Summary: Urbanization process causes many changes to the natural environment, among which the removal of a large part of vegetation and the alteration of surface materials, besides the inclusion of buildings and production of pollutants. These environment alterations contribute to climate changes, causing for the city what is called urban climate. Vegetation can be used, among other aspects, in order to reduce thermal discomfort commonly present in urban environment, mainly in cities with tropical weather. The goal of this research was to quantify the influence of the presence of vegetation in urban climate, due to the interactions soil-vegetation-atmosphere worked out from simulations with ENVI-met 3.1 software. The methodology was established from the holding of microclimatic measurements for calibration of the model for the climate situation of the research area, as simulations were later carried out, aiming to evaluate the influence of vegetation in urban comfort, based on general thermal maps of the area, generated by the plugin Leonardo, and graphics of specific points, highlighting that the territorial clipping was an area previously selected on Mata da Praia neighborhood, in the city of Vitoria, ES, Brazil. From thermal maps, the temperature difference in areas with larger amount of vegetation and also humidity was verified. The more wooded stretches, whether in the squares and park, or in the streets, had lower temperatures and higher relative humidity registered, both in the summer and in the winter, in most of the analysed schedules. From the results, it can be affirmed that the presence of vegetation in the urban environment contributes to mitigate thermal discomfort, as it was registered a maximum temperature difference of up to 3.5º C in summer and 2.5º C in winter, and 25% of humidity in summer and 32.5% in winter, in extreme situations.
