The present research intends to identify the effects of urban sprawl of metropolis on tourism-climate index oscillation. To do this research, two types of data have been used. The first type includes climate data such as minimum monthly temperature average, monthly temperature average, minimum relative humidity rate and monthly relative humidity average, average of wind speed, duration of sunshine and monthly rainfall, and the second component includes parameters related to urban sprawl components of Tehran city such as number of population, density, expansion and number of automobiles per 100 persons. In this research in order to identify climate-tourism range for different months TCI coefficient has been used. Based on the results taken from the average of three 18-year periods using TCI index, it has been concluded that time oscillation is seen for the majority of months in qualitative and quantitative range of climate-tourism coefficient. In a way that these time oscillations of TCI has positive trend for some months and negative for others. In the next step after making correlation between the components of urban sprawl of Tehran city with TCI index, it has been concluded that in April, May, September and November, the results show that the components of urban sprawl of the city has direct effect on providing more suitable climate-tourism conditions, however in June, July, August and September, the components of urban sprawl of the city has had a negative effect on TCI index. But in general, considering the outcome results for annual statistics, we can conclude that urban sprawl of metropolis of Tehran has had a negative effect on TCI index and this factor can be followed by undesirable conditions for Tehran in view of climate comfort in future and it will be considered as a difficulty in view of biologic conditions for tourists.
