The central theme of this dissertation was to evaluate the influence of the urban occupation in the variations of air temperature in Araraquara, a medium size city in the central region of the State of Sao Paulo. At first, temperature takings were made in places that are representative of the different tipologies of urban occupation in the city and the first results showed temperature variations up to 6oC in different places. Besides the measurements made in each of the places, some of the theoretically physical determining parameters of temperature variation were registered, such as: altitude, solar rays incidence angle at noon, roof area, vicinity to water, number of inhabitants per square meter and the percentage of paved, cemented, trees and grass areas. The quantification of the urban occupation design parameters was obtained through topographic maps and serial color orthophotography of the city area. Using the Cluster statistical analysis, the different places were put together according to the similarities of its urban occupation design parameters. Then, for each of the groups, multiple linear regression analyses were made to relate the thermal parameters to the quantified urban occupation parameters. These analyses allowed the elaboration of representative thermal maps of the typical summer and winter days. The observation of the maps showed significant differences between the urban perimeter and the intensely inhabited areas. The least thermal densities were observed in places of higher urban density, demonstrating, then, the occurrence of the urban thermal inertia.
