<p>Coastal tourism has grown rapidly worldwide, particularly along Mediterranean shorelines where sandy beaches are major economic and recreational assets. However, intensifying summer tourism may alter natural beach morphodynamics through trampling, mechanical beach cleaning, sediment compaction, and infrastructure development. Semi-enclosed coastal systems are especially sensitive to such disturbances because of restricted sediment exchange and limited accommodation space. This study investigates the morphodynamic response of beaches in Al Hoceima Bay (Moroccan Mediterranean coast) to seasonal anthropogenic pressures associated with mass tourism. Beach profiles surveyed in June 2022 (pre-tourism season) and November 2022 (post-tourism season) were analyzed to quantify morphological changes and variations in the sediment budget. Five representative beaches were considered: Quemado, Calabonita, Sfiha, Souani, and Lharch. Morphometric analyses reveal marked spatial variability in beach response. Some beaches exhibit sediment accretion between June and November, particularly Calabonita and Quemado, whereas others show erosion, mainly at Souani and Lharch. These patterns reflect the combined influence of wave regime, geomorphological confinement, sediment availability, and anthropogenic pressure associated with peak summer tourism. Analysis of volumetric changes and normalized net budgets indicates that beaches with intense recreational use experience significant sediment redistribution, compaction, and berm modification. Results highlight that tourism-related disturbances may amplify natural seasonal variability in beach morphology, particularly during low-energy summer conditions when anthropogenic forcing becomes the dominant driver. The findings emphasize the need for integrated coastal management strategies to regulate beach use, preserve sediment dynamics, and mitigate long-term erosion risks in Mediterranean tourist destinations.</p>
