Abstract: Within the general framework of the natural environment of the Red Sea Region and, with the two cities of Port Sudan and Erkowit, which are chosen as a case study, this study tackled the climatic factors, which influence human feeling of comfort and discomfort. The objective of this study is to conduct an analysis of thermal conditions, in the Red Sea Region, so that they could be used in the different processes of planning. Also, the study tried to examine compatibility and incompatibility of the characteristics of the two climates of Port Sudan and Erkowit and the extent of their impact on human comfort. Moreover, one of the aims of this study is to count the number of days where the weather is either uncomfortable, hot and stressful, to the extent that it may hamper the wheel of work, or it is so much comfortable that it could encourage work, increase productivity and enhance tourist activities. While the study relied on the statistical method in the analysis of the climatic data of the two cities and used statistical styles and statistical models, which were finally, transformed into charts, shapes and graphs, a descriptive and analytical method is adopted for the display of the obtained information. In this context, the study adopted a critical and analytical approach in order to define the criteria, which determines the degree of human comfort and discomfort and reached the conclusion that Heat-Humidity Index could be the most suitable for the evaluation of human comfort in tropical coastal environments, because it relies on temperature and humidity as two basic variables for determining human feeling of comfort and discomfort. These two factors represent the most important climatic factors, which influence people's feelings towards weather and their feeling of comfort and discomfort, in the Red Sea Region. Therefore, the study used this Index as the basic index for the evaluation of the climates of the two cities of Port Sudan and Erkowit, in order to determine the human feeling of comfort and discomfort, together with its levels and degrees, based on the application of the IX equation of the same Index and according to the climatic data collected from the two stations (Port Sudan and Erkowit). The study has reached the conclusion that - despite the proximity of the tow cities- there is a clear difference in the mean monthly Heat- Humidity Index, between the two cities of Port Sudan and Erkowit, where Port Sudan witnesses uncomfortable climatic conditions during most of the months of the year. The weather during the period of May to November is a hot and unbearable weather, wherein an individual shows a strong feeling of discomfort and frustration. While the month of August is considered as the worst month among all the months of the year, the period from December to April is the most suitable period for human comfort, in Port Sudan city. The study has also reached the conclusion that in summer, daytime weather in Port Sudan is annoying and causes a strong feeling of frustration and fatigue. This makes it difficult for any individual to perform any activity, because any physical effort exerted by an individual will lead to the generation of an internal heat that should be equal to the effort he has exerted. Thus, the performance of any activity in high degrees of temperature and high humidity levels will lead to a strong feeling of frustration and fatigue and, may cause heat stroke. Heat-Humidity Index proved that Erkowit city enjoys comfortable climatic conditions, throughout the year, which encourages work, raises productivity and enhances tourism.
