Urbanization is a global phenomenon and more than two thirds of the human population will live in urban areas by 2030, as predicted by the United Nations - UN. Rapid and poorly managed urban growth is often associated with increasing environmental degradation causing several negative impacts, among them, the increase in temperature within these urbanized areas. In this way, the development of this work has os its generais objective to carry out a thermohygrometric evaluation in an intermediate urban area, called ZUI, in the city of SinopMT, and as specificities of this objective, to collect climatic data of air temperature and relative humidity through mobile transect, at 12 points in an urban region belonging to ZUI. For data validation, the same microclimatic variables were collected through a fixed commercial micrometeorological station installed by the research author, at a distance of 1 (one) kilometer from the starting point (point 01) of the mobile transect, a region to which it has similar urban characteristics and which can be safely installed throughout the collection period. The collections took place over a period of 12 (twelve) months, divided between the years 2020 and 2021, covering the seasonal periods (hot humid and hot dry). The mobile transect was carried out with instrumentation coupled to a motor vehicle, in a path of approximately 15 kilometers. As a result, point 08 recorded milder temperatures (max. 33.5 ºC) in the hot dry period, (min. 22.9 ºC) in the hot humid period, located in a region with relative tree density, and greater distances constructive. The highest temperatures were recorded at Point 03 (max. 38.6 ºC) in the hot dry period, located in a region with morphological characteristics containing narrow lanes, fully paved sidewalks, without the presence of trees on public sidewalks. The data obtained by the fixed meteorological station, comes to confirm and validate the data and climatic behavior of the region. In view of the results, it is concluded that afforestation is a contributing factor significantly in improving the thermal comfort of urban spaces, attenuating the effects of incident solar radiation in the environment. Evidencing the need to use vegetation to improve the quality of life in urban areas, avoiding the formation of microclimatic phenomena such as “heat islands”. It is necessary that the planning of cities does not ignore the climatic aspects, and treats with relevance and need the creation of green spaces and well wooded in order to obtain better thermal conditions favorable to the comfort and health of the population.
