In recent decades, accelerated urban growth has developed a generally warm microclimate within cities, relative to its surroundings. One of these microclimates is called Intra Urban Heat Islets (IUHI). Here, the IUHIs in the city of Bogotá were identified and characterized by calculating their intensity and analyzing variables such as land cover, wind speed, relative humidity, and solar radiation. It was found that in the city a main islet is formed in the southwestern polygon, where there is a heavy industrial zone with a large number of buildings. In addition, it is observed that the temperature around the city varies depending on both the climatic season and the diurnal cycle. Thus, IUHIs are more intense during the dry season, and in some cases, they only occur during daylight hours. These abnormal values in air temperature are mainly due to the density of the vegetation cover, which, according to observations, tends to reduce the intensity of the islets. As for the meteorological variables, they have a heterogeneous influence on IUHIs in different areas of the city and no correlation pattern was identified.
