Abstract: The main purpose of the study is to analyze the variability of certain bioclimatic indicators (the Winter Scharlau Index, the Summer Scharlau index, the Relative Strain Index-RSI, the Wind Chill index) in order to identify the degree of comfort felt by tourists in the white dominant area on the northern side of the Parâng Mountains. The necessity for this study is apparent in the context of the development of mountain tourism and that of winter sports tourism in the Parâng mountain resort in particular. The relevance of the results is also due to the analysis of the climatic parameters (temperature, relative humidity, wind) at two different moments in time during the tourist seasons (winter and summer). The Parâng Mountains feature a large area that favors skiing, which accounted for the tourist refurbishment of the white dominant area in the northern sector as early as 1960-1970. The typical features of the natural landscape and tourist accommodation facilities created in the Parâng mountain resort justify the heavy inflow of tourists from numerous regions in Romania in wintertime..
