Mallorca in September (2026): Warm Sea, Fewer Crowds, and the Wine Harvest

Temperature and Daylight

Mallorca September weather is warm and pleasant, summer easing into early autumn. Mallorca September temperatures in Palma typically reach around 27°C in the afternoon, hot early in the month and softening toward the end, while nights are comfortable at around 17°C. Days are noticeably shorter than midsummer, with sunset near 8:00 PM, but you still get plenty of warm, usable daylight.

Rain Pattern

September sees the first real autumn rains, averaging about five rainy days, more than the dry peak summer. What typically happens is long warm, sunny spells broken by the occasional short, sometimes heavy, thunderstorm, especially in the second half of the month. It rarely spoils a trip, but it is worth keeping an indoor option like the cathedral, a winery visit, or the Caves of Drach in reserve.

Sea and Outdoor Conditions

The Mallorca September sea temperature is around 25°C, still warm after the long summer and one of the year's best months for swimming, since the water holds its heat even as the air cools. The coast and the boat trips are all running. On land, the easing heat makes the hiking and the wine-country drives far more comfortable than in August, especially late in the month. Pack for warm days and mild evenings, with beachwear and a light layer, plus a packable waterproof for the odd storm. In our view September lets you pack for the beach and the hills at once.

September is a month of steady relief: crowds and prices fall away through the month as the European schools go back, while the weather stays warm. Early September still feels like summer; by late September it is calmer and much better value.

To put September in context, here is how Mallorca's three big trip variables, temperature, crowds, and hotel prices, move across the year. September sits at the warm, easing, better-value start of autumn, highlighted in each chart below.

ℹ️ Charts are based on typical Mallorca climate normals and the Palma 4-star mid-range hotel pricing our team tracks. Actual rates vary year to year and by booking lead time. September prices fall steadily through the month from the summer peak.

If you are weighing September against the months either side of it, this is the quick version. The table covers the two months before and after September so you can see how the early-autumn window stacks up.

The short read: September is the great unwind from peak summer. It keeps August's warm sea but sheds its crowds and prices week by week, which is why so many regulars prefer it. October then cools further and quietens more, and from November the island slides toward its low season. If you want warm-sea swimming with real value, September, especially the second half, is hard to beat. For the month just before, see our Mallorca in August guide, and for the full year-round picture, our guide to the best things to do in Mallorca.

September's calendar is led by the grape harvest, with the beach season still in full flow and the island shifting gently into autumn.

The Wine Harvest and Festa des Vermar

September is harvest time in Mallorca's vineyards, in the Binissalem and Pla i Llevant wine regions, and the celebrations peak with the Festa des Vermar in Binissalem in late September. The town fills with grape-themed events, a famous grape fight, tastings, processions, and music, a joyful, very local festival. In our view it is the standout reason to choose late September, and the wineries are at their most atmospheric with the harvest under way.

The Beach Season Holds On

Despite the harvest in the hills, the coast is still firmly in summer mode: the sea is warm, the beaches and boat trips are running, and the resorts are open. You can swim in the morning and visit a winery in the afternoon, a combination that sums up what makes September special.

Diada de Mallorca

September 12 is the Diada de Mallorca, the island's official day, marked with civic events and some cultural activities in Palma. It is a low-key occasion compared with the summer fiestas, but it adds a little local color early in the month.

September has very few real downsides, which is why it is such a favorite. The things to be aware of are the first autumn rains, the busier, pricier start of the month, and the shortening days.

The First Autumn Rains

September brings the season's first proper rain, with the occasional short, heavy thunderstorm, especially in the second half of the month. Most people don't realize these storms are usually brief, clearing to warm sunshine, so they rarely wreck a trip; the fix is simply to keep an indoor option in reserve and check the forecast, particularly late in the month.

A Busier, Pricier Start

The first week of September still carries the August feel, with higher crowds and prices, before both fall away once the schools go back. If value and space are your priority, aim for the middle or end of the month rather than the first few days.

Shortening Days and Cooling Water

The days are noticeably shorter than midsummer, with sunset around 8:00 PM, and while the sea stays warm, the air cools through the month. We think the tradeoff is firmly in September's favor: a little more weather variability and shorter days in exchange for a warm sea, an open island, and far better value than the peak.

What We'd Prioritize in September

September is the month to have it both ways. The sea is still warm, so keep the coast central, a catamaran cruise, a snorkeling or kayak trip, or a day at a now-quieter cove. But it is also harvest time, so pair the beach with a winery visit while the vines are being picked, which is one of the most enjoyable things to do on the island all year. We'd give this combination the edge for travelers who want warm-sea summer and a taste of the island's culture without the August crush.

As the heat eases, the hiking, the Palma sightseeing, and the scenic drives all become more comfortable too, especially late in the month. Keep an eye on the forecast for the odd autumn storm and have the cathedral or the Caves of Drach in reserve, but for the most part September lets you do almost everything in near-ideal conditions. For the full menu across the year, see our guide to the best things to do in Mallorca.

Beyond the bookable tours, a handful of experiences suit a warm September day:

• Festa des Vermar in Binissalem: Time a late-September visit around the wine-harvest festival, with its grape fight, tastings, and processions in the heart of the wine country.
• Cove-hopping in quieter waters: The smaller calas are warm and far less crowded than in August, ideal for a relaxed swim and a snorkel.
• Cap de Formentor drive: The northern headland is spectacular and noticeably quieter now, a classic late-summer drive.
• Sóller train, tram, and port: The scenic ride and a seafront lunch are lovely in the warm, calmer September weather.
• Tramuntana hike as it cools: Late September is comfortable again for the Valldemossa-to-Deià path or the Barranc de Biniaraix.
• Markets in the wine towns: The weekly markets in Binissalem, Sineu, and the Pla are full of late-summer and early-autumn produce.
• Sunset and dinner outdoors: With sunset around 8:00 PM, the warm evenings are still made for terraces and late meals.

ℹ️ Tip: September can bring the occasional heavy thunderstorm, usually short. Check the forecast, especially late in the month, and keep a flexible, indoor-friendly plan in reserve.

September is an easy month to get around, with the full seasonal network still running but the peak-summer congestion easing. Here is how the airport, transfers, and driving look.

Palma Airport in September

Palma de Mallorca Airport (PMI) is still busy early in September but eases through the month as the summer season winds down, so it is generally smoother than July and August, especially later on.

Airport Transfers

The A1 airport bus runs frequently and reaches central Palma in about 15 minutes for a few euros. A taxi to the city is roughly €25. Resort transfer shuttles are still running for the season, with the queues shorter than at the peak.

Car Rental and Driving

Car rental prices ease through September as demand falls, so it is better value than the peak and still gives easy access to the coves, the wine country, and the mountains. The roads and beach parking are far less congested than in August, especially from mid-month, making September one of the more relaxed months to drive.

Public Transport

The island's TIB buses and the Sóller train run full summer timetables early in the month, easing later. For a city or coastal-town trip you may not need a car, but for the wineries, the coves, and the hills a rental is still the most flexible option, and cheaper than in peak season.

With the whole island still open and the crowds easing, September gives you the full choice of bases at better value than the peak. The coast still shines, while Palma and the wine country are strong options.

Best Bases

• The coast (Alcúdia, the southeast coves, Pollença, Port de Sóller): The sea is still warm, so a coastal base keeps you on the beach and in the water, now with quieter sands and lower prices than August.
• Palma: A great all-rounder for city, culture, and nightlife, with beaches close by, and the easing heat makes the old-town days far more comfortable.
• Wine country and the Pla (Binissalem and around): For a harvest-season trip, basing yourself near the vineyards puts you among the wineries and the Festa des Vermar, with the coast a short drive away.

Booking Note

• Early September still books up: The first week carries summer demand, so reserve ahead for it; mid-to-late September is easier and better value, though the popular coastal spots still fill at weekends.

If you have booked September holidays in Mallorca, the coast is still the natural choice for beach time, Palma suits a city-and-sea mix, and the wine country is a lovely harvest-season alternative.

Packing for Mallorca in September is warm-summer with a nod to autumn: hot-to-warm days, mild evenings, and the chance of a passing storm. Pack light, with a layer and a waterproof.

• Summer daywear: Light, breathable clothes for warm 27°C days, hotter early in the month.
• Beach kit: Swimwear, a towel, and sandals; the sea is still warm and the beach season is on.
• A light layer for evenings: Evenings cool to around 17°C, so a light sweater or jacket is handy after dark.
• A packable waterproof: September brings the first autumn showers, so a rain jacket or compact umbrella is worth carrying, especially late month.
• Good walking shoes: The easing heat makes hiking comfortable again, so bring proper footwear for the trails.
• Sun protection: Sun cream, sunglasses, and a hat; the September sun is still strong, particularly early in the month.
• A daypack: For the beach, water, sun kit, or layers and a waterproof on a hike or a wine-country day.

Yes, September is one of the very best months to visit Mallorca, and many regulars rate it the smartest of all. You get warm 27°C days, a sea still warm at around 25°C, the full beach season, and the grape harvest, all with crowds and prices falling away from the summer peak as the schools go back. The honest catches are a busier, pricier first week, the first autumn rains, and shorter days.

Our experience: If we had to name the single best-value month for a warm-sea trip, it would be late September. You still swim, sail, and sunbathe, but with autumn space, lower prices, and the wine harvest as a bonus. Come now, especially from mid-month, for summer conditions without the summer crush; only the very first days still feel like the peak.

In short: choose September, especially the second half, for a warm sea, an open island, and excellent value, with the wine harvest on top. For the month just before, see our Mallorca in August guide, and for how the rest of the year compares, our guide to the best things to do in Mallorca.

• Travel mid-to-late month for value: The first week still carries summer crowds and prices; from mid-September both fall away while the sea stays warm.
• Pair the beach with the wine harvest: Swim in the morning and visit a winery in the afternoon, with the Festa des Vermar in Binissalem the highlight late in the month.
• Pack a light waterproof: September brings the first autumn storms, usually short, so carry a rain layer and keep an indoor option in reserve.
• Make the most of the easing heat: The hiking, the Palma sightseeing, and the scenic drives are all comfortable again, especially late in the month.
• The sea is still warm: Do not write off swimming; at around 25°C the water holds its summer heat well into the month.
• Watch the forecast late month: The heaviest storms tend to come in the second half, so keep your plans flexible then.
• Enjoy the quieter coves: The smaller beaches are far calmer than in August, so seek them out for a relaxed swim.
