The entire range of Czantoria * and Stożek * described here is characterized by a mountain climate. However, due to this, that the Silesian Beskids lie in the area where the influence of the oceanic and continental climate clash, Climatic conditions are highly variable throughout the year, and the weather often changes many times a day.
For approx. 2/3 of the year, moist polar-sea air from the north flows over the Silesian Beskids. Atlantic. In winter, it warms up to the full thaw, and brings increased cloud cover and rainfall. In summer, it flows in as cool air and is usually very cloudy, with heavy rainfall and a tendency to thunderstorms.. Polar continental air flows most frequently in October, March and January. In summer, it brings a wave of warmth, in autumn - sunny and rainless weather, and in winter - severe frosts. In autumn and winter, significant temperature inversions occur in this air masses.
West winds prevail in this area. i pn.-zach., related to the polar-sea circulation. In the valleys, however, the topography has a decisive influence on the direction of the wind: in the meridional running valleys of the Vistula * and Olza *, winds blowing from the northern directions prevail. i pd., while e.g.. in the Istebna basin * the east winds have a significant share. i zach. One should also mention the fen winds occurring in the Silesian Beskids - warm and violent descending winds, blowing from the south., known in the Tatras as mountain winds. They most often occur in the winter half-year, causing a lot of damage to tree stands and a sharp increase in temperature and melting snow cover.
The average annual sunshine duration in the Beskid Śląski region ranges from approx. 1350 (Vistula*) do 1550 (Istebna*) hours a year, i.e.. medium 3,7-4,2 hours a day, and in summer it is up to 5,8 while in winter it drops to approx. 1,5 hours a day. The villages in the valleys show the lowest sunshine duration, while the highest - places on the slopes to the south. exhibition. For example. pd. Kubalonka slopes * show annually 43 days with sunshine over 10 hours! The most cloudy period is from November to January, and the smallest - at the end of summer and the beginning of autumn (August – October). The highest number of foggy days was also found in November and December, especially common in the valleys.
The Silesian Beskid is one of the rainiest regions of Poland. Annual total precipitation, mainly associated with the influx of moist ocean air, depends on the elevation of the area above sea level and its exposure to rain-bearing winds, however, in the described area it does not fall anywhere below 750 mm. The slopes facing the west receive the most rainfall. i pn.-zach., the amount of rainfall increases with altitude. And so, for example. in the Vistula * (430 m) annual rainfall is 1190 mm, and in Wisła Malinka, on the west. the slopes of Malinowska Skała (690 m) until approx. 1400 mm. Istebna * and Jaworzynka * have less rainfall. Most rainfall occurs from May to August. They often take the form of heavy rains and violent storms. The least rainfall is recorded in September and October. The number of days of the year with rainfall varies from approx. 150 in the valleys up to approx. 200 in the higher levels.
Much of the precipitation falls on snow, the share increases with increasing altitude above sea level. The number of days with snowfall varies from approx. 30 u pn. at the foot of the mountains to approx. 90 in the top parts of the band. The first snow falls in the highest parts of the range, often already in October, permanent snow cover is formed in the mountains over a month later, and in the valleys only in mid-December. Snow keeps from 74 days in the Cieszyn area, 96 days in the Vistula * i 106 days in Istebna * up to approx. 130 days in the peak games of Czantoria * and Stożek *, where the conditions conducive to skiing usually last from mid-December to the end of March. The longest, because even until the end of April there may be snow on the slopes of the North., in deep, shady valleys and forested sections of ridges. In the valleys the thickest snow cover occurs at the turn of January and February, amounting to approx. 80 cm in the Vistula * and 98 cm in Istebna *. In the sub-peak parts, the snow cover may be up to 200 cm, on the exposed sections of the ridges, snow may sometimes be blown to the ground.
Lower parts of the discussed band, lying below 670 m npm, they belong to a moderately warm climate with average annual temperatures from +6 do +8°C. The areas located above this border lie on a moderately cool storey with temperatures ranging from +4 do +6°C. The average annual temperatures for towns located in the valleys are: Ustroń * + 7.1 ° C, Vistula * + 6.3 ° C, Istebna * + 5.7 ° C. The highest average monthly temperatures in this area occur in July: +16,3° C in the Vistula *, +15° C in Kubalonka * and + 14 ° C in the highest parts of the mountains. The coldest month is January with average temperatures from -3.5 ° C in the Vistula * to -5.8 ° C in Istebna * Zaolzie.
Just like in other parts of the Beskids, in the Silesian Beskids the temperature drops with altitude - depending on the season - from 0,5 up to 1 ° C each 100 m elevation. Therefore, at heights above 750-800 m above sea level, the summer climate disappears altogether, i.e.. period when average daily temperatures are higher than + 15 ° C. They are also common, especially in late autumn and winter, reverse situations, when it is cold and foggy in the valleys, and the sun is shining on the surrounding peaks and the temperature is a few or a dozen degrees higher. They are the so-called. temperature inversions, associated with stagnation of cold air in deep ground depressions. The largest such inversion in the Polish Carpathians in the current century took place in February 1929 r. In Istebna * Zaolzie the temperature was then -36 ° C.
As can be seen from the above, The Beskid weather likes to play tricks. This should not be forgotten and at all, even for a short trip you will need warmer clothes and raincoats. At the same time, in Ustroń * or the Vistula * one should not be afraid of the autumn fog, but try to look for the sun on the surrounding peaks.
