Spatial and temporal variability in the water temperature in three surface, subsurface and near the bottom layers were investigated in the Suez Gulf. The gulf under study was divided into five lateral sectors, where temperatures were distributed horizontally and vertically to detect the spots of  increase and decrease as well as what may have an impact on both. The pronounced seasonally fluctuations of water temperature were observed at the three layers. The water temperatures were recorde at their highest at the highest latitude (region E), resulting from the natural condition of mixing the gulf water with the worm Red Sea water and the highest intensity of solar radiation. Whereas, at the lowest latitudes (regions A and B), water temperature was at its lowest as a result of the natural condition of the land cooling and the huge human activity in the northern part of the gulf. A fluctuation was noticed in the water temperatures between 17.10 & 27.32^oC at the surface, 17.09 & 27.06^oC at the subsurface, and 17.00 & 26.86^oC near the bottom. Based on the vertical distribution of water temperature, a rising water temperature was recorded in the east of the sectors, while decreasing westward.
