Is September Right for You?
Weigh the advantages and considerations before booking
Advantages
- + September is Portonovo's quietest month - you'll have the Conero Riviera's limestone coves almost to yourself, at sunrise when fishing boats still outnumber swimmers.
- + The grape harvest begins mid-month; tractors loaded with Verdicchio clusters crawl through the inland lanes, and cantine sociali open their doors for first-press tastings that tourists rarely know exist.
- + Sea temperature holds at 23°C (73°F) - warm enough for long swims without the August crush, and the afternoon seabreeze finally knocks the humidity back to tolerable levels.
- + Hotel rates on the bay drop 30-40 % from August peaks. Same sea-view balconies that were booked solid in summer now get last-minute availability at mid-week prices.
Considerations
- − Afternoon thunderstorms roll in fast - one moment you're sunbathing on Spiaggia di Mezzavalle, the next you're sprinting for the tree line as lightning forks over Monte Conero.
- − Half the lidos (beach clubs) pack up after Ferragosto. By late September only the year-round kiosks remain, so sun-lounger choice shrinks and music shuts off early.
- − Inland truffle fairs and sagre pull locals away from the coast at weekends, meaning some waterfront restaurants close one or two nights without warning.
Best Activities in September
Top things to do during your visit
Conero Ridge Hiking Trails
September gives you morning temperatures around 22°C (72°F) and clear skies good for the 12 km (7.5-mile) traverse from Portonovo to Sirolo along the Anello del Conero. Wild fennel lines the path, and the Tyrrhenian glitters 300 m (980 ft) below every time the maquis thins. Afternoon heat stays below 27°C (81°F), so you won't melt on the final climb up to Passo del Lupo.
Booking Tip: Trailheads start right behind the portonovo.com booking widget below lists local guides who supply k-way ponchos for the odd shower.
Verdicchio Wine-Harvest Estate Tours
Third-week September the cantine around Jesi switch from machine to hand-picking. You can follow tractors into the vineyards, taste grapes straight from the bin, then watch the first must ferment in stainless-steel tanks that smell like fresh-cut apple and yeast. Morning fog in the valleys burns off by 10 am, leaving golden light that photographers dream about.
Booking Tip: Book 7-10 days ahead. Small estates cap visits at twelve people. Licensed operators (see current options in booking section below) include transport from Portonovo hotels.
Sea-Kayaking Portonovo Bay
With August jet-skis gone, the bay regains its natural soundtrack of paddles dipping and gulls overhead. Water is still 23°C (73°F), so capsizing isn't a shock, and low-season light gives the white cliffs of Due Sorelle sea stacks a soft pink glow by 5 pm. Morning winds stay under 8 knots - good for beginners.
Booking Tip: Start at 8 am when the sea is glassy. Afternoon breezes pick up quickly in September. Current tours in the booking widget below supply dry-bags for phones.
Underground Ancona Street-Food Walks
Rainy spells? Head 12 km (7.5 miles) north to Ancona's covered Pescheria market and the WWII tunnels turned wine bars. September menus lean on moscioli (wild mussels) just back in season and fried olive ascolane stuffed with three-day-aged veal. Humidity makes a cold Verdicchio spritz taste even better.
Booking Tip: Afternoon tours start at 4 pm to dodge thunder cells. Licensed guides meet at Teatro delle Muse - see current schedules in booking section.
Portonovo Evening Aperitivo Fishing Piers
Sunset slips behind the western headland at 7:30 pm, painting the old trabucco boats copper. Local fishermen hang lanterns on the pier and sell glasses of yeasty, unfiltered Verdicchio for the price of a polite chat. It's technically not a business - more a social ritual - so you'll need cash in your pocket and a basic grasp of "salute."
Booking Tip: No booking needed. Show up any clear evening after 6:30 pm. Bring a light jacket - sea breeze drops the felt temperature 5°C (9°F) once the sun dips.

September Events & Festivals
What's happening during your visit
Mid September (usually the third weekend)
Festa dell'Uva di Jesi
Jesi's historic centre closes to traffic for a weekend of grape-themed floats, free Verdicchio tastings in medieval cellars, and folk bands that parade past Palazzo Pianetti. Locals wear purple scarves. Visitors who bring a glass get unlimited refills from sidewalk barrels.
Late September (last Sunday)
Sagra del Mosciolo
Portonovo's tiny hamlet celebrates the wild mussel that grows on Conero rocks. Grilling happens on makeshift drums by the chapel. Mussels are served by the paper-cone with lemon wedges and a bay leaf. It's small - maybe 200 people - and finishes when the last crate is empty, usually Sunday around 3 pm.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
If thunder rumbles at 2 pm, drive 10 minutes to the Abbazia di San Pietro in Portonovo. The Romanesque crypt stays a cool 12°C (54°F) year-round and you'll probably have it to yourself.
Skip the panoramic road to Sirolo at sunset - tour buses clog it. Instead, take the inland lane through Villarey. Olive groves glow gold and you'll arrive faster.
The free public beach by the torrettore tower has colder water because an underwater spring feeds in - locals dive here after a hike to cool calves instantly.
Restaurants reopening after August break often run "menu di rientro" specials first week September - shorter menus but cheaper wine to lure locals back.
Avoid These Mistakes
Assuming ferries to Conero islands run daily - service shrinks to weekends-only after mid-September; check the notice board at the marina each evening.
Reserve pool hotels for late September. Check heating policy first. Nights drop to 20°C (68°F). Most outdoor pools feel cold then.
Plan sunrise hike for 5:30 am. Italians shift to winter time last September weekend. Dawn arrives one hour later overnight.
