In this study, the bioclimatic comfort situation of the Isparta city center was examined for outdoor recreation. It is important to determine the suitable times and days of the year for bioclimatic comfort in recreational planning. To determine the suitable times and days, one day was divided into two-hour parts (10.00-18.00), and the months were divided into 10-day periods. The climatic data belonging to the determined area were obtained by the portable weather station, and the bioclimatic comfort was evaluated using these data. The physiological equivalent temperature (PET) index was used to calculate the bioclimatic comfort conditions. Calculations of the PET index were performed by the program RayMan 2.1. The PET values were presented according to bioclimatic comfort classes by graphics of percentage distribution daily and monthly. The research results indicate that in the city center of Isparta, the most comfortable days predominantly occur at 10.00 in October (38.3%), at 12:00 in May (28.6%), at 14:00 in May and October (28.3%), at 16.00 in May (41%), and at 18.00 predominantly between June and October (36.6%). There is no comfortable interval during summer, especially in August, because of the high temperature and solar radiation. Furthermore, the climatic conditions are colder in the morning and evening and warmer in the afternoon. |
