Why September is Ideal for Boat Rentals
Peak tourist season winds down after mid-September, meaning fewer boats on the water and more availability at the marina. Sea conditions are stable, with minimal swell — perfect for families, couples, or groups who want a smooth ride. The water is still warm for snorkelling at Cala del Faro or Cala Cortés. You also get the benefit of lighter winds compared to July and August, making for a more relaxing cruise along the Costa del Sol.
Best Routes for a September Charter
From Puerto Banús, head east to Marbella Marina and the Golden Mile, or west towards Estepona and Sotogrande. A popular 4-hour route covers Cabopino and the dunes, while an 8-hour charter lets you reach the quieter coves near Cala del Faro. The sea state in September makes these runs comfortable on any of our fleet. For a shorter trip, the 2-hour Tier A charter on the Astondoa 40 or Azimut 39 gives you a taste of the coast without committing a full day.
