Thermal pollution of marine water adversely affects the local environment and ecosystems due to consequent rise in water temperature. Industrial activity, particularly cooling process, is the main reason of marine pollution. The current study is focusing on thermal coastal water pollution in Jeddah city (west KSA). It is aimed to estimate water temperature using satellite data, particularly thermal bands. Temporal and spatial variation, of sea surface temperature (SST) are followed using Landsat 5 Thematic Mapper (TM) scenes, and Landsat7 Enhanced Thematic Mapper (ETM), acquired in (September 1990), (October 2000) and (November 2013). Thermal infrared (TIR) remote sensing data were used to calculate Sea Surface Temperature (SST). It was found that the highest SST value, recorded within the period 1990-2000, was (29°C), whereas the highest (SST) in the year 2013 jumped to be 33°C. The lowest (SST) found within year 1990-2000 is (26°C), while (29°C) was found in year 2013. The increase of SST, during 1990-2013, is an evidence of thermal pollution occurring along Jeddah city coastal area. It is expected that such pollution has its impact on local aquatic organisms status and activates (i.e. metabolic rates, reduction of cell wall permeability, osmotic pressure, enzyme systems … etc.).
