*Weather Conditions*

The weather data were collected from the meteorological station located in the Mountainous Experimental Station in Czyrna near Krynica Górska. The average precipitation in January, April, July, and August for the years 2011–2019 was similar for the multi-year (1962–1990) period. On average, the precipitation in May 2011–2019 was ca. 17 mm more, and in June 2011–2019 was ca. 24 mm less, than for the multi-year period (Table 2).

The average temperature for the vegetative period (April–August) of the 2011–2019 years was 2.4 ◦C higher as compared with a similar period of a multi-year (Table 3). On average, April and August of the 2011–2019 years were particularly warmer than for a multi-year, by 2.8 and 3.4 ◦C, respectively. Moreover, the average temperatures in January and May–July of 2011–2019 were ca. 2 ◦C higher from those of the multi-year period (Table 3).
