Most of us arrived with a rule of thumb about September, inherited from whoever showed us around in the first month. July and August belong to the visitors. The children go back mid-September, the crowds thin, and the Costa is handed back to the people who live on it. Restaurants take bookings again. The beach has parking. The inland towns go quiet.
Half of that rule is still exactly true, and it is the half you can check in a document. Schools in Málaga province went back on 10 September 2026 for infant and primary years and 15 September for secondary. The other half, the part about the Costa emptying, is where the rule has drifted, and the drift is what the figures below can and cannot show. It shows up in four separate measurements that mostly do not agree with each other, which is its own problem and part of what this guide is for. What follows is what each instrument actually measures, what has changed at the edges of the temporada alta — high season. Then the public holidays that close things between mid-September and November, and which of those things are worth booking rather than walking into.

The part of the rule that still holds
The school half is firm, and it is worth having the exact dates because they are the thing people actually plan around. The Junta’s Málaga delegation set the 2026-27 calendar by resolution on 20 May 2026. Second-cycle infant, primary and special education started on Thursday 10 September 2026. Tuesday 15 September was the start for secondary and vocational grades, including bachillerato — sixth form. Official language schools start on Monday 21 September.
So from the middle of September the Spanish-curriculum schools are back. That much is real. The second half of September is the half with school in session; how much easier it is for a resident is not something these figures measure.
Four instruments, and why their numbers do not match
This is what makes the season hard to read. The occupancy headlines we checked this month each quote one of these four, and most do not say which.
Aehcos is the province’s hotel employers’ association. It publishes occupancy figures for its associated establishments; it has not published the denominator or response base behind them in the material we have seen. Its most recent release, dated 1 September 2026, put August 2026 at 92.85% closed, and forecast 88.58% for September 2026 and 83.07% for October. Two of those three are forecasts.
INE, the national statistics institute, runs four surveys of registered establishments in the province: hotels, tourist apartments, campsites and rural accommodation. Private homes let on platforms are outside them. Turismo y Planificación Costa del Sol compiles those figures into a monthly bulletin. On that instrument, hotel bed-place occupancy in Málaga province in September 2025 was 69.8%, down 1.9 points on the year before, and room occupancy 84.0%.
Aehcos reported 90.97% for its associated establishments for the same month. The two sit 21 points apart, and the association has not published the denominator that would let anyone compare them like for like. The practical consequence is that a sentence beginning “hotel occupancy on the Costa del Sol was” is meaningless without the instrument attached, and most of the ones you will read do not attach it.
AVVAPRO is the Andalusian association of tourist homes and flats. It reports booking pace and prices for its members, and its method is not published; its September figures are booking pace at a survey date rather than a closed month. Ruralidays is a commercial letting platform reporting on its own portfolio, described as more than 2,800 rural properties. Both are useful. Neither is a province-level measurement, and both are routinely quoted as though they were.
What the official count says, on its current revision
The official figures come from INE’s four accommodation surveys, which Turismo Costa del Sol compiles into a monthly bulletin. INE revised its 2025 series on 11 and 14 September 2026, so the numbers below are the current ones, not the bulletin’s original provisional set.
The figure the bulletin leads on is pernoctaciones — overnight stays. Across the four surveyed categories, September 2025 came to 3,108,383 of them, against 3,090,645 in September 2024, a rise of 0.6%. Arrivals rose 3.0% to 806,656. It was widely reported as September passing three million, which is true.
The first eight months of 2025 had run 273,691 nights behind the same months of 2024. September added 17,738, about 6.5% of that gap, and January to September closed down 255,953, or 1.0%. The month did not rescue the year. It stopped the year getting worse.
The interesting number is a different one. Arrivals rose 3.0% while overnight stays rose 0.6%, and the average hotel stay fell to 3.67 nights from 3.80. More arrivals were counted, and the average hotel stay fell. Among the coastal provinces, Málaga ranked third on arrivals and fifth on overnight stays.
This year is running ahead of that. January to July 2026 came to about 18.4 million nights across the four categories, up 6.3%, and July 2026 alone was up 7.5%. August’s hotel data publishes on 22 September and September’s in late October, so no September 2026 actual exists yet.
Who is actually here in late September
Shorter average stays and more arrivals are the measured part. What a visitor on three or four nights does with the days is not measured by any of these sources.
The origin mix is where a single month misleads most. On INE’s current figures, arrivals by residents of Spain rose 5.0% that month and arrivals by residents abroad rose 2.1%, so both halves grew. The bulletin’s country-by-country table, which showed most named markets falling, cannot be reconciled with those totals without the compiler’s definitions, so single-month country movements are not a safe basis for a claim about any one market.
Ruralidays reports a rising German share in its own rural portfolio for autumn 2026 (26.95% of its September-to-November bookings, per La Opinión de Málaga on 10 September), and that gets repeated as a claim about Málaga. It is one platform’s book. The province-wide official series carries no such finding, and a platform’s portfolio and a province are not the same population.
On inland, the same caution applies twice over. Ruralidays names Torrox, Nerja, Frigiliana and Cómpeta as the most sought-after towns in its own book, and forecasts 75% occupancy for its Málaga properties. INE’s own rural figure for September 2025 was 27.1% bed occupancy across registered rural establishments in the province. A platform’s forecast for its own houses and a survey of registered establishments are different populations in different years; do not set one against the other. What survives is only that those four towns are the ones this platform reports as most in demand.
The most misread behavioural figure is eDreams’ booking data, published in August 2026: of bookings or searches made from Spain on its platform between 1 May and 20 July for September travel, 85% were at least 61 days ahead and 57% of trips ran three to six days. That is a measurement of how people booking from Spain in early summer planned September. It says nothing about foreign visitors’ lead times, about restaurant tables, or about who is competing for a casa rural.
The dates that close things between mid-September and November
This is the concrete part. Two layers of public holiday apply, and the second one catches people out every year because it differs from town to town.
Andalucía-wide, set by Decreto 101/2025:
- No regional holiday at all between 15 August and 12 October. There is no Andalucía-wide holiday in the second half of September; local days still apply.
- Monday 12 October 2026, Fiesta Nacional de España. It falls on a Monday, so 10 to 12 October is a three-day weekend.
- Monday 2 November 2026, Todos los Santos. The holiday itself is 1 November, which falls on a Sunday in 2026 and moves to the Monday. So 31 October to 2 November is a three-day weekend as well.
Those two long weekends sit inside the period residents think of as quiet.
Then your own town’s two local days. Every municipality in Andalucía sets two of its own, called fiestas locales — local public holidays. They are legally days off. For 2026, the ones falling in this window on the Costa are:
- Istán, Monday 28 and Tuesday 29 September
- Torremolinos, Tuesday 29 September
- Torrox and Vélez-Málaga, Friday 2 October
- Benahavís and Fuengirola, Wednesday 7 October
- Ojén, Thursday 8 and Friday 9 October
- Mijas, Thursday 15 October
- Marbella, Monday 19 October, which gives Marbella a second three-day weekend a week after the national one
Málaga city’s two fell on 19 August and 8 September, both already gone. Benalmádena, Estepona, Nerja, Frigiliana and Cómpeta have none left in 2026. The point is not the list. Your town hall closes on your own town’s days and not on your neighbour’s, and that includes the counter you would queue at for the padrón — town-hall registration. Torrox closing on a Friday in October is the difference between a wasted drive and a useful one.
What to book rather than walk into
- Check your own town’s holiday date before booking anything at the town hall. The holiday closes that town’s offices on that day, not the week, and the local dates are not in the uniform Andalucía-wide holiday list.
- Book restaurants for the two long weekends. 10 to 12 October and 31 October to 2 November are three-day weekends for anyone on a Monday-to-Friday week. Nothing here measures how full the tables will be; a booking is a precaution.
- Put inland day trips on dates. Torrox, Nerja, Frigiliana and Cómpeta are the four towns Ruralidays reports as most sought-after in its own portfolio this month. Torrox’s offices are shut for its local holiday on Friday 2 October.
- October carries lower forecasts, not a promise of quiet. Aehcos forecasts 83.07% for October against 88.58% for September for its associated establishments; Ruralidays says about 64% for its own houses. Neither says anything about appointment availability, and San Diego Comic-Con Málaga fills FYCMA from 1 to 4 October.
- November is not covered by any figure here. The Aehcos forecast series stops at October, and the next regional holidays after 12 October are 2 November and then 7 and 8 December. Treat anything said about late autumn, including in this guide, as unmeasured.
If you let a property
AVVAPRO, in a 29 August report, put Málaga city bookings for September 2026 ahead of the 2025 pace at the same survey date, and the province’s average September price at EUR 181.50 against EUR 165.80 the year before, up 9.5%. Its projection for the province as a whole was 47.6%.
Those are two different measures, a city booking pace and a provincial price, and neither says anything about a particular street or town. Repricing a Benalmádena flat on a Málaga city figure is the obvious way to get this wrong, and setting a September booking-pace figure against an August figure is the other one, because the first is bookings taken by a survey date and the second is a different measurement of a different month.
What the reports say is that the letting associations are selling September as a strategic month. That assumes the letting is registered; for most short lets that is a vivienda con fines turísticos — registered tourist home, though it is not the only lawful class. The licence side is covered separately in our guide to the tourist rental licence in Andalucía.
What this guide does not tell you
It does not tell you why. One explanation offered is that extreme-heat days are pushing demand out of July and August into the edges of the season. It may be right. It does not appear in any of the sources above, none of which tests it, so it is not asserted here.
It does not give you a single occupancy number for the Costa del Sol, because there is not one. It gives you four measurements of different populations and tells you which is which.
The 2025 figures above are INE’s current revision of 11 and 14 September 2026; the bulletin’s original set was provisional and has been superseded. The Aehcos September and October 2026 figures are forecasts, not closes, and a September close will supersede them. AVVAPRO and Ruralidays describe their own members and their own portfolios.
And it makes no claim about appointment waiting times, which vary by office and by town in ways none of the tourism sources here captures. The holiday closures above are the part that is documented.
The five-minute version
- The school half of the old rule is intact. Málaga province schools went back on 10 September 2026 for primary and 15 September for secondary, by the Junta delegation’s resolution of 20 May 2026.
- The emptying half has drifted. September 2025 overnight stays across the four surveyed categories were 3,108,383 against 3,090,645, a rise of 0.6% on INE’s current revision. Arrivals rose 3.0% while the average hotel stay fell to 3.67 nights. More arrivals, shorter average stays. January to July 2026 is up 6.3%.
- September did not rescue 2025. The first eight months were down 273,691 overnight stays and September gave back 17,738, about 6.5% of it.
- Never take an occupancy figure without its instrument. For September 2025, Aehcos reported 90.97% for its associated establishments and INE 69.8% bed-place occupancy (84.0% by rooms). Twenty-one points apart, and not like for like.
- The autumn dates that close things: Monday 12 October and Monday 2 November region-wide, plus your own town’s two local days. On the Costa in this window: Torremolinos 29 September, Torrox and Vélez-Málaga 2 October, Fuengirola 7 October, Mijas 15 October, Marbella 19 October.
- The move is to book what matters, particularly restaurants on the two long weekends and inland day trips on fixed dates, and to check your own town’s holiday date before a town-hall visit. That is a precaution, not a measured shortage.
