Abstract: Climate is consisted of temperature, air relative humidity, wind speed, sunshine, precipitation and other factors, and the interaction among the factors affects the natural ecosystems and human activities. Studying the regional tourism climate could not only provide the meteorological evidences for the tourism development, but could also help the tourism operators to choose the appropriate activities, time and places for tourists. According to the meteorological data in Urumqi during the period from 1962 to 2011, in this paper the main tourism climatic factors, such as the air temperature, relative humidity, precipitation, wind speed and sunshine duration, were analyzed. Based on calculating and analyzing the hydrothermal index, windchill index and clothing index, a new integrated comfort index model was developed to analyze the integrated comfort degree of tourism climate in Urumqi, and the grades of tourist fitness and time distribution are divided. The results are as follows: ① The traveling period in Urumqi was from May to September, and April was the month turning from unsuitability to suitability, October was the month shifting from suitability to unsuitability, and the period from November to next March was not suitable for travel; ② During the study period, both the air temperature and precipitation were increased, wind speed was reduced, the change of relative humidity was slight, the climate was trended towards a warmingwetting pattern, and such climate would attract more and more visitors and increase their comfort degree during their trip; ③The suitable travel duration would be extended, and this change would promote the tourism development in Urumqi.
