August in Marbella is the peak of summer: temperatures hit 28-31°C, the sea warms to a bath-like 24-26°C, and rain is almost non-existent. But staying on land can feel like a sauna. The smart move is to escape the heat at sea, where the breeze and the deep blue Mediterranean make even the hottest day bearable. In this guide, we break down what to expect from Marbella's August weather, how to pick the right boat from our Puerto Banús fleet, and how to make the most of your day on the water.
August Weather in Marbella: The Numbers
August is statistically the hottest month in Marbella, but also one of the driest. Here's what you can expect:
- Air temperature: 28-31°C highs, 22-24°C lows
- Sea temperature: 24-26°C — perfect for swimming
- Sunshine: 9 hours per day, UV index 9-10
- Rain: 0-2 days on average, usually a brief shower
- Wind: morning calm, afternoon levante 10-15 kts
- Humidity: moderate, 60-70%
These conditions are ideal for boating, but the afternoon breeze can create a light chop, especially outside the bay. Our skippers know the sheltered routes, so you can always find calm water.
Why a Boat is the Best Way to Beat the August Heat
At sea, the temperature feels 3-5°C cooler than on land, thanks to the constant breeze. You can also take a dip whenever you like — the sea is at its warmest in August. Anchor in a cove like Cala del Faro or Cala Cortés, and you'll have your own private swimming pool. Plus, every charter includes cold drinks (water, soft drinks, beer, white wine, cava) and light snacks, so you stay hydrated and refreshed.
Choosing the Right Boat for August
Our fleet at Boat Rental Marbella has options for every group size and budget. For August, consider these:
- Astondoa 40 (12.5m, 9 pax) — €749/2h, €2,299/8h. A great-value flybridge with shaded cockpit.
- Azimut 39 (12.5m, 11 pax) — Same pricing as Astondoa, sportier lines, more cockpit space.
- Azimut 58 Flybridge (17.6m, 12 pax) — Our most popular for families; air-conditioned saloon and huge shaded flybridge.
- Pershing 46 (14m, 10 pax) — For speed lovers; 40+ kts, but still comfortable.
- Mangusta 80 (24m, 12 pax) — €4,719 min 4h, includes a free jet ski. The ultimate luxury option for a special day.
All boats depart from Puerto Banús, so you can step aboard within minutes of arriving. If you're not sure which fits, message us on WhatsApp — we'll match you to the right boat based on your group and itinerary.
Best Times to Go: Morning vs Afternoon
In August, the sea is calmest in the morning (9:00-13:00). The levante breeze picks up around 14:00, so if you're prone to seasickness, book a morning slot. The afternoon offers warmer swimming and a lively vibe, but expect a slight chop. For sunset cruises, depart around 17:00 — you'll get the golden hour and a cooler return. Our 8-hour charters (10:00-18:00) let you enjoy both calm morning waters and a relaxed afternoon.
Top August Destinations from Puerto Banús
Here are our favourite spots to beat the heat:
- Cala del Faro — A quiet cove near the lighthouse, 15 minutes from port. Crystal-clear water, little swell.
- Cabopino — A sandy beach with a laid-back vibe, 30 minutes east. Good for anchoring and paddleboarding.
- Cala Cortés — A hidden gem between Marbella and Estepona, 25 minutes west. Deep water for jumping in.
- Estepona — A charming fishing town with a lively marina, 45 minutes west. Ideal for a lunch stop.
- Sotogrande — A luxury marina, 1 hour south. Great for spotting yachts and enjoying upscale restaurants.
Your skipper will tailor the route to the day's conditions, so you always get the best experience.

Booking Tips for August
August is peak season, so plan ahead:
- Book 2-3 weeks in advance for weekdays, 4-6 weeks for weekends.
- Weekday mornings are the least crowded — and the calmest.
- If you're flexible, a 4-hour charter (€749 for Tier A) is enough for a swim and a coastal cruise.
- For a full day, the 8-hour option gives you time to reach Estepona or Sotogrande and back.
- Check the marine forecast before you go — but in August, it's almost always good.

Frequently asked questions
What is the weather like in Marbella in August for boating?
August in Marbella is hot and dry: daily highs range 28-31°C, with sea temperatures at a pleasant 24-26°C. You'll get about 9 hours of sunshine and typically only 0-2 rain days. The main factor is the afternoon levante breeze (10-15 kts), which can create a light chop but is manageable for most boats in our fleet.
Is it too hot to be on a boat in Marbella in August?
No — that's the point of a boat charter. At sea, you get a constant breeze, and you can swim or anchor in cooler coves. Most of our boats have shaded flybridges or bimini tops. The sea breeze keeps air temperatures a few degrees cooler than on land, especially if you head toward Cabopino or Estepona.
What should I wear for an August boat trip in Marbella?
Light cotton or linen clothing, a swimsuit, and a light jacket for the evening return. Bring a hat, sunglasses, and reef-safe sunscreen (SPF 50+). The UV index in August is 9-10, so reapply every 2 hours. Non-slip boat shoes are ideal; flip-flops are fine on deck but not for boarding.
Which boat is best for a hot August day?
For a group of up to 12, the Azimut 58 Flybridge (17.6m) offers the most shaded deck space and a spacious saloon with air conditioning. If you want speed and a cooler breeze, the Pershing 46 (14m) hits 40+ kts. For a budget-friendly option, the Astondoa 40 (12.5m) at €749/2h is a solid choice.
Can we swim and snorkel in August?
Yes, August has the warmest sea temperatures (24-26°C), perfect for swimming. Popular spots include Cala del Faro, Cala Cortés, and the coves near Cabopino. Our skippers know the calmest spots, avoiding the afternoon chop. Snorkelling gear is available on request — just ask when booking.
How far in advance should I book a boat in August?
August is peak season, so book 2-3 weeks ahead for weekdays, and 4-6 weeks for weekends. The Mangusta 80 and Ferretti 94 often sell out early. For the best availability, consider a 4-hour morning slot (9:00-13:00) when the sea is calmest and the sun is less intense.
What is the cancellation policy for August charters?
We offer free cancellation up to 72 hours before departure, with a full refund. Within 72 hours, a 50% fee applies. If we cancel due to severe weather (rare in August), you get a 100% refund or a reschedule. Check your booking confirmation for full terms.
Are there any August events or regattas that affect boating?
The Starlite Festival runs from mid-July to early September, but it doesn't impact boating. The Marbella International Regatta is in September, so August is generally clear of major nautical events. However, Puerto Banús is busy — allow extra time for berthing and boarding.
