Most studies on human thermal comfort are focused on assessing indoor environments; however, in recent years, researchers from various countries have been developing new strategies for assessing thermal comfort in outdoor Spaces due to the consequences arising from climate change. This study evaluates human thermal comfort through subjective assessment and the thermal PET and UTCI data. Through a longitudinal experiment conducted in a Zoobotanical Park in João Pessoa-PB, microclimate variables were recorded using a bioclimatic backpack, and subjective assessment questionnaires of sensation, comfort, and thermal preference were applied to pre-selected participants. The subjective responses were compared with PET and UTCI indexes. It was found that, along the transect, thermal sensations were intrinsically related to environmental conditions. Elements such as vegetation, exposure to solar radiation, and shading influenced thermal sensations and perceived comfort. The UTCI recorded a maximum value of 31.3°C, indicating moderate heat stress. The PET recorded a maximum value of 29.6°C, indicating mild heat stress.
