The aim of this research was to analyze the microclimatic conditions in cycle routes in the city of Três Lagoas/Ms, with emphasis on its arboreal feature an analysis of urban environmental quality in relation to microclimatic comfort to users.To this end, several methodological procedures were applied, distributed in different stages, starting with a literary review, followed by data collection on cycle routes, as well as spatial distribution, quantification and description of these. The characteristics of the vegetation cover was also analyzed based on the normalized difference vegetation index (NDVI) obtained through the use of Sentinel 2 satellite images, in different seasons, in addition to describing the vegetation cover through field work. In addition, based on Landsat LC8 satellite images, Earth Surface Temperature Charts were drawn up, which were analyzed together with air temperature and relative humidity data collected from a mobile transecto performed at three times throughout the day (08:00, 14:00 and 20:00). Both surface temperature charts and moving transectos were performed seasonally. Based on these steps, the classification of the intensity of heat islands and islands of freshness along the path of the mobile transecto was also applied, for the three times, relating the thermal data of the bike paths to those of the rural area through the installation of fixed sensor for time data collection. Also based on the transecto, the Thermal Discomfort Index (RTD) was calculated for each time along the bike paths. In order to corroborate the results and understanding of these, letters of guidance were drawn up in order to correlate them to the thermohygrometric results. Finally, a questionnaire was applied raising a brief profile of cyclists, to apprehend their opinions/perceptions about the environmental quality conditions in the cycle routes of Três Lagoas. It was possible to verify that the Routes with the highest biomass index, 03 and 05, showed the lowest temperatures and higher humidity at 08:00 and 20:00, with an inversion at 14:00, except in the summer, which was this inversion on Route 06. Regarding the heat/freshness islands, these are dynamic and do not necessarily follow a pattern of occurrence. From a socio-spatial point of view, it is possible to identify several points that make these paths for cyclists fall short. However, a relationship between the presence of vegetation with lower temperatures, and consequently higher humidity, is concluded, but it is still relevant to take into account that the urban climate is dynamic and distinct throughout the spaces of a city, being pertinent planning that aimed at meeting the peculiarities, both physical and social.
