Morphodynamic changes at sandy coasts, as are dominant in the Netherlands, are typically monitored at yearly intervals by means of airborne laser scanning. Meanwhile it is recognised that beach morphodynamics is not a regular process and is strongly correlated to meteorological conditions. A series of 25 terrestrial laser scans of a beach experiment is analysed, obtained during a time period of 88 hours, characterised by changing weather conditions including strong wind and rain. It is shown that after a conversion to a cylindrical grid, different deformation regimes can be identified and rates of elevation changes below 1 mm per hour can be detected. Simultaneously, an analysis of distances between targets through time demonstrates the sensitivity of the used measurement set‐up to the harsh weather conditions.
