Binding to peripheral areas used for leisure. In this study, five indexes have been used to study Tabriz comfort climate. These indexes include: PMV, PET, SET, ET, and stress index. To determine the relationship between climatic factors and the number of tourists, the correlation coefficient is used. For calculation the above parameters the following variables are used) temperature, rate of moisture, wind speed, vapor pressure and rate of sky cloudy since 1970 to 2012(and personal variables (include: weight, height, age and sexuality) Also third group variables such as, cover type and rate of activity, longitude and latitude and number of tourists entering to Tabriz since 1382 to 1390. To analyze these variables, RAY MAN and excel software have been used. Above indexes showed that TIR and MORDAD month are the comfort for tourists and KHORDAD and SHAHRIVAR are semi-comfort. Stress index is not suitable for this study. The number of tourists also correlated with temperature and relative humidity is inversely related to the level of 1/0 is significant.
