September is the month I would recommend first, and not for the sake of originality: because the sea keeps the heat it has built up over two months of sun while the people go away. From the second week the day trippers thin out, tables on the Corricella quay become available again, and the light — lower, warmer — is the best of the year for photographing the coloured facades.
The month has three dates that decide your plan, and we will set them out at once: 15 September, when the evening return by hydrofoil ends; 25 September, when Vivara cuts its visits back to three days; and 29 September, the great feast of San Michele. Ignore those three and the month has a surprise in store for you.
On the climate we do not publish numbers. We have no climate data for Procida from a reliable meteorological source and we do not fill tables with estimates. The local sources speak of a climate that is mild all year, never muggy in summer and never harsh in winter. The relevant fact for September is a different one, and it is not an air temperature: the sea stays warm because it gives up the heat it has stored slowly.
The three dates that change the plan
15 September. This is the last day of the Caremar hydrofoil at 20:05 from Procida to Naples, a sailing that only runs from 15 June. After that date the last useful return becomes the 20:15 ferry. The difference looks minimal and it is substantial: anyone on a day trip loses the convenient window for dinner on the island. The rest of the timetables are on the page for ferries to Procida.
25 September. From this day the Vivara reserve switches to a reduced calendar: Friday, Saturday and Sunday only, with a single departure at 09:30. Before that, from 11 September, there were two departures, at 09:30 and at 16:00. Monday is closed all year. If Vivara is on your list and you are travelling in the last week of the month, the reserve decides your arrival day, not you.
29 September. The feast of San Michele Arcangelo, the island’s patron saint. It is the second date of the year, after the one on 8 May, and it is the one that matters more. The centre of it is the abbey at the top of Terra Murata: a monastic presence here is documented from 1026, and 2026 is the Year of the Millennium. The full picture is on the page for the feast of San Michele.
Then there is one date that does not change: the 21:05 hydrofoil from Naples stays in service until 30 September. Anyone arriving on the island can do so late in the evening all month.
The sea, which is the real argument
The reason September beats June is simple: the same water, fewer people. The island’s beaches this month can be enjoyed in a way that does not exist in August.
The Chiaia is the most sheltered and secluded bay, of dark volcanic sand, with shallow water that suits children. You get there only on foot, down a long stairway — sources say 182 or 186 steps, so about a hundred and eighty — or with the boat service from Corricella. In September that stairway is far less punishing than in August, and at the bottom you find room.
The Chiaiolella is still the most convenient and best served, with direct road access and the L2 bus from the port: beach clubs, bars and restaurants along the front, sun all day, the view of Vivara and Ischia. Next to it, the Ciraccio is longer and catches the mistral in the afternoon.
Pozzo Vecchio beach, the Il Postino one, reached on the C1 bus or twenty minutes on foot from the port, is particularly good in September: little shade, but the sun is no longer the August one. The Silurenza, just west of the port, remains the choice for anyone with a hydrofoil to catch and an hour to spare.
The boat trips are all still running. The same argument always applies: you only really understand Corricella from the water, and in September the boats are not full.
What is open, what starts to close
September is still full season: the tourist season runs from Easter to early October. Restaurants, beach clubs and experiences are operating all month, with a few closures towards the end.
The abbey of San Michele Arcangelo is within its period of opening to visitors, which runs as far as All Saints’, 1 November. Free entry with a voluntary donation. Two warnings: in 2026, the Year of the Millennium, the calendar may be subject to changes without notice, and the underground chambers cannot currently be visited, despite many guides still presenting them as part of the visit.
Palazzo d’Avalos is still the island’s strongest visit: 13.00 EUR, guided only, booked two days in advance, minimum two and maximum twenty people, about an hour inside the former Bourbon prison. The opening hours published online do not agree: get your slot confirmed in writing before you tackle the climb.
For Vivara the usual rules apply — guided visits only, compulsory online booking, a maximum of 25 visitors per slot, closed on Mondays, walking boots compulsory and flip-flops forbidden — plus the reduction from 25 September. The ticket costs 10.00 EUR for adults, 3.00 EUR for children between 8 and 12, free under 7. The visit lasts on average two and a half hours. The official calendar is published as far as 1 November 2026.
Crowds, prices and the rule about cars
The context figure: in the summer of 2026 the island recorded 236,000 sea arrivals, a thousand fewer than the year before, against more than 860,000 for Ischia and about 1,050,000 for Capri. Procida is not built around mass tourism, and in September you can see it: from the second week the numbers drop sharply.
On prices, September slides progressively towards the lower part of the bands recorded — 80-180 EUR for a double in a three-star or a B&B, 160-280 EUR for a sea-view four-star. The last week of the month is often the best value of the whole swimming season.
On cars, no exemption: the ban on landing and driving for non-residents’ vehicles applies until 15 October 2026, with fines from 430 to 1,731 EUR, reduced to 301 EUR within five days. September falls entirely inside the ban period. The dates of the decree change every year: details, exemptions and authorisations in the practical information.
If you have two or three nights, September is the month in which that format works best: look at a weekend in Procida. The comparison with the other good months is in when to visit Procida.
