Thermal comfort is a subjective sensation, so it is defined as a state of mind that reflects satisfaction with the thermal conditions of the environment in which each person is found. In an educational context, thermal performance in public schools in the city of Crato - Ceará has been of little importance. Schools are collective spaces that deserve special attention and good planning, aiming at good weather conditions and comfort for the development of school activities. Therefore, this research aimed to evaluate the microclimates associated with the degree of thermal comfort of students and staff of a public school located in a district with urban heat island registration in the city of Crato/CE Regarding the methodological procedures, the bibliographic survey was made based on the Urban Climate System (Monteiro,1976) with emphasis on the thermodynamic channel and on the thermal comfort in school environments, then the school was elected; climatic data (temperature and relative humidity) were collected using a portable digital Thermohygrometer; mod. HT70 in two episodes: December 11, 2018, hot and dry period and April 3, 2019, wet and rainy period, during two shifts: morning and afternoon, followed by the application of questionnaires on the thermal perceptions of young schoolchildren and staff. For the analysis we used the Thom Comfort Index (1959). This index describes the thermal sensation that a person experiences due to variations in the climatic conditions of an environment. Based on the data collected and analyzed, the results presented situations of thermal comfort and thermal discomfort in both periods: hot and dry, humid and rainy in the school environment. When applying the questionnaires in the hot and dry period, temperature values from 25° C to 30°C and relative humidity from 53.8% to 68.5% were recorded, and it was found that most respondents preferred to feel a little colder.
