This paper presents the results of climatological elaboration of pluvial and thermal conditions in Beskid Śląski Mts. The data comes from measurements from 1957 -2008 which collected at 25 meteorological stations and posts situated in Beskid Śląski region. The aim of this study was evaluation of the climate changeability on spruce stand stability in Beskid Śląski lower subalpine forest zone. The work includes studies on the adaptation possibility of spruce forest to present and future climate in Western Beskids. The study used historical data and a series of meteorological data generated using a model WGENK (Kuchar 2005) a range of 100 years. Calculation procedure based on two scenarios, the CO₂ concentration of 130% and 200% by 2050. Based on the results the productive potential of spruce stands in the forest subalpine zone was performed.
