  abstract = {{I}n the context of global mean sea level rise, understanding the drivers of relative sea-level ({RSL}) at the coast is of major importance for coastal environments research and management. {S}ince the 1990s, the combination of satellite altimetry observations with in situ tide gauge data has provided a better understanding of coastal sea level variability, but challenges remain to quantify the relative contributions of possible drivers (oceanic, vertical land motion ({VLM}), atmospheric and wave). {H}ere, over the period 1993-2015, we combine concurrent observations from satellite altimetry, tide gauges, and oceanic model hindcast in order to identify the predominant drivers responsible for long-term variability of {RSL} at 434 coastal locations worldwide. {W}e found that the dominant driver of the {RSL} trend is the ocean components in 76% of the cases, {VLM} in 17% and waves in 7%. {I}nterestingly, no significant trend in the wave setup was noted over the period considered at most of our coastal stations. {H}owever, at some locations, we found significant correlations between the wave setup hindcasts and {VLM} data. {M}oreover, we evidence a substantial variance reduction in the {VLM} once corrected for the wave setup. {W}e therefore recommend future studies aiming at {VLM} estimation to consider applying wave setup corrections to improve the comparability of the tide gauge and satellite altimetry measurements.},
