Abstract
The winds play an important role in the arrival of sargassum to the Cuban coasts, since these marine macroalgae, lacking their own swimming, depend on the oceanic and atmospheric circulation for their movement. For this reason, the objective is to analyze the direction and speed of the wind on the coasts of Cuba, highlighting the winds that could have favored the arrival of sargassum. In this research, wind data from Cuban coastal stations were used. It was shown that the winds that most frequently influenced the northern coast, both in the rainy period and in the dry period, are those of the first quadrant, with the winds from the north, north-northeast and east being the most representative, which They allowed the arrival of sargassum towards Matanzas, Havana, Villa Clara and Guantánamo. On the south coast, in the rainy and dry periods, the most influential winds were those from the second quadrant, with the winds from the south-southeast, southeast and south being the most predominant, which favored the arrival of sargassum towards Matanzas, Cienfuegos, Ciego de Ávila, Camagüey, Santiago de Cuba and Granma, as well as in the special municipality of Isla de la Juventud. Furthermore, it was shown that, in the western and central region of the archipelago, both on the north coast and on the south coast, the winds were weak, less than 16 km/h, while on the rest of the coasts they were between 17 and 20 km/h.
