This study is the first detailed study of human comfort and discomfort in the study area. More than one index was applied all year-round, which can be a basis for future studies. The climate of the study area is divided into three divisions which differ completely from each other. The first is the climate of the Coastal Plain, which is hot in summer and moderate in winter, the second is the climate of the Sarawat Mountains, which is generally moderate in summer and cold in winter, and the third is the climate of the Eastern Plateaux which is hot in summer and cold in winter. These divisions of climate have a major impact on human comfort and discomfort. In order to achieve the study objectives, four indices were applied. These include the heat balance of the human body and water balance or sweating rates of the human body by Adolph (Griffiths, 1976). Also, the temperature-humidity index (THI) by Thom (1959) was applied, and a bioclimate classification by the same author was applied to the THI values. In addition, the temperature-vapour pressure index (TVI) developed by the Atmospheric Environment Service in Canada (1976) was applied, and the bioclimate classification by Masterton and Richardson (1979) was applied to the TVI value for all months. Also, a chapter about tourism has been included, to show the potential of the study area for tourism in terms of other factors apart from a climatic perspective. This chapter provides general information about potential attractions for tourism, such as sports/activities, ancient civilizations, and cities/towns, etc. Equations were created for the temperature-humidity index (THI) and the temperature-vapour pressure index (TVI), from which the values of both indices can be calculated for any location in the study area. A level of comfort and discomfort was added to the TVI to make it suitable for the study area. Maps for human comfort and discomfort were made for both the THI and the TVI for all months.
