudy" help in weather forecasting, providing insight into possible weather developments. Overcast conditions often precede rain, snow, or other forms of precipitation, and they may indicate an approaching weather front. On the other hand, a cloudy sky might not lead to precipitation and can be transient, with clouds coming and going, allowing intervals of sunshine.
Both "overcast" and "cloudy" conditions have varied impacts on temperature. Overcast skies can lead to cooler daytime temperatures due to the blockage of sunlight but may result in warmer nights as clouds trap terrestrial radiation. Cloudy conditions might see a more significant variation in temperature, depending on the amount and type of cloud cover, allowing more solar radiation during the day and more cooling at night when there are breaks in the clouds.
