The paper compares the ocurrence patterns of intertidal morphologies across two exposed beaches in the Bay ofCâdiz: Vistahermosa beach, in the south, and La Barrosa beach, in the north. Topographic profiles over a complete year in a monthly and a weekly secuence are shown. A roughly stable intertidal stage, named type I in Davidson-Arnott description, is obtained for La Barrosa beach. The intertidal morphologies detected in Vistahermosa beach are less stable and related to type II in Davidson-Arnott description
