Heat waves have been more recurrent through a global warming scenario. Extreme temperatures have some rate of human thermal discomfort due to heat, which can cause and potentiate comorbidities and lead to death in extreme cases. This study evaluated the occurrence of heat waves and their relationship with human thermal discomfort in the Tapajós National Forest region, located in the state of Pará, Brazil. Data were obtained from the conventional weather station of the National Institute of Meteorology, during the period from 1971 to 2019. Human thermal comfort was estimated from the Thom Discomfort Index (DI), which is an empirical methodology capable of representing the thermal environment by means of data of maximum temperature and relative humidity and heat waves were estimated using the CTX90pct index. with higher rates of discomfort in the less rainy season and potentiated in periods of drought in the region. The DI showed that in the presence of heat waves, the discomfort caused by heat felt by the population increases by about 40%. The results presented added to the increase in discomfort can cause effects on public health and socioeconomic activities in the region.
