The frequency and geographic distribution of extreme weather events began to change as a result of global climatic changes and anthropogenic changes in urban space that influence the urban microclimate, affecting the mesoclimate and the macroclimate. This research aimed to relate the microclimatic and anthropogenic adaptations that occurred in five portions in an urban area in the Brazilian Savanna named Cerrado between the years 2011–2012 and 2016. As a methodology, the nocturnal moving transect technique was used to measure micrometeorological variables such as air temperature and relative air humidity, and the maximum likelihood classification technique to classify and quantify the types of soil cover found in the two periods studied. In this way, it was possible to observe an increase of 1.45 ℃ in the intensity of the urban heat island and a decrease in relative air humidity of 3.32%, associated to areas with up to 17.173% of impervious materials such as concrete and asphalt, and decrease of up to 22.20% of vegetal cover. Evidenciating the importance of several studies on the use of materials with low thermal diffusivity and application of mitigating measures as an increase of vegetated areas, thus making the public awareness of the impacts of unplanned urbanization.
