This paper gives the reader an idea about the climate in Gaza Strip and the West Bank. Gaza City has been chosen to represent the Gaza Strip, while Jerusalem has been chosen to represent the West Bank. Climatic data like the dry-bulb temperature, relative humidity and average annual solar intensity are provided. The bioclimatic charts are introduced to illustrate the position of both cities with respect to the human comfort conditions. From these charts, one can estimate the possibility of using passive and/or active heating and cooling in winter and summer in the region.
