The analysis of the meteorological vegetation season from the period of 1971-2000 was recorded in the Beskid Sądecki Mountains, in the phytoclimatic research station at Kopciowa near Krynica. The station is located at the altitude of 720 m. Its geographical coordinates are φ = 49º27 N and λ = 20°58' E. This paper jointly presents the length of the vegetation season and dates of its beginning and end. In the years 1971-2000 the meteorological vegetation season began on average on 14 April and finished on 19 October. Its duration was 189 days. The shortest vegetation season was noted in 1997 and lasted 160 days. The longest one occurred in 1989 for 211 days. The duration and dates of the beginning and ending are characterised by a large annual changeability. Almost 25% of annual indicators differed from one another by two weeks. The earliest date of the beginning of the vegetation season fell on March 28, 1989; the latest was on May 1, 1980. The latest end date of a meteorological vegetation season was November 16, 2000. The earliest end date was September 30, 1997. The average multi-annual air temperature of the vegetation season was 10,5°C. The warmest vegetation season in of the period of 1997-2000 occurred in 1983, with an average air temperature of 11.7°C.
