  abstract = {{T}his study analyses a 4.5 year ({S}eptember 2009-{M}arch 2014) time-series of remotely-sensed data of altimeter significant wave heights to describe the temporal and spatial variability of ocean swells along the northern coast of the {G}ulf of {G}uinea. {T}he {NOAA} {WAVEWATCH} {III} ({NWW}3) wave model data were used with altimeter data to determine the origin of the swells that occur along the coast of {C}ote d'{I}voire in {W}est {A}frica. {W}e show that the ocean swells along the northern coast of the {G}ulf of {G}uinea are generated in the {S}outhern {O}cean and then propagate from south to north in the {S}outh {A}tlantic {O}cean, before turning south-west to north-east close to the coast. {T}his finding corroborates previous studies in this area. {T}he remotely-sensed and {NWW}3 significant wave height data captured the strong swells observed along the coast of {C}ote d'{I}voire from the period 28 {A}ugust-3 {S}eptember 2011, which were responsible for an extreme erosion event of more than 12 m along that country's coastline. {T}his extreme event was triggered by a strong storm in the region between 40 degrees and 60 degrees {S} that occurred eight days previously in the {S}outh {A}tlantic. {T}he waves propagated as swells at a speed of about 875 km day(-1) before reaching the northern {A}frican coast.},
