Mallorca in September: Why It's the Best Month for a Family Holiday

What if you were told that the best Mallorca holiday doesn't happen in July or August — but in September? Warmer sea temperatures, quieter beaches, lower prices, and an island that finally gets to breathe again after the high season rush. Sounds good? It absolutely is. Here's everything you need to know for your Mallorca holiday in September.

Why September Is Simply the Best Month on Mallorca

September has an almost legendary reputation among those in the know on Mallorca — and it's completely deserved. What makes this month so special?

• Warmest sea temperature of the year: The Mediterranean reaches its highest water temperature in September — around 25–26°C. It doesn't get much better for swimming and splashing. Every month of the year, with temperatures: 👉 Water Temperatures in Mallorca
• Pleasantly warm air temperature: 24–27°C during the day, a lovely 20–22°C at night — perfect for active days and relaxed evenings on the terrace
• Far fewer crowds: The school holidays are over and the peak-season masses have gone home. The beaches are yours again
• Golden light: The September light on Mallorca is simply unbeatable for photography — warm, soft, with just a hint of autumn in the air
• The island is yours: Restaurants take their time with you again, waiters are less rushed, and genuine Mallorcan life filters back through
• Lower prices: Accommodation, flights, and restaurants in September often cost 20–40% less than in August

Mallorca in September with Kids: Why It Really Works

For families with children, September in Mallorca is almost too good to be true. Here are the concrete advantages:

Quieter Beaches — Finally

In August, even Playa de Muro is so packed you can barely find a spot. In September, you have room to breathe. Children can run, dig, and play freely—without constantly having to watch out for other beachgoers. And as a parent, you won't lose sight of your little ones in the crowd.

The Heat Is More Manageable

37°C in August is exhausting for young children and babies. In September, the peak temperatures are 26–28°C — warm enough for a perfect beach day, but without the draining midsummer heat. The lunchtime nap battle in an overheated finca is a thing of the past.

Activities Beyond the Beach Become Fun Again

In August, so many things are a struggle: day trips end in traffic jams, attractions are rammed, restaurant bookings are near impossible to get. In September, the island opens up again — trips to the Cuevas del Drach, the Sóller Train, or through the Tramuntana villages become genuinely enjoyable again.

Other People's School Children Have Gone Home

Depending on your situation, a September holiday might still fall within the school holidays — or the first week or two of term might already be done, and a short post-summer break is perfectly feasible. Either way, other families' school-age children have already gone home.

September Weather in Mallorca: What to Actually Expect

No surprises, just the facts:

• Average temperature: 24–27°C during the day, 20–22°C at night
• Sea temperature: 25–26°C — the warmest water of the entire year
• Hours of sunshine: Around 8–9 hours per day
• Rainy days: On average 3–6 days per month — usually short, sharp showers, not days of non-stop rain
• Wind: The Tramuntana wind can pick up in September — sometimes creating waves at north-facing beaches, but no problem at sheltered south-facing spots

Our tip: Pack a light jacket for the evenings and a rain jacket for the occasional shower. Everything else stays pure summer.

Best Beaches in Mallorca in September

The great thing about September: almost every beach is good — but some have particular advantages in the autumn shoulder season.

Playa de Muro & Alcúdia Bay

The family classic remains brilliant in September. The shallow water is now at its warmest and the beach bar atmosphere is far more relaxed than in August. Perfect for children of all ages.

Es Trenc (South Coast)

In August, this famous natural beach with white sand and turquoise water is hopelessly overcrowded. In September it finally becomes what it was always meant to be: one of the most beautiful beaches in Europe. Head there early — parking is limited.

Cala Mondragó (Nature Reserve, Southeast)

One of the most beautiful sheltered coves on the island, set within a nature park. Ideal in September: crystal-clear water and the cove is accessible again without the long queues.

Cala Millor & Sa Coma

Wide, sandy, family-friendly and pleasantly quiet in September. Great restaurant options right along the beachfront — and the water is wonderful.

Playa de Palma

Ideal for a day trip from your finca or holiday apartment: easy to reach, wide sandy beach, plenty going on — and in September, finally relaxed again.

Best Days Out in Mallorca in September

September is the ideal month to actually explore the island — not just lie on the beach:

Cuevas del Drach — No More High-Season Queues

The famous Dragon Caves near Porto Cristo are one of the island's most popular attractions. In August you can queue for over an hour. In September it's far more relaxed — and the light show on the underground lake is breathtaking at any time of year.

The Sóller Train — The Island's Most Scenic Rail Adventure

The historic mountain railway from Palma to Sóller winds through the Tramuntana mountains and is an experience for children and adults alike. In September the temperatures are perfect for sitting in the open viewing carriages.

Exploring Palma

Mallorca's capital is at its most enjoyable in September: the cathedral La Seu, the old town, the harbour and the many small markets and cafés — all without the stifling August heat and the tourist onslaught.

The Mallorca Grape Harvest: September Is Vendimia Season

A genuinely special insider experience: September is when the grapes are harvested on Mallorca. Several vineyards in the Binissalem area offer tours and tastings — a highlight for the adults and at the very least fascinating for the children.

Sa Dragonera Nature Reserve

The small island off Mallorca's southwest coast is reachable by ferry and makes a beautiful day trip. In September the ferries are still running and visitor numbers are manageable.

Accommodation in September: Why Booking Early Still Pays Off

Despite all the advantages of the shoulder season: September in Mallorca is no longer a secret. According to tour operators, airlines and accommodation providers, September frequently surpasses previous months in popularity. That means: good fincas and holiday homes are still in demand in September.

Recommendation: For the first half of September (1st–15th) book well in advance — there's still some high-season momentum. The second half of September is quieter and cheaper. Those with flexibility travel from the 15th September onwards for significantly better rates.

What to Pack for Mallorca in September

The September packing list is lighter than you'd think:

• Summer clothes are still essential — it's genuinely warm
• A light jacket or cardigan for evenings and the odd shower
• Sunscreen SPF 30 and SPF 50 — the sun is still strong
• Swimwear — the sea beckons every day
• Walking shoes — ideal for Tramuntana excursions at comfortable temperatures
