The locals' season
Mallorca in September & October: the island at its best
The sea is at its warmest, the crowds are gone, the wine harvest is on and everything fun is still running. Here's exactly what shoulder season looks like — and how to make the most of it.
The short version: it's the locals' favourite season
Ask anyone who lives here and they'll tell you the same thing — the best six weeks of Mallorca's year start when the August crowds fly home. In September the sea is at its warmest of the entire year (it's been heating up all summer), the air drops from “melting” to “perfect”, restaurant tables reappear, and the island exhales. October keeps most of that going, at lower prices still.
What the weather actually does
September
Expect 27–29°C by day early in the month, easing to around 25°C by the end. The sea sits at 25–26°C — warmer than July — and daylight runs past 8pm. Occasional dramatic thunderstorms pass through and clear within hours; they're part of the show.
October
Days of 21–25°C, sea still 22–24°C and absolutely swimmable well into the month. You'll want a layer for the evening and a plan B for the odd rainy day, but most of the month is blue-sky beach weather that northern Europe would kill for in June.
What's still open and running
Everything that matters. Jet ski and boat tours run through October — with the bonus that morning slots stop selling out a week ahead. Private charters get easier to book and the sea is at its calmest. The hidden calas that are elbow-to-elbow in August go back to feeling secret. Beach clubs typically stay open to mid/late October; most close for winter after that.
What's actually better than summer
- Wine country comes alive. September is harvest in Binissalem and the island's bodegas — the tastings and vineyard visits are at their most atmospheric, and late September brings harvest festivals with grape-throwing battles that tourists mostly never hear about.
- The Tramuntana road trip stops being a queue. Sa Calobra's hairpins in August are a coach-dodging exercise; in October the west coast loop is the drive it was always meant to be.
- Hiking season opens. The cliff walks to coves like Es Caló des Màrmols shift from “heatstroke risk” to glorious.
- Prices soften. Flights and hotels drop noticeably after the first week of September, and again in October — often 30–50% below August.
Planning a September or October day
The formula from our day-planning guide works even better in shoulder season: one anchor on the water in the morning, a long shaded lunch, a mirador or bodega in the afternoon.

Questions we get asked
Is the sea warm enough to swim in Mallorca in October?
Yes — the Mediterranean holds its summer heat, so October sea temperatures of 22–24°C are warmer than a British summer beach ever gets. Most people swim comfortably to the end of the month.
Are boat trips and jet ski tours still running in September and October?
Yes, the main operators run right through October, and availability is far better than peak summer. Send your dates through the free planner and we'll confirm what's running in your week.
Is September cheaper than August in Mallorca?
Noticeably. Flights and accommodation typically drop 30–50% after the first week of September, and activities stop selling out days in advance.
What should I pack for Mallorca in October?
Summer clothes plus one warm layer for evenings, swimwear, and walking shoes if you plan to reach the hidden coves — it's prime hiking weather.
