This article refers to a study conducted on Mãe Bonifácia Park, a large green area of the central region of Cuiabá, MT, between November 2007 and October 2008, aiming to evaluate the influence of the urban architecture interventions on the thermal environment of the place, and to examine possible impacts of these on the heat stress level that are exposed the users organisms. Different kinds of microclimates were observed by steady measurement, placed in the main square of the Park, and by mobile measurement, along trails. The application of the methodology indicated that there were attenuations in the air temperature up to 3.0 °C in the narrower trails, where the native vegetation was preserved. However, in the park built spaces a maximum elevation up to 3.2 °C was observed, indication the need for special care on the practice of physical activities, especially in the dry season. These results suggest that there is a direct relationship between the soil occupation standard, topography, and vegetation characteristics in each micro-space, on the thermal environment of the place. It was also possible to conclude that interventions defined by the design were not adequate for the severe climate of the region, increasing the perception of thermal discomfort.
