Studies on fogs report a great diversity of physical processes involved besides a strong dependence of the place of formation. The different possibilities of the advective, radiative and mixed patterns, associated or not to precipitation, make difficult the exact characterization of its life cycle and, consequently, its predictability. However, the advancement of satellite image visualization techniques as well as the increase in the database available free of charge at the national (CPTEC / INPE) and international (NOAA) levels, have improved the detection of this phenomenon after being formed. This work begins a quantification of the occurrence of fogs in the vicinity of Guanabara Bay through data obtained at the Santos Dummond (SBRJ) and Antonio Carlos Jobim - Galeão International Airports (SBGL), located in the city of Rio de Janeiro, evaluating its thicknesses and its relations with the astronomical tides. In addition, a case study was chosen to subsidize early investigations, and relationships with phenomena of synoptic scale.
