September 2035 is the perfect month for a Marbella boat rental. With sea temperatures holding at 27°C, air temperatures around 28°C, and the summer crowds thinning out, the shoulder season delivers ideal conditions for a day on the water. Whether you're celebrating the end of summer or just escaping the heat, our fleet departs from Puerto Banús with everything included – skipper, fuel, drinks, snacks, and IVA. Here's everything you need to know about the weather, the best boats, and how to make the most of your charter.
September Weather in Marbella: What to Expect
September 2035 brings stable Mediterranean weather. Expect daytime highs of 28°C, cooling to 21°C in the evening. The sea is at its warmest – 27°C – making swimming a highlight. Rainfall is minimal (only 2–3 days on average), and you'll enjoy around 9 hours of sunshine daily. The wind typically blows from the east at 10–15 knots, creating a gentle chop that's comfortable for all boat sizes. This combination makes September one of the best months for a Marbella boat rental.
Why Choose the Shoulder Season?
The shoulder season (September–October) offers distinct advantages over peak summer. Marinas like Puerto Banús and Marbella Marina are less crowded, meaning easier parking and more relaxed boarding. Prices for some charters are lower, and you'll have more flexibility with booking dates. The water is still warm enough for swimming, and the sun isn't as intense – ideal for families or groups who prefer milder conditions. Plus, the famous Marbella sunset views over La Concha are spectacular in September.
Best Boats for September Charters
For small groups (up to 9 pax), the Astondoa 40 (€749/2h) is a top choice – fast, comfortable, and perfect for a half-day trip. The Azimut 39 (same price) seats 11 and offers a spacious flybridge. If you want a full-day adventure with a jet ski included, the Mangusta 80 (€4,719/4h min) is unbeatable. For larger parties, the Azimut 58 Flybridge or Ferretti 94 can accommodate up to 12 guests. All boats depart from Puerto Banús and come with a licensed skipper.
What's Included in Your Charter
Every booking includes a professional skipper, fuel, insurance, safety equipment, and Spanish IVA (21%). Onboard you'll find unlimited water, soft drinks, beer, white wine, cava, and light snacks. You're welcome to bring your own food and music. All boats are equipped with Bluetooth speakers, sun pads, and a bimini for shade. No hidden costs – just show up and enjoy.

Booking Tips for September 2035
Even in the shoulder season, popular boats like the Mangusta 80 and Azimut 58 Flybridge fill up quickly on weekends. We recommend booking at least 2–3 weeks in advance. For the best value, consider a half-day (4h) charter in the morning when the sea is calmest. If you're flexible, a weekday booking often has more availability.
