September is one of the best months to explore Europe. The heat has mellowed, the crowds have thinned, and the sea is still warm from summer. If you’re looking for that perfect mix of golden days and quieter nights, these destinations are made for soaking up the September sun.
Spain
Mallorca (Port de Sóller)
In September, Mallorca trades the bustle of August for a calmer, more local feel. Port de Sóller is a charming base, with its sheltered bay and Tramuntana mountains just steps away. You can ride the vintage wooden train to Palma, hike sections of the GR221, and still have time for a late-afternoon swim.
Costa Brava (Tossa de Mar)
Tossa de Mar’s turreted castle towers over a sandy crescent beach, and the old town’s narrow lanes still feel authentically Catalan. September brings cooler, clearer days — perfect for walking the Camí de Ronda coastal trail to discover hidden coves and quiet viewpoints.
Valencia
This Mediterranean city blends beach life with cultural punch. Cycle along the old riverbed park, explore the futuristic City of Arts and Sciences, then head to Albufera for sunset boat rides and the original paella. September means warm sea temperatures and less-crowded sands.

Canary Islands
Tenerife
Tenerife’s beaches and volcanic trails are still bathed in sunshine in September. The island’s varied microclimates mean you can sunbathe on the coast and hike in cooler mountain air on the same day. Always respect beach flags — rip currents can be dangerous even in calm-looking seas.

Gran Canaria
Gran Canaria offers both a lively capital, Las Palmas, and wild mountain scenery inland. In September, you can spend mornings on the city’s long sandy beach, then head up to cooler hill villages in the afternoon. The same flag system applies here — swim only when it’s safe.

Portugal
Algarve (Lagos)
In September, Lagos basks under sunny skies while the summer crowds thin. Dramatic cliffs and golden beaches frame the town, and you can take boat trips into the grottoes of Ponta da Piedade. The evenings are balmy, perfect for seafood dinners along the marina.

Costa Vicentina
Part of the Southwest Alentejo and Vicentine Coast Natural Park, this wild stretch of Portugal’s coast offers dramatic cliffs, sandy coves, and authentic fishing villages. September brings warm, sunny days ideal for exploring the Fishermen’s Trail. Public transport is limited, so a rental car makes it easier to reach remote spots.

Madeira
The “island of eternal spring” is particularly pleasant in September. Madeira’s levada paths lead through lush valleys to waterfalls, while volcanic peaks offer sweeping views. Out at sea, dolphin-spotting trips are common, and the island’s gardens are still in full bloom.

Azores (São Miguel)
São Miguel combines volcanic landscapes with a slow, welcoming pace of life. In September, you can bathe in the hot springs of Furnas, hike around crater lakes, and watch whales offshore — all without high-season queues.
Italy
Ischia
This volcanic island in the Bay of Naples is famous for its thermal springs and lush gardens. September’s gentle warmth makes it easy to alternate spa days with swims in the Tyrrhenian Sea, and the island’s villages are lively without being crowded.
Sicily (Taormina/Ortigia)
By September, Sicily’s fierce summer heat has eased, but the sea remains warm. Taormina’s ancient theatre and Ortigia’s baroque piazzas are radiant in the softer light, while nearby Mount Etna and coastal gorges add adventure to the mix.
Sardinia
Sardinia in September offers Caribbean-blue seas alongside rugged hiking in the interior. You can explore Gorropu Canyon in the morning, swim in a secluded cove by afternoon, and finish with fresh seafood in a harbour town. Public transport is available but slow, so having your own wheels makes it far easier to link beaches, towns, and hiking trails in one trip.
See our guide to Sardinia for more details.
Trieste
This elegant Adriatic city blends Italian, Austrian, and Slavic influences. September brings mild weather for strolling along the seafront, savouring time in historic cafés, or taking short trips into the vine-covered Karst hills.
Croatia
Zadar
With Roman ruins, a charming old town, and ferries to nearby islands, Zadar makes a relaxed Adriatic base. In September, the heat softens but the sea stays warm, perfect for combining culture with island-hopping day trips.
Dalmatia (Split–Hvar–Dubrovnik)
Warm and sunny in September with calmer streets and harbours after summer. Combines historic old towns, scenic ferries between islands, and coastal hiking paths.

Istria (Pula/Motovun)
Istria is known for its truffles, wine, and romantic coastal towns. In September, vineyards are in harvest, and the Adriatic remains inviting for a swim.

Malta
Malta stays sunny well into September, with warm seas and long daylight hours. Valletta’s golden stone streets are steeped in history, while Gozo offers rural charm, cliff walks, and hidden swimming spots.
