The phenomenon of the heat island can to be defined as a thermal anomaly where the temperature of the surface of urban air more is raised of what the surrounding areas. The heat island can happen in different scales, as much in localization inside of the proper city (it scales local) how much in the difference of the temperature between the urban and agricultural area (MOREIRA, 2009). The study of the urban climate if it bases on a line of research of the responsible climatologia for the understanding of the climate of the city, focusing, inicialmente, a local space analysis (local climate) that one extends the regional levels (regional climate) and global (zonal climate), being distinguished, in each scale, the urban influence (BIRTH apud COLTRI, 2006). The occupation process brings deep changes for the urban environment ‘ ‘ a metropolis without adequate planning of the use of the ground, with absence of adequate parameters of verticalizao and occupation, over all where it grows to a fast speed and with few resources technician, can at risk place the quality of life of its inhabitants (MOREIRA apud LOMBARDO, 2009). According to Coltri apud Pear tree (2007) factors related to the materials used in the constructions, density of urbanization, amount of green area, use of the ground agricultural can intensify and aggravate the effect. Studies with emphasis in the Urban Climatologia if dedicate to answer questions on: heat islands; atmospheric humidity; local circulation; pollution of air; fog occurrences; precipitation in the cities; climate and urban planning.
