%X This article aims to assess the intensity and spatial distribution of surface heat islands over the urban area of Presidente Prudente, SP, Brazil, as well as its rural surroundings, on representative days of the four seasons. Presidente Prudente is located in the western state of São Paulo and has a continental tropical climate. It is in the transition area between the tropical, polar and equatorial masses, resulting in the concentration of precipitation in the spring/summer season, with a significant decrease in the autumn/winter season. For the diagnosis of surface heat islands, we used Landsat 8, band 10 satellite images, in the thermal infrared sensor (TIRS) 1, with spectral resolution of 10.6-19.11 m and spatial resolution of 100 m, but treated and provided with 30-meter pixel resolution by the United States Geological Survey (USGS) (band 10). The results showed that the shapes of the surface heat islands and their intensities varied according to the presence of precipitation on the days prior to when the images taken. In the representative images of the rainy seasons (spring/summer), temperature differences between urban and rural targets were higher than in the less rainy seasons (autumn/winter). Thus, the presence of precipitation proved to be a key variable in the analysis of the surface temperature in a tropical environment.
