Sicily August is performance — beach clubs, boat parties, 40-degree heat, the island processing 3 million visitors. Sicily September is reality — the harvests, the fishing resuming on the autumn schedule, the archaeological sites walkable in the morning without burning, and the Sicilian families who run the agriturismi and the trattorie having a conversation with you about the summer. September is when Sicily is most accessible and most itself.
Read the guide →September weather in Sicily: average daytime temperature 24–28°C, warmer inland (25–30°C in the Palermo plain and the Agrigento south) than coastal (22–26°C on the Tyrrhenian north coast, 24–27°C on the Ionian east coast). The specific September advantage over August: the Sirocco (the hot, dry wind from the Sahara that pushes temperatures above 35°C in Sicily in July–August) has typically reduced in frequency by September — September heat is Mediterranean rather than Saharan, meaning the humidity is higher and the heat is less desiccating than August. Sea temperature: 26–28°C on the Ionian coast (warmest), 25–27°C on the south and west (slightly cooler). These are the warmest Sicilian sea temperatures of the year — September consistently 1–2°C warmer than August due to the thermal lag.
The September rainfall dynamic: Sicily is the driest region in Italy — the annual rainfall in Palermo is approximately 600mm, concentrated in October–March. September is within the dry season but the first autumn storm events are possible from mid-September onward. Most September days in Sicily are entirely dry. The specific September landscape: the summer drought has bleached the interior landscapes (the Sicilian cereal fields that are intensely green in April–May and gold in July become post-harvest stubble grey by August); the September interest is not in the agricultural landscape but in the harvest events — the grape processing, the olive assessment (the olives are approaching maturity but not yet harvested — this happens October–December, making September the last month of the olive's summer colour before the autumn harvest begins).
Sicily's Greek archaeological sites — the Valley of the Temples (Agrigento), Selinunte, Segesta, and the Siracusa Parco Archeologico — are at their most comfortable for extended visits in September. The specific improvement over August: the August heat (35–40°C in the open agricultural landscape south of Palermo and at Agrigento) makes sustained archaeological walking physiologically demanding; the September temperature (25–28°C with lower humidity) makes the same sites comfortable. The Valley of the Temples at 9am opening in September: the shadow still extends from the Greek columns across the wildflower-free (summer-dried) ground, the tourist coach pressure is approximately 40% of August, and the light on the south-facing limestone of the Temple of Concordia has the specific early autumn quality — lower angle, warmer colour temperature — that photographers consistently prefer to the harsh flat August light.
September is one of the two best months for Sicily (with May). Advantages: the sea is warmest (26–28°C on the Ionian coast), crowd density is 35–50% below August, prices drop 25–35% below August peak, the grape harvest begins (Marsala, Nero d'Avola, Etna Rosso), the archaeological sites are comfortable to visit without August's heat, and the September atmospheric light quality improves photography at all sites. The specific September disadvantage over May: the landscape is at its driest (summer drought has bleached the interior) and the wildflower context (which makes May extraordinary) is absent. Both months are significantly better for Sicily than August for most visitor profiles.
Sicily's grape harvest (vendemmia) calendar by variety: Moscato di Pantelleria (the dessert wine from the island of Pantelleria, south of Sicily — the earliest harvest, typically late July to mid-August); Zibibbo table grapes (August); Grillo, Catarratto, and Ansonica for Marsala (September); Nero d'Avola (the most important Sicilian red grape, harvested mid-September to early October in the Avola zone of the Siracusa province); and Etna Rosso grapes (Nerello Mascalese, harvested October on the volcanic slopes). The September harvest period — Marsala and early Nero d'Avola — is the most accessible for visitor participation (winery tours with harvest observation, and in some cases grape picking participation by prior arrangement with the winery).
Days 1–2 (Palermo): Palermo markets (Ballarò, Vucciria morning fish market), Palazzo dei Normanni, Cappella Palatina (the most complete Byzantine-Norman mosaic interior in Europe), street food (arancine at Bar Bristol, panelle at any Ballarò stall).
Day 3 (Marsala harvest): Drive to Marsala (2 hours west of Palermo). Florio winery tour (book ahead, €12, morning). Marsala town salt flats (Saline di Marsala, the windmills and salt pans south of town — the most specifically Marsala landscape). Agriturismo dinner.
Days 4–5 (Agrigento and south): Valley of the Temples (morning opening, 9am, before heat). Afternoon: drive east along the southern coast to Noto (Val di Noto baroque, the Caffè Sicilia granita). Day 5: Siracusa (Parco Archeologico, Ortigia island morning walk).
Days 6–7 (Catania and Etna): Catania fish market (La Pescheria, 7–11am). Afternoon: drive up Etna (cable car from Rifugio Sapienza, €28). Day 7: drive Taormina (Teatro Greco 8:30am) before return to Palermo or Catania airport.
September Sicilian food calendar: the first fresh Trapani tuna (tonno di Trapani — the Bluefin tuna that has been migrating through the Sicily Strait since ancient times, caught by the last traditional tonnara at Favignana island, available at the Favignana fish market and at the best Palermo fish restaurants from September); the Nero d'Avola grapes as table grapes (the large, dark, sweet grape sold at market stalls in the Siracusa and Ragusa area before the wine harvest begins); the prickly pear (fico d'India — the opuntia fruit that is the most specifically Sicilian September street food, sold peeled and cold from vendor carts across the island, €1–2 for a bag of 5–6 fruits); and the early dried figs (fichi secchi — the September second fig harvest, pressed with almonds and dried in the Ragusa province traditional manner).

La Redazione di TourLeaderPro.comItalian train travel includes several routes that are genuinely extraordinary as experiences rather than merely as transport — where the journey is the destination:
Circumvesuviana Naples–Sorrento (line EAV): The narrow-gauge suburban railway running from Naples Porta Nolana (adjacent to the main Napoli Centrale station) around Vesuvius to Sorrento — passing through Ercolano (for the Herculaneum archaeological site), Pompeii Scavi (for Pompeii), and Torre Annunziata (for the Oplontis villa, the least visited major Roman site in Campania). The trains are old, often crowded, and invariably used by pick-pockets in the Naples sections — watch your belongings. But the route provides the most efficient access to three UNESCO archaeological sites on a single line. Ticket: €3.60 for the full Naples–Sorrento journey (75 minutes), available at the Porta Nolana station or the Circumvesuviana information points. Bernina Express (Tirano, Italy to St. Moritz, Switzerland): The Bernina line between Tirano (Lombardy, accessible by train from Milan in 2.5 hours) and St. Moritz crosses the highest railway pass in the Alps (the Bernina Pass, 2,253m) on a regular-service narrow-gauge train (Rhaetian Railway, UNESCO 2008 — one of the few railway lines with UNESCO designation for its engineering and landscape). Ticket: €35–60 from Tirano to St. Moritz depending on class and booking time, book at sbb.ch. The route includes the famous Brusio circular viaduct (the train makes a full 360-degree spiral loop to gain altitude — visible from the train window). Domodossola–Locarno (Centovalli Railway): The 52km narrow-gauge line crossing the Centovalli (Hundred Valleys) between Domodossola (Piedmont, accessible from Milan by train in 1 hour) and Locarno (Switzerland) through 83 bridges and viaducts, 31 tunnels, and the most uninhabited and dramatic valley landscape of the Italian Alps. Ticket: €30 round trip from Domodossola to Locarno, book at centovalli.ch.
Italy's most scenic railway journeys: Bernina Express Tirano–St. Moritz (UNESCO, alpine pass at 2,253m, the circular Brusio viaduct, €35–60 each way); Domodossola–Locarno Centovalli Railway (83 bridges, 31 tunnels, the most dramatic uninhabited valley in the Italian Alps, €30 round trip); Circumvesuviana Naples–Sorrento (archaeological sites en route — Herculaneum, Pompeii, Oplontis — with the Vesuvius volcano visible throughout, €3.60 full journey); and the Rome–Palermo overnight train (the ferry crossing between Villa San Giovanni and Messina where the carriages are loaded onto the ship — the most unexpected Italian train journey moment, included in the standard rail ticket). The Rome–Palermo train is the last operational passenger train ferry crossing in the Mediterranean — the carriages are literally rolled onto the ferry, crossed the Strait of Messina, and rolled off on the Sicilian side.
The Italian morning market (mercato rionale) is the most directly authentic Italian cultural experience available — no tourism organisation, no guidebook staging, no English-language interpretation. Just the city's residents buying their food from the producers and merchants who have been supplying them for generations. The specific markets worth knowing:
Bologna Quadrilatero (Tuesday–Saturday, 7am–1pm): The most beautiful Italian urban food market — the medieval street grid between Piazza Maggiore and Via Rizzoli, with the market stalls of the most celebrated food city in Italy. The specific Bologna market products: the mortadella (the original large-diameter cooked pork sausage, DOP since 1998, available from the specialist vendors at La Baita cheesemonger in the quadrilatero — the most complete Bologna food shop, Via Pescherie Vecchie 3a); the tortellini in brodo available from the market-side rosticceria (hot food counter) at 11am; and the Parmigiano-Reggiano wheel sections sold directly by the producers who bring them to the Quadrilatero on Saturday morning. The best food market in Italy for the combination of product quality and architectural setting. Catania La Pescheria (Monday–Saturday, 7–11am): The most performatively theatrical fish market in Italy — the vendors in the Piazza del Duomo fish market section shout, negotiate, and display simultaneously. The specific product: the swordfish brought from the Strait of Sicily, the sea urchins (ricci di mare) served raw in the shell at the market edge, and the specific local fish vocabulary (the Catanese names for fish differ from the Italian standard — ask "come si chiama in catanese?" for the local name). Mercato di Porta Palazzo, Turin (Tuesday–Friday morning, Saturday all day): The largest open-air market in Europe (by vendor count — approximately 800 daily vendors in the Piazza della Repubblica) and the most culturally diverse market in Italy — the market reflects Turin's specific immigration history (Moroccan, Senegalese, Chinese, and southern Italian communities all have specific sections). The Porta Palazzo market also has the most complete selection of Piedmontese agricultural products outside the Langhe production zone itself: white truffles in season (October–December), Barolo and Barbaresco producers at direct-to-consumer prices, and the specific Piedmontese winter vegetables (cardoons, the specific Castelfranco radicchio, and the mostarda piemontese).
Italy's best markets: Bologna Quadrilatero (Via Pescherie Vecchie and adjacent streets, Tuesday–Saturday 7am–1pm — the finest urban food market in Italy, mortadella, tortellini, Parmigiano at the source); Catania La Pescheria (Piazza del Duomo area, Monday–Saturday 7–11am — the most theatrical fish market, swordfish and sea urchins directly from the fishermen); Turin Porta Palazzo (Piazza della Repubblica, Tuesday–Saturday — the largest open-air market in Europe, Piedmontese agricultural products and truffle season); Rome Campo de' Fiori (Piazza Campo de' Fiori, Monday–Saturday morning — the most centrally accessible Rome market, though increasingly tourist-oriented); and the Rialto Market Venice (Pescheria — fish, Tuesday–Saturday 7am–noon, the most historically continuous Italian market site, in the same location since the 13th century).
Italy has the oldest and some of the finest botanical gardens in the world — the first university botanical gardens were founded in Pisa and Padua in 1544–1545, creating the model that spread to every European university in the subsequent century. The most important:
Orto Botanico di Padova (1545, UNESCO 1997): The oldest surviving university botanical garden in the world, founded by the Padua medical school for growing medicinal plants. The original circular garden design (the hortus conclusus surrounded by a circular wall with four entry points, representing the four seasons and the four humors) is intact and is one of the finest examples of Renaissance garden design in Italy. The garden contains approximately 6,000 plant species; the most famous individual: the Goethe's Palm (a Phoenix dactylifera date palm planted in 1585 that Goethe visited in 1786 and wrote about in his Italian Journey, connecting its structure to his theory of plant metamorphosis). The 1585 palm and the 1595 Victoria regia pool (the giant water lily, one of the first specimens cultivated in Europe) are the two most visited individual plants. Entry €10, open daily, ortobotanicopd.it. Orto Botanico di Palermo: The most beautiful botanical garden in Italy for its tropical character — the Mediterranean climate of Palermo allows outdoor cultivation of tropical species that require greenhouses elsewhere. The Ficus macrophylla (the Moreton Bay fig, planted in 1845 — the aerial roots extending over 4,000 m², the most extensive single-tree root system in Europe, visible from the garden entrance) is the most extraordinary tree in Italy. Entry €5, open daily. Giardino Botanico Hanbury, Ventimiglia (Liguria): The most diverse in plant species — founded in 1867 by Thomas Hanbury (a British merchant who made his fortune in Shanghai and retired to the Ligurian coast), with 5,800 plant species from the world's Mediterranean-climate zones (California, Australia, South Africa, Chile, and the Mediterranean basin) all growing in the same coastal garden. Entry €9, open daily except Tuesday, jardinhanbury.com.
Italy's most significant botanical gardens: Orto Botanico di Padova (1545, UNESCO — the world's oldest surviving university botanical garden, Goethe's Palm planted 1585, €10); Orto Botanico di Palermo (the most beautiful for tropical character, the Ficus macrophylla with 4,000 m² root system, €5); Giardino Botanico Hanbury near Ventimiglia (5,800 species from all Mediterranean-climate world zones, €9); Villa Taranto botanical garden on Lake Maggiore (the most deliberately comprehensive 20th-century botanical collection in Italy, 20,000 species including the Victoria regia, €12, Verbania Pallanza); and the Orto Botanico di Roma (Largo Cristina di Svezia 24, Rome — 8,000 species in the Trastevere hill, €8, the most accessible Italian botanical garden from a major tourist destination).
