    Description: Conocer los patrones de circulación costera es fundamental para gestionar adecuadamente la franja litoral, especialmente en áreas con alta presión antrópica. Con el objetivo de determinar las características de las corrientes costeras en el golfo de Urabá, se midieron y analizaron los patrones estacionales de circulación superficial durante las épocas de mucha y poca lluvia a lo largo de 6 km de costa, entre las espigas litorales de punta de Las Vacas y punta Yarumal del municipio de Turbo, Antioquia. Estas mediciones se realizaron con derivadores superficiales, que fueron lanzados en diversos estadios de la marea y rastreados durante periodos cercanos al ciclo semidiurno. Las mediciones in situ se analizaron considerando la evolución de la marea y los vientos observados en una estación climática ubicada cerca del golfo. Los patrones de circulación mostraron un comportamiento diferente durante las dos estaciones del año. La temporada de mucha lluvia, con vientos del sur, presentó trayectorias hacia el norte y la temporada de poca lluvia, con vientos del norte, las trayectorias fueron hacia el sur. Aunque los patrones de circulación mostraron una fuerte relación con la marea y el viento, las trayectorias de algunos derivadores se modificaron localmente por la presencia de geoformas como las bahías de Turbo y El Uno.
    Description: Good knowledge of the coastal circulation patterns is essential for a proper management of the coastline, especially in areas with a high anthropic pressure. In order to determine the main characteristics of the coastal currents in the Gulf of Urabá, the seasonal patterns of surface circulation were measured and analyzed during times of high and low rainfall along 6 km of coastline, between the Punta de Las Vacas and Punta Yarumal coastal spit systems, in the municipality of Turbo, Antioquia. These measurements were made with surface drifters, which were launched at different tide stages and tracked for time periods based on the semi-diurnal cycle. The in-situmeasurements were analyzed alongside tide and wind data from a climatic station located near the gulf. The circulation patterns behaved differently depending on the season of the year. In the rainy season, with southerly winds, the drifters moved mainly towards the north while during the dry season, with northerly winds, all the drifters moved to the south. Although the circulation patterns showed a strong relationship with the tidal cycle and wind conditions, the Turbo and El Uno Bays modified some of the drifter’s paths.
