September in Marbella is the sweet spot for boat rental: the Mediterranean has warmed to a bath-like 26°C, the sun still shines for 10 hours a day, and the August crowds have thinned out. If you're weighing up a charter, this shoulder-season month offers the best balance of summer conditions and autumn tranquillity. Here's what you need to know about the weather, the sea, and which of our Puerto Banús-based boats fits the bill.
September Weather at a Glance
Average air temperatures hit 28°C in the afternoon, dropping to a pleasant 20°C after sunset. Sea temperatures peak at 26°C—warm enough for long swims without a wetsuit. You can expect roughly 10 hours of sunshine per day, with UV index still climbing to 6-7, so pack high-factor sunscreen. Rain is rare: typically just 2-3 days across the whole month, and usually short-lived.
Sea Conditions and Swell
Swell in September is modest, averaging 0.5-1.2m (3-4 feet) offshore. The dominant wind is the Levanter, blowing from the east at 10-15 knots in the afternoon. Mornings are often glass-calm, making them ideal for a smooth cruise. Your skipper will monitor conditions and can adjust the route to keep you in sheltered waters if the breeze picks up.
Why Choose the Shoulder Season?
August in Marbella is vibrant but busy: anchorages fill up, and marinas buzz with activity. September brings a relaxed pace—you'll find more space at Cala del Faro and Cala Cortés, and a quieter Puerto Banús. Water temperatures are still high, but the air feels fresher. It's the perfect month for a leisurely day out, whether you're swimming, snorkelling, or simply soaking up the sun on the flybridge.
Our Boats for September Charters
All our boats depart from Puerto Banús, so you're steps from the action.

If you're up to 11 guests, the Azimut 39 (12.5m) offers a spacious cockpit and a smooth ride. For a luxury day with a free jet ski, the Mangusta 80 (24m, 12 pax) is the showstopper.
