Where does advection fog typically form?

Advection fog typically forms in coastal areas due to the movement of warm, moist air over cooler sea surfaces. When warm air comes into contact with the cold water, it cools down and causes the moisture in the air to condense into fog. This type of fog is often seen along coastlines, particularly when there are steady winds that facilitate the movement of air. The temperature difference between the warm, moist air over the water and the cooler water is key to the formation of advection fog, making coastal areas particularly susceptible to this phenomenon.
