In this study, spatial properties and potentials of Iran bioclimatic in seasonal scale have been studied. To do this, physiological equivalent temperature (PET) was calculated for 101 synoptic stations using GIS software. In the first stage, bioclimatic analysis of each season was carried out, and the obtained data were correlated to the tourism field. According to the obtained results, bioclimatic variation of Iran is significant; spring season has the best conditions in terms of climatic comfort and autumn is in the second rank. In bioclimatic map of summer, thermal stress is dominant. Cold stress of winter is more intense and widespread than thermal one.
