New applications of thermal index, such as the Universal Thermal Climate Index (UTCI), via portable instrumentation of meteorological variables in open spaces may prove to be of fundamental interest for the improvement of present and future climate conditions in cities. The present study aims to analyze the influence of urban morphology on thermal comfort in open spaces through the use of a low-cost portable environmental monitoring system. For this, a case study was carried out in Curitiba, in which environmental variables and the sky view factor (SVF) of an urban area in a densely populated area of the city were evaluated, as well as the thermal comfort conditions in spaces open. The collected microclimatic data were used to calculate the UTCI, inflicting correlations between urban morphology and the condition of comfort and thermal stress. The results found point to a significant correlation among the data, with R² values of 0.82; 0.88 and 0.58 for 9:00, 15:00 and 21:00 on a summer day, respectively. The time of 15:00, in which the highest air temperatures were recorded, is consistent with the period of greatest correlation.
