Bioclimatic comfort defines the optimal climatic conditions in which people feel healthy and dynamic. Bioclimatic comfort mapping methods are useful to urban managers and planners. For the purposes of planning, climatic conditions, as determined by bioclimatic comfort assessments, are important. Bioclimatic components such as temperature, relative humidity, and wind speeds are important in evaluating bioclimatic comfort. In this study of the climate of Kastamonu province, the most suitable areas in terms of bioclimatic comfort have been identified. In this context, climate values belonging to the province of Kastamonu are taken from a total of nine meteorological stations. Altitude (36-1050 m) between stations is noted for revealing climatic changes. The data collected from these stations, including average temperature, relative humidity, and wind speed values are transferred to geographical information system (GIS) using ArcMap 10.2.2 software. GIS maps created from the imported data has designated the most suitable comfort areas in and around the city of Kastamonu. As a result, the study shows that Kastamonu has suitable ranges for bioclimatic comfort zone. The range of bioclimatic comfort value for Kastamonu is 17.6 °C. It is between a comfort ranges which is 15-20 °C. Kastamonu City has suitable area for bioclimatic comfort.
