San Francisco is the poster child of advection fog. It is common anywhere you have a cold ocean current with frequent incursions of warm, moist air.
Radiation fog forms when the ground loses heat at night, cooling the air above it to its dew point. Advection fog, on the other hand, forms when warm, moist air moves over a cool surface and cools to its dew point. Both fogs are common in valleys and coastal areas, but radiation fog is more localized and forms on calm, clear nights, while advection fog can cover large areas and is often associated with wind.
There are two types of fog, advection fog and radiation, or ground fog. Advection fog is common along the pacific coast of the United States. Warm, moist air over the Pacific Ocean is blown inward. The other kind of fog is radiation, or ground fog. This fog is common lots of places. It forms when a layer of warm, moist air forms low to the ground.
The two main types of fog are advection fog, which forms when warm, moist air moves over a cool surface, and radiation fog, which forms when the Earth's surface cools down rapidly by radiating its heat into the atmosphere.
Advection fog may result when warm moist air moves over a cold surface. This type of fog forms when the moist air cools down to its dew point temperature, causing water vapor to condense into tiny water droplets that remain suspended in the air.

Freezing fog, advection fog, and evaporation fog!
advection fog
Advection fog forms when moist air moves horizontally over a colder surface, causing the air to cool and reach its dew point, leading to the condensation of water vapor into fog.
Radiation fog forms when the ground loses heat at night, cooling the air above it to its dew point. Advection fog, on the other hand, forms when warm, moist air moves over a cool surface and cools to its dew point. Both fogs are common in valleys and coastal areas, but radiation fog is more localized and forms on calm, clear nights, while advection fog can cover large areas and is often associated with wind.

The four types of fog are radiation fog, advection fog, upslope fog, and evaporation fog. Radiation fog forms on cool, clear nights when the ground loses heat rapidly. Advection fog occurs when warm, moist air moves over a cold surface. Upslope fog is formed when moist air is forced to rise up a slope or mountain. Evaporation fog occurs when air near the surface is cooled to its dew point by evaporation.
Radiation fog forms when the ground loses heat through radiation at night, cooling the air near the surface to its dew point. Advection fog forms when warm, moist air moves horizontally over a cooler surface and cools to its dew point, resulting in fog. The main difference is the mechanism by which each type of fog forms.
Advection fog along California's coast is primarily caused by the interaction of warm, moist air moving over cooler ocean waters, leading to condensation. Additionally, the presence of coastal upwelling, which brings colder water to the surface, enhances this cooling effect, further promoting fog formation. Together, these conditions create the ideal environment for advection fog to develop, particularly during the spring and summer months.
Favorable conditions for the development and maintenance of both radiation and advection fog include high humidity, light winds, and temperatures near the dew point. Radiation fog typically forms on clear nights when the ground cools rapidly, allowing moisture in the air to condense. In contrast, advection fog occurs when warm, moist air moves over cooler surfaces, causing the air to cool and condense. Both types of fog thrive in stable atmospheric conditions where vertical mixing is minimal.
Advection fog results when moist air moved across a cold surface. When moving across a cold surface, the air is cooled to its dew point.
