September is the month when the world collectively exhales; the summer frenzy subsides, the crowds thin out, and a golden, mellow light seems to cast a magical glow on everything. Whether you’re chasing the last warm days on a Mediterranean beach, witnessing the vibrant awakening of a Southern Hemisphere spring, or hiking through mountains ablaze with early autumn color, September delivers.
It’s a month of harvest festivals, comfortable city explorations, and serene landscapes. Ready to take advantage of the best travel month of the year? Here are some incredible countries that are simply perfect in September.
Switzerland
While many flock to Switzerland for its peak summer greens or winter snows, September offers a unique and arguably more beautiful experience. The country is bathed in a soft, golden light as late summer gracefully transitions into early autumn. The hiking is absolutely world-class this month; the air is crisp, the trails are less crowded, and the dramatic peaks of the Jungfrau region or the iconic Matterhorn near Zermatt are crystal clear.
September is also the season of the Désalpe or Alpabzug, a wonderful tradition where farmers, dressed in festive attire, lead their beautifully decorated cows down from the high mountain pastures for the winter. It’s a joyful, authentic cultural spectacle that perfectly captures the magic of this stunning country during its most serene month.
Italy
Visiting Italy in September is like being let in on the locals’ favorite secret. The oppressive heat of August has finally lifted, replaced by warm, sun-drenched days and pleasantly cool evenings which are perfect for lingering over an al fresco dinner. The sea along the Amalfi Coast and Cinque Terre is still wonderfully warm from a summer of sun, but the beaches are far less crowded.
This is also the beginning of the harvest season, meaning it’s time for sagre (food festivals) celebrating everything from grapes in Tuscany to porcini mushrooms in the north. You can explore the ancient wonders of Rome and the Renaissance art of Florence without the suffocating crowds, experiencing the true dolce vita at a more relaxed, authentic pace.
Mauritius
If you’re dreaming of a tropical paradise without the intense humidity or threat of rain, Mauritius in September is absolute perfection. This is the heart of the island’s “winter,” which translates to one of the driest and most pleasant times of the year, with average temperatures hovering in the comfortable mid-70s.
The stunning volcanic island is yours to explore under clear blue skies. The turquoise lagoons are calm and ideal for snorkeling and diving among vibrant coral reefs. On land, the cooler weather is perfect for hiking through the lush Black River Gorges National Park to discover hidden waterfalls and unique wildlife.
Croatia
September is the month Croatia truly shines. The Adriatic Sea has been baking in the sun all summer and is at its absolute warmest temperature, making it irresistible for a swim. The relentless summer crowds, however, have started to fade, giving you more space to breathe and explore.
You can wander the stunning, ancient city walls of Dubrovnik without battling a human traffic jam, and find a perfect spot on a beach in Hvar or Brač with ease. The weather is still reliably sunny and warm, perfect for island hopping or visiting the spectacular waterfalls of Plitvice Lakes or Krka National Parks. It’s all the beauty of high season with a much more relaxed and affordable vibe.
Chile
While the Northern Hemisphere settles into autumn, Chile bursts into vibrant life. September marks the glorious arrival of spring, and the entire, incredibly long country seems to awaken from its winter slumber. In the north, the Atacama Desert can erupt into a super-bloom of wildflowers, a rare and breathtaking spectacle.
In the central region around Santiago, the vineyards are budding, and the city is buzzing with life and national independence day celebrations. Best of all, it’s an ideal time to visit Patagonia. The weather is mild, the trails are starting to open up before the summer crowds arrive, and you can witness the dramatic landscapes of Torres del Paine as they shake off the last of the snow.
Costa Rica
Don’t let the term “rainy season” fool you. In Costa Rica, September is the heart of the “green season,” and it’s a spectacular time to visit. The rainforests are at their most lush and vibrant, the waterfalls are thundering at full power, and the entire landscape is an impossible shade of emerald.
The typical weather pattern involves bright, sunny mornings perfect for activities like ziplining, hiking, or wildlife spotting, followed by afternoon showers that offer a perfect excuse for a nap or a spa treatment. With far fewer tourists, you’ll feel like you have this natural paradise all to yourself, and you’ll find better deals on some of the country’s most incredible eco-lodges.
Montenegro
Experience the dramatic beauty of the Adriatic without the crowds or the high-season price tags by visiting Montenegro in September. This small but mighty Balkan nation is a jewel, and its beauty is even more accessible this month.
The ridiculously stunning Bay of Kotor, a fjord-like inlet surrounded by towering black mountains, is serene and magical without the constant docking of massive cruise ships. The Adriatic Sea is still plenty warm for swimming, and the mountainous interior, like Durmitor National Park, offers incredible hiking opportunities in the crisp, early-autumn air. It’s a country of breathtaking contrasts that’s at its most charming in September.
Greece
September in Greece is pure bliss. The sea is arguably at its warmest and the scorching heat and the Meltemi winds of high summer have subsided, leaving behind perfectly warm, balmy days.
The islands, from the iconic blues and whites of Santorini to the vast, diverse landscapes of Crete, are still fully operational but have a more relaxed, laid-back atmosphere. You can actually get a reservation at that sought-after cliffside taverna or find a quiet spot on a world-famous beach. It’s the perfect month for island hopping, exploring ancient ruins without suffering from heatstroke, and truly soaking in the idyllic Greek way of life.
Bulgaria
For a trip that’s beautiful, diverse, and incredibly easy on the wallet, look no further than Bulgaria in September. This underrated Eastern European gem has something for everyone this month. The Black Sea coast is still warm enough for a final beach holiday, but the resorts are quiet and peaceful.
In the country’s interior, the weather is mild and pleasant, ideal for exploring ancient cities like Plovdiv, with its stunning Roman amphitheater and bohemian Kapana district. The magnificent Rila and Pirin mountains offer some of Europe’s best and most affordable hiking, with the forests beginning to blush with autumn colors. You get to experience the country’s rich history, beautiful nature, and warm hospitality without the crowds of a more mainstream destination.
Spain
Spain in September is a dream. The intense, often unbearable heat of summer has finally broken, especially in the sizzling southern region of Andalusia, making it the perfect time to explore the magnificent cities of Seville, Córdoba, and Granada. The cultural life in Madrid and Barcelona is in full swing, but the streets are less congested, allowing for more pleasant sightseeing.
On the coast, from the Costa del Sol to the Balearic Islands of Ibiza and Mallorca, the Mediterranean is still delightfully warm, and the beach clubs have a cooler, more exclusive vibe. It’s also grape harvest season in renowned wine regions like La Rioja, offering a fantastic opportunity for winery tours and tastings in a beautiful, sun-drenched landscape.
