September is Europe’s best-kept travel secret — and the best places to travel in September 2027 prove it. The sea is at its warmest after a whole summer of sun, the August crowds have flown home, hotel rates drop 30–40% on the Greek islands and the Adriatic coast, and the weather is still warm enough for dinner outside. If you can only take one trip in 2027, take it in September. This guide covers 15 warm, cheap, crowd-free destinations, real daily budgets, and exactly when to book.
Why September 2027 Is the Smartest Month to Travel
September sits in the sweet spot between summer’s heat and autumn’s chill, and the numbers back it up. Once schools reopen in early September, Mediterranean islands and Adriatic resorts cut prices sharply — hotel rates on the Greek islands and the Croatian coast typically fall 30–40% from August peaks, with drops of up to 50% in places like Dubrovnik and Hvar. The sea, meanwhile, stays warm: the Mediterranean off Antalya holds around 27–28°C, and swimming in southern Europe is often more comfortable in September than in the peak-summer heat.
For US, UK, Canadian and Australian travelers, September 2027 also lines up perfectly with the booking calendar. Flights and hotels for shoulder season are best booked 3–6 months ahead — meaning the smart window is March to June 2027 — and the Black Friday and Travel Tuesday sales (27 November to 1 December 2026) are the cheapest moment to lock in fares. Book now, travel when the crowds are gone.
1. Santorini, Greece — Golden Hour Without the Queues
Santorini in September is the island at its best. The caldera sunsets are just as spectacular, the whitewashed lanes of Oia are walkable again, and hotel prices fall 30–40% once the August rush ends. The sea stays warm into early October, ferries still run at full frequency, and a sunset dinner in Oia no longer needs a reservation made weeks ahead. Budget: €70–110 per day mid-range, or €45–60 staying in Karterados or Perissa instead of Oia. For a cheaper Greek island with the same blue-and-white magic, read our guide to places like Santorini but cheaper.
2. Crete, Greece — Warm Water, Slow Days
Crete is the Greek island that rewards a slow September. The south coast beaches around Elafonissi and Balos are still swimmable, the mountain villages are harvesting olives and grapes, and tavernas serve the summer’s best produce at local prices. Base yourself in Chania or Rethymno — both are cheaper and more atmospheric than the resort strips — and rent a car for €25–35 a day to explore the gorges and hidden coves. Budget: €50–75 per day. Crete pairs perfectly with our cheapest cities in Europe guide if you’re continuing on to Athens.
3. Dubrovnik and Split, Croatia — The Adriatic After the Rush
September may be Split’s best month: warm water, full ferry service to Hvar and Brač, and Diocletian’s Palace without the rolling suitcases. Dubrovnik’s city walls are walkable without the cruise-ship crush, and prices on the coast drop up to 50% from August. The Adriatic stays swimmable into late September, and the islands are at their most relaxed. Budget: €60–90 per day, less if you stay in Split’s old town guesthouses or take the bus to the quieter Makarska Riviera.
4. Mallorca, Spain — Beaches and Mountain Roads
Mallorca in September keeps the warm sea and the long evenings but loses the package-holiday crowds. The Tramuntana mountain drives are glorious in the soft autumn light, the beach coves around Cala d’Or and Cala Mondragó are quiet again, and Palma’s old town is made for slow evenings. Skyscanner’s Travel Trends 2027 data shows Spanish destinations among the biggest fare drops of the year — Bilbao’s flights are down 66% — and the Balearics benefit from the same shoulder-season pricing. Budget: €65–95 per day.
5. The Algarve, Portugal — Europe’s Cheapest Warm Coast
The Algarve stays warm well into October, and September is when it becomes a bargain. Beach towns like Lagos and Tavira drop their prices, the sea is still around 22–23°C, and the cliff walks between Praia da Marinha and Benagil are at their most photogenic. Portugal’s interior is even cheaper, and Lisbon — covered in our Lisbon on a budget guide — makes the perfect two-city add-on. Budget: €55–80 per day, with dorms from €18 and set lunches around €9.
6. Tuscany, Italy — The Grape Harvest
September is harvest month in Tuscany, and the region turns gold. Vineyards around Chianti and the Val d’Orcia are picking grapes, village festivals celebrate the vendemmia, and the light turns the soft, mellow glow that photographers travel for. Stay in an agriturismo outside Siena or San Gimignano — rooms run €50–80 a night in September, half the summer rate — and eat where the harvest workers eat. Budget: €75–110 per day. For Italy’s quieter corners, see our secret places in Italy with no crowds.
7. Provence, France — Lavender’s Second Act
Provence in September trades the lavender crowds for the wine harvest. The Luberon villages — Gordes, Roussillon, Lourmarin — are quiet enough to enjoy properly, the markets overflow with figs, melons and goat cheese, and the light is the same golden light that drew Van Gogh and Cézanne. Base in Avignon or Aix-en-Provence and take the bus to the hilltop villages. Budget: €80–120 per day, or €60–80 staying in village gîtes and cooking from the markets.
8. Lisbon, Portugal — Hills Without the Heat
Lisbon’s steep hills are far more pleasant to climb in September than in the August heat, and the city keeps its warm, bright days long after summer ends. Day trips to Sintra and the coast at Cascais are easy, the trams are less packed, and the €9 set lunches are still on every menu. September is also when Lisbon’s festival season winds down gracefully — expect smaller crowds at the viewpoints and better-value rooms. Budget: €65–85 per day. Full costs and free things are in our Lisbon on a budget 2027 guide.
9. Barcelona, Spain — The City After the Peak
Barcelona in September still has beach weather, but the Ramblas are breathable again and the Sagrada Família queues shrink. The city’s festival season peaks with La Mercè (around 24 September), a four-day street party with fireworks, castellers and free concerts — one of Europe’s best free festivals. Book Gaudí sights in advance even in September, and stay in Gràcia or Poble-sec for local prices. Budget: €70–100 per day.
10. Rome, Italy — Comfortable Walking Weather
Rome in September is the city at walking temperature: warm days, cooler evenings, and the Forum and Vatican without the July furnace. Book Colosseum and Vatican time slots in advance even out of season, then spend your evenings in Trastevere, where the trattorias spill onto the piazzas. September is also when Rome’s hotel rates start to soften after the summer peak. Budget: €75–110 per day, or €55–75 with a hostel bed and market meals.
11. Amalfi Coast, Italy — The Coast Comes Back to Itself
The Amalfi Coast in September is the version locals love: the sea is warm, the lemon groves are heavy with fruit, and the buses between Positano, Amalfi and Ravello are no longer sardine cans. Prices on the coast stay high — this is the one destination on this list where September is a crowd fix, not a price fix — but staying in Salerno or Sorrento and day-tripping cuts the bill by a third. Budget: €90–130 per day from Sorrento, €70–100 from Salerno. If the Amalfi prices still sting, our Santorini alternatives guide shows the same coast for half the money.
12. Antalya, Turkey — 27°C Sea, Half the Price
Antalya’s Mediterranean holds around 27–28°C in September, and the resort coast — with its Roman ruins, turquoise bays and old-town kaleiçi — becomes one of the cheapest warm escapes in Europe. Turkey remains one of 2027’s best-value destinations at roughly $25–45 a day for budget travelers, and the lira’s weakness keeps eating, transport and stays cheap for US, UK and EU visitors. Budget: $35–55 per day. Turkey also features in our cheapest places to travel in Asia roundup.
13. Kotor, Montenegro — The Fjord Without the Cruise Ships
Kotor’s bay is one of Europe’s most dramatic settings, and September strips away the cruise-ship crowds that choke the old town in summer. The water stays clear and warm, the climb to the fortress above the bay is bearable in the cooler air, and the coastal road to Budva is a drive worth taking slowly. Montenegro outside the Kotor coast runs about $25–40 a day, making it one of the cheapest Adriatic options. Budget: €45–70 per day. Kotor pairs naturally with our Albania travel guide — the border is an hour away.
14. Marrakech, Morocco — The Heat Finally Breaks
Marrakech in September finally sheds its exhausting summer heat, and the city becomes walkable again. The medina’s souks, the Jardin Majorelle and the rooftop cafés of the old town are at their best in the warm evenings, and September is the perfect launchpad for the Atlas Mountains or the Agafay desert. Morocco is one of the cheapest winter-sun countries for 2027 at roughly $25–35 a day, and our full Morocco travel guide 2027 covers costs, itineraries and the best places in detail. Budget: $30–50 per day.
15. Bali, Indonesia — Dry Season’s Last Weeks
September is the tail end of Bali’s dry season: sunny days, low humidity, and the island’s greenest rice terraces of the year. The Australian school-holiday crowds have gone, Ubud’s cafes and Canggu’s beaches are relaxed, and the island’s famous $30-a-day budget still holds — scooter rental, warung meals and a private room for under $20. September is also Bali’s best surfing month on the Bukit Peninsula. Budget: $25–40 per day. Our Bali on a budget 2027 guide breaks down 10 things to do for under $30 a day.
September 2027: Daily Budgets at a Glance
- Cheapest (€30–55/day): Antalya, Kotor, Marrakech, Bali, Crete
- Mid-range (€55–85/day): Algarve, Lisbon, Santorini, Mallorca, Split, Tuscany

When to Book Your September 2027 Trip
The booking window matters as much as the destination. For shoulder-season trips, travel experts recommend booking 3–6 months ahead — so March to June 2027 is the prime window for September fares and hotels. But the first chance to save comes much sooner: the Black Friday and Travel Tuesday sales from 27 November to 1 December 2026 are the year’s deepest discount window, with Hopper reporting that Travel Tuesday 2025 drove roughly three times as many bookings as Black Friday. Set fare alerts now, compare any sale price against the last 30 days of fares (not the inflated list price), and book the flight when the price is right — hotel rates on the islands only get cheaper as September approaches, so there’s no rush on rooms.
Best Places to Travel in September 2027 FAQs
Is September a good month to travel to Europe?
Yes — for most travelers, September is the best month of all. May, June and September offer the best mix of warm weather, long days and manageable crowds, and September adds the warmest sea of the year plus prices 30–40% below August on the Mediterranean islands and the Adriatic coast.
Where is warm in September in Europe?
Southern Europe stays warmest: the Greek islands, the Algarve, the Amalfi Coast, the Turkish Riviera around Antalya (sea around 27–28°C) and the Balearics. Lisbon, Seville and the Greek islands often stay warm into October, while Paris and Amsterdam cool down sooner.
Is September cheaper than August for travel?
Yes, significantly. Once schools reopen, hotel rates on the Greek islands and the Croatian coast typically fall 30–40%, with drops of up to 50% in Dubrovnik and Hvar, and flights are usually 20–30% cheaper from mid-September. Big cities like Barcelona, Paris and Amsterdam hold their prices longer and don’t drop meaningfully until late October.
How far ahead should I book a September 2027 trip?
Book flights 3–6 months ahead (March–June 2027) for the best shoulder-season fares, and watch the Black Friday and Travel Tuesday sales (27 November–1 December 2026) for the year’s deepest discounts. Hotels can often be booked later — September rates soften as the month approaches.
Can you swim in the sea in September in Europe?
Absolutely — September is often the best swimming month of the year. The sea has had all summer to warm up, so the water in the Mediterranean and Adriatic is warmer in September than in June, and stays swimmable well into October in the south.
Final Thoughts: Book September, Thank Yourself Later
September 2027 is the month where everything lines up: warm seas, golden light, harvest festivals, and prices that finally make sense.
