The occurrence of weather conditions unfavourable for agriculture in the Wieliczka Foothills, in the years 1988-2003 were examined. Changes in the number of days with minimum air temperature 2 m above ground level less or equal 0 deg C, 5 cm a.g.l. less or equal 0 deg and with maximum air temperature 2 m a.g.l. greater or equal 25 deg C in the vegetation periods proved the coninuation of warm climate fluctuations in this area. The number of days with daily precipitation greater or equal 0 mm (20.2 on average) and with thunder-storms (26.2) varied least in the analysed period (variability index 28 and 17.3 percent, respectively). Mean number of days with hail in the vegetation period was only 1.4. The number of days with extreme daily precipitation was the factor that mainly increased in the study period as compared with earlier data
