When to Visit Naples: The Right Month for the Sea, Pompeii and Capri

When to visit Naples depends on what you want to do: the city itself works twelve months a year, with mild winters and rain concentrated between October and February. It’s the day trips that make the difference. Pompeii at two in the afternoon in July is an endurance test; the Blue Grotto often doesn’t open in November; swimming at the Gaiola has to be booked from May to September. The short answer: April–June and September–October. The long one is below, month by month, with the official climate data and the dates that change your plans. Partner prices verified regularly.

Naples weather month by month

The figures are the 1971–2000 climate averages for the Napoli Capodichino station, published in the Climate Atlas of the Italian Air Force Meteorological Service. Actual temperatures in recent years are generally 1–2 degrees higher in summer.

Autumn rain comes in short, violent downpours, not grey days; November has 10 rainy days but also plenty of sunny ones. In summer the days above 30 degrees average 15 in July and 18 in August.

When to swim

The water in the gulf is warm enough from mid-June to the end of September; May and the first half of October are fine on sunny days for anyone who doesn’t mind water around 18–20 degrees (an indicative figure, in line with the typical climatological averages for the gulf, not an official measurement). The lidos at Posillipo and Bagnoli generally open in late May and close in September. The Gaiola protected marine area applies its summer regime, with compulsory online reservation and sessions 9:00 am–1:00 pm and 2:00–6:00 pm, from May to September; the rest of the year you enter with registration, up to 200 people (areamarinaprotettagaiola.it).

September is the month to choose for the sea: water at August temperatures, beaches half empty after the 10th, hydrofoils to the islands with no queues. All the options for swimming in the city and on the islands are in the guide to the beaches.

Vesuvius and Capri: the seasonality that matters

Vesuvius. The Gran Cono path is open all year, with crater access hours that follow the seasons (parconazionaledelvesuvio.it): 9:00 am–3:00 pm from November to February, 9:00 am–4:00 pm in March and October, 9:00 am–5:00 pm in April, May, June and September, 9:00 am–6:00 pm in July and August. The ticket is online only and for a time slot (€10 full price, €8 reduced, plus fees). During an orange weather alert from the Civil Protection the path closes automatically: this happens mostly between October and March, and the announcement comes the evening before. The best months are April–June and September–October: clear air, no summer haze, bearable temperatures on the gravel. In July and August, go up at 9. Details, shuttles and tours in the guide to Vesuvius.

Capri. The island can be visited all year, but the Blue Grotto only opens when the sea is calm and the tide is low: from May to September the odds are good, in winter it often stays closed for days. Hydrofoils from Molo Beverello are frequent from Easter to October and reduced from November to March; the Monte Solaro chairlift and the boat trip depend on the weather. The From Naples: Capri, Anacapri, and Blue Grotto Full-Day Trip (€161.50, 9 hours) should be booked for a day with a calm-sea forecast, keeping a spare day in reserve. Everything in the guide to Capri.

Amalfi Coast. From April to October; the seasonal Naples–Positano–Amalfi ferries generally sail from April to October, and for the rest of the year what’s left is the SS163 by minivan and the Circumvesuviana to Sorrento. See the guide to the Amalfi Coast and Sorrento.

Pompeii in the heat and in the cold

The Pompeii Archaeological Park keeps two timetables (pompeiisites.org): 9:00 am–7:00 pm with last entry at 5:30 pm from 16 March to 14 October, 9:00 am–5:00 pm with last entry at 3:30 pm from 15 October to 15 March. In summer the site has no shade: go in at 9 and stay away from noon to 4 pm, or go in after 4 pm when the groups have left. In winter it’s the perfect visit: few visitors, low light on the streets, but with only eight hours of opening you need to arrive in the morning.

The Pompeii Guided Day Trip with Fast-Track Entry - from Naples (€45.50, 3 and a half hours) runs all year; in high season the morning slot sells out first. On the first Sunday of the month entry to state sites, Pompeii included, is free: you save the ticket price and find three times as many people. DIY versus tour, with prices, in the guide to Pompeii.

San Gennaro, 19 September

On 19 September Naples celebrates its patron saint. At the Duomo in the morning (typically at 10:00 am, with the cathedral open from 7:30 am, according to the Curia’s programme on chiesadinapoli.it) the solemn mass is celebrated during which the faithful wait for the liquefaction of the saint’s blood, kept in its ampoules; the crowd enters the cathedral from the early hours and fills via Duomo and the Decumani for the whole day. The same miracle is awaited on the Saturday before the first Sunday of May (with the procession of the saints’ statues) and on 16 December. If you want to visit the Duomo and the Chapel of the Treasure in peace, choose another day (see palaces, castles and churches). The period around 19 September is also, weather-wise, one of the best of the year: it’s worth making the dates coincide.

Christmas and nativity scenes

From late November to 6 January the city is in nativity-scene mode. Via San Gregorio Armeno with its figurine workshops is crowded from 10 am until the evening, every day; on the weekends of 8 December and before Christmas you move at a crawl. Go on a weekday morning. The lights are on via Toledo and in Chiaia, the historic nativity scenes at the Certosa di San Martino.

The weather is mild (average highs around 14 degrees, lows 5–6) but rainy at times; the days are short and the archaeological sites close at 5 pm. Pompeii and the MANN close on 25 December and 1 January; Herculaneum closes on 25 December and opens on 1 January only by special arrangement: check the calendars on the official websites. For New Year’s Eve, book your hotel well in advance.

Ferragosto and the week around it

At Ferragosto Naples empties of Neapolitans and fills with tourists: between 13 and 17 August many trattorias, neighbourhood pizzerias and shops in the centre close, while state museums, Pompeii (in the official calendar it closes only on 25 December and 1 January) and public transport keep running on holiday timetables. Islands, the Amalfi Coast and lidos are at their most crowded of the year: hydrofoils to Capri and Ischia need booking days ahead, Posillipo lidos the day before, restaurants in Positano a week before.

If your dates fall then, turn the logic on its head: do the city, empty and quiet, and postpone the islands to a weekday after the 20th. Herculaneum, smaller and shadier, copes better than Pompeii in August.

Crowds and prices: the three seasons

The Veiled Christ in the Sansevero Chapel sells out its slots days ahead in every season: it’s the first thing to book. Dated Pompeii tickets and Vesuvius time slots run out on spring weekends and from June to September. Comparison and bookings on the tickets page.

Events that move the crowds

• Easter and Easter Monday: a long weekend for Italians, Pompeii and the Amalfi Coast full; many churches with the “sepolcri” displays on Maundy Thursday.
• Maggio dei Monumenti: special openings and guided visits across the city for the whole month; the programme comes out in April on the city council website.
• 1 May and 2 June: national holidays and long weekends; Pompeii has closed on 1 May in past years, check the Park’s calendar (see above).
• First Sunday of the month: state sites free and crowded, all year.
• Festa di Piedigrotta and Pizza Village (summer) and Napoli Teatro Festival: variable dates, check the city calendar.
• Napoli football matches at the Maradona stadium: on match evenings metro Line 2 and the Fuorigrotta district are best avoided by anyone not going to the stadium.

What to pack, by season

• Spring and autumn: layers; a windproof jacket for Vesuvius and the boats, closed shoes for Pompeii and the crater, a folding umbrella from October.
• Summer: hat, water bottle (Pompeii has fountains), sunscreen, water shoes for the Gaiola and Marechiaro, a scarf for your shoulders in churches. The top of Vesuvius is windy even in July: a light sweatshirt.
• Winter: a proper jacket and waterproof shoes; the houses of the historic centre and the churches are cold, the underground sits at around 15 degrees all year.
• Always: ID for reductions (under-25s on Vesuvius, under-18s free at state sites), tickets already in your pocket or in the app, inside pockets for your phone.

If you can choose, take a week between 20 May and 20 June or between 10 September and 15 October: sea, Vesuvius, Capri and Pompeii all work, with prices and crowds still below the peak. In the other months Naples remains a good idea, as long as you know what that month takes away from you. For the day-by-day programme start from the itineraries and the day trips from Naples.
