Study on surface and subsurface temperature is an important factor in managing coastal processes such as biological activity, heat momentum and exchange, interaction with the surrounding air and climate change. Environmental conditions and different geographical location lead to the temperature difference in day and night and in different seasons. It may temporarily affect air-sea interactions by altering the heat and gas fluxes, atmospheric circulation and the height of the atmospheric boundary layer. Thermal remote sensing and new sensors such as SEVIRI, HyspIRI, AMSR-E, and MIRAS can be used to simulate sea subsurface temperature. Meanwhile, accurate results of ocean subsurface temperature can be obtained by precise determination of surface parameters like wind speed, radiation/heat balance at the surface, SST and SSH/dynamic height, mixed layer depth, thermocline bottom depth, sea surface salinity, conductivity, etc. Due to the important role of subsurface and deeper ocean temperatures on global warming nowadays, proper and successful estimations of complex nature of SST and ocean subsurface temperature by considering most effective parameters are challenging. Regarding the horizontal and vertical surface and subsurface temperature anomalies, it can be concluded that most diurnal warming can occur at shallower depths. Further the temperatures will decline away from the coast. Studying the diurnal temperature of sea showed that high peak almost was occurring between 10:00 and 15:00 SST in March, April and May, but it was seen between 11:00 and 16:00 in June, July and August. In all month, minimum values were observed between 02:00 and 04:00 almost. A peak decrease was observed during the transition from late winter to summer.
