  abstract = {{S}ea level variations at the coast can have drastic environmental and socio-economic impacts in particular in the context of an ever-increasing coastal population and anthropogenic climate change. {R}egional to global climate variability influences all these factors and exerts a strong control on the coastal sea level over a wide range of time scales. {H}ere, we focus on understanding interannual changes which is paramount to improve interannual forecasting systems as well as to constrain and reduce uncertainties on the secular trend in global mean sea level. {W}e consider the coastal total water level ({TWL}) as the compound effect of three main components: the wave setup, mean regional sea level anomaly (i.e., steric and ocean circulation influences) and atmospheric surge (i.e., influence of local wind and surface atmospheric pressure). {T}o understand their variability at a global scale, we focus on the effect of four climate modes that affect the major oceanic basins: the {E}l {N}ino {S}outhern {O}scillation ({ENSO}) and {P}acific {D}ecadal {O}scillation ({PDO}), the {N}orth {A}tlantic {O}scillation ({NAO}) and the {S}outhern {A}nnual {M}ode ({SAM}). {T}he contrasted regional influence of these different climate modes on the interannual variations of {TWL} components are quantified. {R}esults suggest that even if the regional mean sea level is overall the main contributor to the interannual variations of {TWL} variations at the coast and mostly related to {ENSO}, the contributions from wave setup and atmospheric surge are not negligible in particular at high latitudes and mostly related to the {NAO} in the {N}orthern {A}tlantic and to the {SAM} in the {S}outhern {H}emisphere. {S}uch influences from the {NAO} and {SAM} can be seen far away from their extratropical regions of action due to their atmospheric forcing of ocean waves that can significantly propagate their imprint towards tropical areas. {I}mplications for interannual to decadal forecasts of the coastal {TWL} and related hazards are discussed in the light of regression statistical models and the climate modes own predictability.},
