The study aims at presenting extreme long-period, annual and diurnal cloud amount values in Kraków on the basis of 90-year records. Cloud data were taken from climatological observations made at Department of Climatology, Institute of Geography, Jagiellonian University in Kraków, in the years 1906-1995. For the biggest cloud amount the highest annual average was 78% and occurred in the years [94] and 1952, with St clouds dominating in the cloud structure. The highest monthly average was in December (81%), with As and St clouds dominating. An absolute maximum (98%) occurred in December 1959. The highest diurnal average was at noon, when convective Cu clouds were developing . For the smallest cloud amount the lowest annual average was 56% and occurred in 1982. The highest number of cloudless days (27) was observed in 1990 and the largest numbers of cases of cloudless sky were observed during the last 10 years, most often in September, particularly in 1992 The lowest monthly mean was in August (59%), but the absolute minimum (32%) occurred in March 1921. Cloudless sky was observed most often in October in the evening, the highest number of such observations (16) occurred in the year 1990. Cloudiness conditions in Krakow depend mainly on macroscale circulation processes and are modified by the loval influences only to a little extent. The changes of cloudiness show the same character of tendency and values as those in Central Europe.
