Fog vs. Mist: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 23, 2023
Fog is a thick cloud of tiny water droplets near the ground, reducing visibility more than mist, which is lighter and less obscuring.

Key Differences

Fog is a dense accumulation of tiny water droplets suspended in the atmosphere close to the Earth's surface, often severely restricting visibility. Conversely, mist is a thinner collection of these droplets, causing only slight visibility reduction.

When driving in conditions with fog, it's common to use fog lights due to the significantly reduced visibility. In contrast, during mist, regular headlights are often sufficient since the droplets disperse light less intensively.

Areas prone to fog often experience it due to specific geographic, climatic, or environmental factors, such as coastal regions or valleys. On the other hand, mist is more commonly associated with mornings or times following light precipitation.

While both fog and mist are formed under conditions of high relative humidity, fog typically occurs when the difference between the temperature and dew point is less than 2.5°C (4.5°F). Mist, however, can form even when this difference is slightly larger.

People often describe fog as giving a mysterious or eerie ambiance to landscapes because of its denseness. Mist, being less dense, lends a more gentle and ethereal quality to surroundings.
