Tourism is a major sector of the global economy, and it is strongly influenced by climate. This study aims to assess the effect of climate on tourism conditions of the province of Khorasan Razavi using Tourism Climate Index (TCI). To achieve the main aim, several stages carried out. To calculate TCI, Average monthly of maximum and mean daily temperature, minimum relative humidity, average daily relative humidity, precipitation, total sunshine hours and wind speed were used. The model was implemented for 31 stations, with 19-year period (1987-2005) in the study area. Determining of monthly TCI in the study area was carried out applying interpolated five important parameters in the raster format and linear model using spatial analyst- raster calculator. In the annual scale, the results of research indicated that area is experiencing different situations. For example last two months of spring, and last month of summer, with the TCI >80, distinguish with high tourist potential. The monthly analysis of TCI under the different temporal conditions also showed that proper and optimum tourist sites will be changed according to different climatic conditions over the area. Although this study was conducted on a monthly scale, but based on the daily data, there is ability to find the best climatic times for tourists during a month.
