Menorca in September offers an appealing combination of warm weather, a very warm Mediterranean Sea and a gradual reduction in the pressure of the main summer season. It can still feel unmistakably like summer, especially during the first half of the month, but September is also when Menorca begins its transition towards autumn.
For visitors, that creates both opportunities and a few uncertainties. You can still swim, spend full days at the beach, eat outside in the evening and enjoy many of the island’s summer activities, but there is a greater chance of rain and thunderstorms than in July or August. The first week of September can also remain busy, especially around Maó during the Festes de Gràcia, while the final part of the month generally feels noticeably calmer.
If you are considering Menorca in September 2026, the important question is not simply whether the weather is “good”. It is whether September suits the type of holiday you want.
Is September a Good Time to Visit Menorca?
Yes. September is one of the best months to visit Menorca if you want warm sea temperatures, beach weather and a less intense atmosphere than peak August.
Spain’s State Meteorological Agency, AEMET, records a long-term September average temperature of 22.6°C at Menorca Airport, with an average daily maximum of 26.2°C and an average minimum of 18.9°C. These are climate averages rather than a forecast for September 2026, but they provide a much more reliable guide than judging the month from an individual year’s weather.
September is not low season. The island is still active, beaches remain central to most holidays and many seasonal businesses continue operating. What changes is the rhythm. As the month progresses, there are generally fewer peak-summer pressures around car parks, restaurants and popular resort areas.
For couples, families with pre-school children, walkers who still want beach time and visitors who find August too hot or crowded, September can be perceived as attractive.

| Average daily minimum | 18.9°C |

Those figures explain September better than simply calling it a hot month. Daytime temperatures remain very comfortable for beaches and swimming, while evenings are usually mild enough for outdoor dining. At the same time, average rainfall rises substantially from August’s 20 mm to 61 mm in September, and AEMET records an average of 4.7 days with thunderstorms during the month.
That does not mean you should expect five ruined holiday days. A day recorded as having rainfall may still contain many dry or sunny hours, and Mediterranean thunderstorms can arrive and disappear quickly. It does mean that anyone visiting in September should have more weather flexibility than someone coming in July.
Can You Swim in Menorca in September?
Yes. September is an excellent month for swimming in Menorca, and the sea is often warmer than visitors expect.
The sea remains very warm in September. Official Balearic Government monitoring at Menorca stations including Port de Maó and Fornells has recorded water temperatures of around 24–25°C even towards the end of September in recent years.
The sea therefore loses heat much more slowly than the air as summer ends. Even if an evening feels cooler than August, the water can remain exceptionally comfortable.
Swimming conditions still depend on the individual beach. Wind, waves and currents can make one coast considerably less attractive than another on the same day. Jellyfish can also occasionally be carried towards certain beaches, so check the flags and lifeguard advice when you arrive. Our Jellyfish in Menorca guide explains how to check recent sightings and what the jellyfish warning flag means.
Does It Rain in Menorca in September?
September is wetter than June, July and August, so some rain should be considered normal rather than exceptional.
AEMET’s long-term average is 61 mm for the month, spread across approximately 5.4 days with at least 1 mm of rainfall. September also averages 4.7 thunderstorm days. By comparison, July averages only 3 mm of rainfall and August 20 mm.
The practical lesson is to watch the hourly forecast rather than a simple daily weather symbol. A thunderstorm predicted for part of the afternoon does not necessarily mean abandoning an entire beach day, while an organised weather system can occasionally produce a genuinely wet day.
If that happens, Menorca has far more options than many visitors realise. Museums, markets, wineries, farms, historic buildings, galleries, spas and restaurants all provide alternatives, which we cover separately in our guide to what to do in Menorca when it rains.
Is Menorca Crowded in September?
September normally feels less pressured than August, but describing the island as quiet throughout the month would be misleading.
The beginning of September is still part of the main summer travel period. Popular beaches can remain busy, restaurants may still require reservations and coastal resorts continue to have a distinctly summer atmosphere. Maó becomes especially lively around its major September fiesta.
The change becomes more noticeable as the month progresses. Families tied to European school holidays begin to disappear, the island becomes easier to move around and some of the extreme demand for the most famous beaches begins to ease.
This is one reason September works very well for visitors who want a beach holiday but do not need Menorca to be empty. You retain much of the summer experience while gaining progressively more space.
What Is Open in Menorca in September?
Most visitors should still find plenty open in September, particularly during the first and middle parts of the month.
Hotels, restaurants, shops, supermarkets, car-hire businesses and the main tourism services continue operating across the island. Maó and Ciutadella are working towns rather than purely seasonal resorts, so they remain active long after the summer holiday period ends.
The greater uncertainty concerns highly seasonal businesses. Beach bars, resort restaurants, water-sports operators, boat excursions and other summer-focused services can begin reducing hours or setting closing dates as the month progresses. There is no single island-wide date when Menorca “closes”.
If a certain restaurant, boat trip or activity is important to your holiday, check directly before travelling, especially during the final week of September. Never assume that an opening time displayed by an old travel article or directory is still current.
What’s On in Menorca in September 2026?
September is not simply a quieter beach month. It contains some important Menorcan fiestas, including one of the island’s major celebrations.
The Festes de la Mare de Déu de Gràcia in Maó have their principal days on 7 and 8 September. The celebrations include the traditional horse procession and jaleo, and Maó’s official fiesta history confirms that the patronal celebrations take place on these dates each year. The 2026 programme has already been presented, with events building in the days beforehand.
Further September festivities currently listed for 2026 include Sant Nicolau at El Toro on 11–13 September, the main Cala’n Porter jaleos on 19–20 September, and Es Caixers in Alaior on 25–27 September. Programmes and individual event timings can change, so visitors attending specifically for an event should verify the final local programme nearer the date.
If you are staying in or around Maó during the Festes de Gràcia, expect the centre to feel considerably busier than the phrase “September is quiet” might suggest.
Early September vs Late September in Menorca
Early and late September can feel like two slightly different versions of the island.
Early September is much closer to August. The sea is extremely warm, resort areas are lively and summer businesses are operating at or close to their normal seasonal rhythm. It is a strong choice if your priority is still very much a traditional beach holiday but you would prefer to avoid the peak weeks of August.
Late September feels more transitional. Beach days are still very possible and the sea remains warm, but evenings can feel cooler, weather becomes more important to daily planning and tourist numbers generally fall further. Some highly seasonal businesses may also begin reducing their operating schedules.
Neither is automatically better. Early September suits visitors wanting maximum summer atmosphere; later September suits people who value space, slower days and greater flexibility.
What Should You Pack for Menorca in September?
Pack primarily for summer, but not exclusively for summer.
Swimwear, light clothing, sunglasses, sun protection and a hat remain essential because the September sun can still be strong. Comfortable footwear is worthwhile if you intend to explore the Camí de Cavalls, archaeological sites or towns rather than spending every day at a resort.
Add a light jumper or jacket for evenings and a lightweight waterproof layer for unsettled weather. You do not need winter clothing, but relying entirely on shorts, sandals and beachwear provides less flexibility than it does in July.
It is also worth remembering that cloud does not eliminate UV exposure. September visitors can still burn quickly, so be mindful around midday or during long days on the water.
Is September Good for Families in Menorca?
September can be good for families travelling with babies, toddlers or pre-school children because daytime temperatures are generally less extreme than peak August while the sea remains warm.
The main limitation for families with older children is obvious: school terms have restarted in many countries. For those able to travel outside school holidays, however, September can offer an easier balance between beach conditions and the practicalities of moving around Menorca.
The reduced heat can also make mixed holidays more enjoyable. Archaeological sites, town visits and short walks are easier to combine with the beach than during an intense August afternoon.
Is Menorca Expensive in September?
September is no longer the absolute peak of the summer season, but it should not automatically be treated as a bargain month.
Prices depend heavily on the dates, accommodation type, flight market and where you stay. Early September can still command strong rates, particularly for high-quality villas and popular hotels. Later dates may offer better availability as demand falls, but there is no guarantee that a hotel, villa or flight will be substantially cheaper.
The best approach is to compare the actual total cost of the holiday rather than assuming that moving a trip from August to the first week of September will automatically transform the price.
Menorca in September: Quick Answers

Is the sea warm in Menorca in September?
Yes. The sea remains warm in September, with temperatures still around the mid-20s Celsius for much of the month and official monitoring showing approximately 24–25°C even towards late September in recent years.
Does it rain a lot in Menorca in September?

Are restaurants open in Menorca in September?
Yes, September is still part of Menorca’s tourism season and there is extensive choice. However, individual seasonal restaurants and beach businesses may begin changing hours or closing later in the month, so check anywhere you want to visit.
Is Menorca quiet in September?
It becomes progressively quieter after August, but early September can still be lively. Maó is very busy around the Festes de Gràcia on 7 and 8 September.
Is September better than August in Menorca?
It depends on what you value. August offers the strongest peak-summer atmosphere and generally more stable dry weather. September offers a similarly warm sea, comfortable temperatures and gradually fewer crowds, but with a greater chance of rain and thunderstorms.
Menorca in September: The Verdict
Menorca in September is one of the island’s strongest choices for visitors who still want a genuine Mediterranean beach holiday but do not need the intensity of peak August.
The statistics explain much of its appeal: average daytime highs above 26°C, a sea temperature around 25°C and 225 hours of sunshine across the month. The compromise is that rainfall and thunderstorms become more likely, compared with the exceptionally dry middle of summer.
The biggest mistake is treating all of September as identical. Early September still behaves much like summer, while late September begins to reveal Menorca’s quieter autumn character. Choose between them according to the holiday you actually want rather than simply searching for the hottest possible week.
