In this study we analyzed data from three meteorological stations situated in Romania's south part (Bucharest, Constanta and Craiova), in the period 1977-2016. There were calculated several primary climate parameters (annual average temperature; average temperature in the growing season; average temperature in summer; average maximum temperature in the warmest month; average minimum temperature in the coldest month; annual precipitations; precipitations in summer), and bioclimatic indices (Huglin Index, Winkler Index and Cool Night Index). It has also pursued the evolution in time (19 years), of Feteasca regala, the most common grapevine cultivar in Romania, in close connection with the evolution of climatic parameters. In the period studied, it was found a highly significant trend for average temperatures (annual, during the growing season, summer, and maximum) and Huglin and Winkler indices.The results show the role of the variability, from year to year, of the warmer temperature, which affects grape production and its quality. The increase trend of the grapes sugar content was found to be highly significant (r = 0.809***). Reducing titratable acidity of the must under 4 g/L, observed during the last decade, requires acidification measures.
