The large concentration of people in urban areas in a tropical region (hot and humid) is one of the recurring problems when it comes to thermal comfort. The objective of this study was to analyze the thermal comfort of the municipality of São João de Pirabas-PA. Meteorological data (air temperature and relative humidity) were collected using 3 HOBO U10 model microloggers, programmed to record every 30 minutes, from 8 am to 6 pm. They were installed inside suitable shelters in order to protect them from external interference. Data collection took place from June 20 to 22, 2023, simultaneously in predefined locations, taking into account surface coverage. In this research, the following were used: Heat Index (HI), Effective Temperature Index (ETI) and Thermal Discomfort Index (TDI). The daily air temperature averages, from the three previously exposed locations, were around 30.4 °C; 28.1 °C; 30.2 °C, while the relative humidity varied between 69%; 83%; 70%. The HI showed little temporal variation, the ETI and TDI showed differences between point 1 (discomfort) compared to the others. The city needs measures to improve thermal comfort.
