Current climate change contributes to essential modification of crop development phases and quality [1]. At the same time, these conditions may weaken or conversely, increase the quality of the vine’s grapes. Taking into account the trends of climate change in the August month - time when the quality of the grapes is determined, it is extremely important to quantify the climate suitability degree for grapes quality [2, 3]. We note that this requirement is determined by the fact that in recent years, throughout the country, during August, there is an increase in the intensity of thermal maximum beyond the limits, significant variability of relative air humidity and diurnal thermal amplitudes is recorded.
