%X Analysis of historical data including coastal and open ocean data provides a quantitative description of the characteristics of the sea surface annual signal and of the interannual anomalies in the Eastern Equatorial Atlantic ocean. The annual signal has a larger amplitude than the interannual anomalies but has considerable spatial variations. In two regions, namely the Northern coast of the Gulf of Guinea and the equator, both annual and interannual variability are particularly large because of a seasonal surfacing of the thermocline. Eastward advection of warm water by the countercurrent system, local rain and runoff of great rivers could contribute significantly to the seasonal and interannual STT variability. Interannual anomalies have alarge spatial extent and can affect the whole basin for several months or a year. In the Atlantic as in other regions of the world ocean, the long-term trend shows a general increase of STT from the beginning of the century to the sixties and a decrease until now.
