Fog data of Southern Germany from the period 1949–1990 indicate a significant urban influence on fog frequency. An increase of the urban building density is connected with a reduction in the average number of fog days, which is interpreted as an effect of the urban heat island and moisture deficit. Feedback mechanisms which intensify the urban‐rural contrast are discussed. The results are transferable to large cities with relatively good air quality. The study is a contribution to the controversial discussion about the urban effect on fog frequency.
