August vs. September: which month is better for travelling depending on the type of destination

Every year, the same battle repeats itself in the WhatsApp group: August has more atmosphere; September costs less; in August everything is open; in September everything feels better.

By the third voice note, nobody has booked anything and the flight price has gone up.

The uncomfortable answer is that neither month always wins.

The useful answer is different: some trips clearly improve when you move them a few weeks, while others lose precisely what made them worth it in the first place.

At aparca&go, we have compared price, climate, crowds and calendar so the decision does not depend only on the feelings.

First, the data that changes the debate

September is not low season.

It is a less extreme high season.

In 2025, Aena’s Spanish airports handled 33.3 million passengers in August and 30.4 million in September.

In other words, traffic only dropped by around 9%.

Changing month does not turn El Prat or Barajas into a spa: there are still lots of people, full flights and pressure on access roads and parking areas.

The difference is more noticeable at the destination.

According to the INE Hotel Occupancy Survey, overnight stays fall clearly when August ends.

That drop is not distributed equally: it is more visible in very family-oriented destinations, islands and coastal areas shaped by the school calendar; less so in large capitals, congress destinations or cities that hold events in September.

Traveller translation: September does not guarantee a bargain.

What it offers is more room to find one, especially when you can move dates, airport or destination.

The places where September beats August

The comparison starts to become useful when we stop pitting entire months against each other and start looking at specific trips.

September does not improve August by magic: it improves it when it preserves what you are travelling for —sea, climate, terraces, routes or heritage— and reduces what gets in the way —extreme heat, queues, impossible reservations and peak-demand prices—.

In other words: swapping August for September is worth it when the destination still offers practically the same trip, but with less friction.

These are the situations where that exchange usually works best.

1. The Greek islands: the same summer, with less fighting for a table

Santorini, Crete, Rhodes, Naxos or Corfu are the clearest example of a destination that does not stop feeling summery when August ends.

The official Greek tourism office itself recommends travelling between September and mid-October to avoid both the most intense heat and the most crowded season.

What really changes?

Not just the photo of a beach with a little more visible sand.

It also becomes easier to fit ferries into the plan, get a table without organising dinner like a military operation and walk through whitewashed villages without every street feeling like the exit of a concert.

The water keeps the heat accumulated during summer and tourism activity continues, especially during the first half of the month.

The safest window: from 5 to 20 September.

On smaller islands, it is worth checking ferry frequencies and business closing dates if the trip gets close to October.

2. Balearic Islands, Sicily and Sardinia: when you want coves, not a patience test

On the major Mediterranean islands, August and September can offer a visually similar trip, but a very different one logistically.

In September, beach days, road trips and outdoor dinners still make sense.

What usually decreases is the simultaneous pressure on accommodation, parking, coastal roads and restaurants.

Here, September especially improves multi-stop trips: exploring Menorca cove by cove, crossing Sicily by car or combining villages and beaches in Sardinia.

In August, a flexible route can turn into a sequence of “fully booked”, “not possible without a reservation” and “the car park is two kilometres away”.

In September, something very holiday-like returns: changing your mind.

The most balanced window: the second and third week of September.

For intense nightlife or club seasons, August keeps the advantage; for beach, gastronomy and road trips, September usually offers a gentler experience.

3. Seville, Cordoba, Granada or Athens: cities that get their pavements back

Some cities do not need fewer visitors to improve, but a few degrees less.

Visiting monumental heritage in August can mean organising the day around air conditioning: getting up early, disappearing at midday and going back out when the ground stops radiating heat.

In September, especially from the second week onwards, the trip once again allows for long walks and back-to-back plans.

The difference is not aesthetic, but about how you use your time.

If you can walk between neighbourhoods, sit on a terrace and visit a monument without turning every journey into an endurance test, you make better use of each day.

That makes September especially interesting for three- or four-night getaways, where losing half a day to the heat weighs heavily.

The recommended window: from 15 to 30 September.

Before booking, check congresses, fairs and local festivals: they can push demand up even after August has ended.

4. Camino de Santiago, Picos de Europa and the Pyrenees: less heat does not mean less trip

For walking, September is not a cheaper August: in many cases, it is a more suitable month.

Temperatures are usually milder and exposure to the heat of the central hours of the day is reduced, an important advantage when the plan is precisely to spend much of the day outdoors.

The official Spanish tourism portal points to September as a good time to walk the Camino de Santiago thanks to these more comfortable conditions.

The way you experience the destination also changes.

On popular routes, shelters, access points and villages handle peak demand in August.

September allows you to keep enough services and daylight hours without concentrating everyone at the same viewpoints at the same time.

The mountains, of course, do not sign contracts: you need to check the forecast and adapt the route.

The most reliable window: the first half of the month for high mountains; practically all of September for mid-mountain routes or Camino stages, always with equipment for rain and temperature changes.

5. Jerez, La Rioja and Barcelona: September does not just preserve plans, it adds new ones

Sometimes September improves August because the destination does not merely stay open: it starts a season of its own.

In Spain, September brings grape harvest festivals in areas such as Jerez and Logroño, as well as celebrations like La Mercè in Barcelona and other local fairs.

In other words, you do not have to choose between fewer people and fewer things to do.

This type of trip works well for those who want to combine gastronomy, culture and street life.

During the day there are visits, wineries or heritage; in the afternoon and evening, an agenda appears that does not depend on the classic summer festival model.

The key is to check the exact dates: a festival can justify the trip, but it can also fill up accommodation for that specific weekend.

The best strategy: travel during the week and leave one of the central days for the event.

That way you enjoy the atmosphere without necessarily paying peak festival prices for every night.

The places where August really does offer a better trip

August does not only win when there is a festival on the calendar.

It also wins in destinations where a few weeks change the wildlife you can see, the roads that remain open, the daylight hours available or the ease of travelling through remote areas.

In those cases, travelling in September does not make exactly the same trip cheaper: it gives you a different one.

Iceland, if you want puffins, the Highlands and a road trip with more margin

Iceland is probably the most important correction to the rule that “September always improves August”.

For a first trip around the island, August is usually more complete: temperatures are among the mildest of the year, roads are in better condition, days are still very long and the wildlife season is still active.

The decisive detail is the puffins.

In places such as Borgarfjörður Eystri, puffin-watching season runs from mid-April to early August.

Arriving in September means accepting that those colonies will already have left the cliffs.

The route also matters: the F-roads that allow access to the Highlands only open for a short period during summer, and elevated areas can start to be covered in snow from September.

Before deciding the route, it is worth checking official road conditions in Iceland.

If you want puffins, remote hiking, mountain roads and long days, August is the safer bet.

Svalbard, if you want to experience the midnight sun

In the Svalbard archipelago, August preserves an experience that September can no longer offer throughout the month: the midnight sun.

In Longyearbyen, the midnight sun in Svalbard does not end until approximately 23 August.

That makes it possible to sail, walk or photograph the Arctic landscape at hours that would be the middle of the night anywhere else.

From late August, the so-called golden autumn begins, with long sunsets and a different kind of light.

It can be beautiful, but it is a different trip.

For anyone dreaming of the disorienting feeling of looking at the clock at midnight and still seeing the sun, August wins without needing to add any festival.

The Canadian Rockies, if the goal is high-mountain routes

Banff, Yoho, Kootenay or Mount Revelstoke also require nuance when comparing August and September.

According to Parks Canada hiking conditions, July and August are the main months for backcountry hiking: many alpine passes are not snow-free until well into July and, when September arrives, temperatures drop and the chance of snowfall at altitude increases.

September can be magnificent for more accessible routes, autumn colours and less pressure in some spots.

But if the trip is built around high passes, remote campsites or scenic roads that depend on snowmelt, August offers a wider weather and operating window.

Here, paying a little more can mean having more routes available, not just sharing them with more people.

Southern Greenland, if you want the greenest and most accessible version

Greenland also changes quickly between the two months.

The official tourism office highlights August as the best time to visit Greenland if you want to find the south at its greenest and combine hiking between communities, farms, Norse ruins and boat transfers.

In September, many activities are still possible and the northern lights appear, but average temperatures drop and cold nights or snow in the mountains start to become part of the planning.

Again, there is no universally superior month.

September works better for those looking for Arctic autumn and dark skies; August for those who want to maximise hiking, sailing and logistical ease in a destination where “summer” is a much narrower window than in the Mediterranean.

And yes: some events still justify August

There are also trips whose date cannot be moved by a few weeks without completely changing the experience.

Anyone who wants to experience the major Edinburgh festivals, attend the Mérida International Classical Theatre Festival, see the Descent of the Sella or take part in the Tomatina will have to travel in August, because the event is not an addition to the destination: it is the main reason to visit.

In these cases, accepting higher prices and larger crowds can be worth it, as long as the date is booked in advance and transport is planned before availability starts to shrink.

One factor none of these profiles should ignore: the airport

There is one final trap: August and September can be very different in price, climate or crowds, but they share something not very appealing: full airports, queues, car parks at capacity and slower access roads than usual.

Because you can spend weeks deciding whether Iceland in August or Sicily in September works better for you, only to put all your planning to the test by driving around the terminal looking for somewhere to leave the car.

That does not sound like the best start to a holiday.

That is why, whenever you travel, it is also worth sorting out how you will get to the airport.

With aparca&go, you can book your parking in advance, find the best available price and remove one of the few parts of the trip that is really not worth improvising.

August or September, it does not matter: the stress can stay at home.

And remember, the best choice is not the month with the best reputation.

It is the one where the destination offers exactly the experience you are travelling for.
