Best Time to Visit Naples: Weather, Crowds & Day Trips

The one Naples plan that does not depend on the weather or the season is a pizza class, and the dates and start times for the most-reviewed class are below.

Naples by season

Winter, December to February. Usual highs are 13 to 14°C with lows around 5°C, and about nine rainy days a month. Daylight runs from about nine and a half to ten and a half hours. Hotel stays across Campania fall to between a sixth and a quarter of the August level, and Pompeii’s monthly visitor counts in 2023 and 2024 were about 110,000 to 145,000, well under half of May’s. The museums, the catacombs, the food and the pizza classes carry on as usual. The day trips are shorter: Pompeii and Herculaneum are on their winter timetables, Vesuvius crater access ends at 15:00 from November to February, and snow and ice closed the crater trail at the end of March in 2026, until it reopened on 1 April. The sea is about 14 to 18°C, so swimming is not the plan. Capri boats run all year, and a booking site counts 7 to 8 hydrofoil departures a day from Naples in autumn and winter.

Spring, March to May. March averages 16°C and April 19°C, both with about nine rainy days, and May reaches 24°C with about six. Daylight grows from 12 to about 14½ hours. March is the changeover: Pompeii’s timed slots begin on 16 March, and its visitor counts in March were about 240,000 to 270,000, roughly half of April’s. April and May are as busy at Pompeii as any month, with about 470,000 to 520,000 visitors. Vesuvius crater access runs to 16:00 in March and 17:00 from April, and the Blue Grotto moves to its longer summer hours in April. The sea is still cool, about 14 to 19°C. Easter falls on 5 April in 2026 and 28 March in 2027, and 25 April and 1 May are public holidays.

Summer, June to August. Highs climb from 28°C in June to 31°C in August, nights stay around 21°C in July and August, and July is the driest month with about two rainy days. Daylight reaches 15 hours in June. The sea is about 22 to 27°C. Pompeii and Herculaneum are on their long timetables, and Pompeii’s monthly counts sit at about 410,000 to 460,000, similar to spring. August is the busiest month for hotel stays across the region, and Ferragosto on 15 August is a public holiday. The Ministry of Health publishes heat-wave bulletins for Naples from late May to September, and the city advises avoiding outdoor activity from 11:00 to 18:00 when an alert is in force.

Autumn, September to November. September keeps summer’s warmth, with highs near 27°C, a sea of about 25°C and about six rainy days. Hotel stays across the region are still at about four-fifths of August. October cools to 23°C with about eight rainy days, and Pompeii still draws about 445,000 to 480,000 visitors. From 15 October Pompeii and Herculaneum move to their winter timetables. November is the wettest month, with about ten rainy days, and Pompeii’s visitor counts drop to about 180,000 to 190,000. All Saints’ Day on 1 November is a public holiday, and a law passed in 2025 adds 4 October from 2026.

Other Naples Experiences You Might Enjoy

Beyond the city, you can book hands-on Neapolitan pizza classes, guided visits to Pompeii and Herculaneum, Vesuvius excursions, boat trips to Capri and Amalfi Coast tours from Spaccanapoli and Via dei Tribunali.

Check your date

Your date in Naples

Choose a date to see sunset in Naples, the usual weather and sea temperature for that month, and which of the main sites are on their summer or winter timetable. Pompeii, Herculaneum, Vesuvius, the Blue Grotto and the museums each change their hours through the year.

Sunset is calculated for Naples. Temperatures, rainy days and sea temperature are averages for the month, not a forecast. Site hours are the timetables published in September 2026 and can change.

Pompeii’s own visitor counts show a long plateau, not a summer peak: about 410,000 to 520,000 visitors a month from April to October in 2023 and 2024, then a fall to about 180,000 to 190,000 in November and about 110,000 to 145,000 from December to February. From 16 March to 14 October the morning slot admits up to 15,000 people and the afternoon slot up to 5,000. The park’s timetable gives no slot limits for the winter period.

On the Amalfi Coast, the coast road, the SS163, had an alternate number-plate rule in 2026 from 10:00 to 18:00: every day at Easter and from 25 April to 2 May, weekends and holidays in June, July and October, and every day in August and September. These dates were set for 2026 and can change. The current status of the Path of the Gods is not established, so check with the Comune di Agerola before you plan the walk.

In the city, the national archaeological museum (MANN) is open 9:00 to 19:30 and closed on Tuesdays. The Capodimonte museum and the catacombs are closed on Wednesdays, and the catacombs are also closed on 25 December. Napoli Sotterranea runs tours every hour from 10:00 to 18:00.

The hotel-stay column shows nights spent in registered accommodation across the Campania region, with August 2025 as 100. It covers Naples and also the Amalfi Coast, Sorrento, Capri and Pompeii, so it shows how busy the region is with hotel guests and not how busy the city streets are. The Pompeii column gives the range of the 2023 and 2024 monthly ticketed entries, and it counts Pompeii only.

Holidays and events

Italian public holidays fall on 1 January, 6 January, Easter Monday (6 April 2026 and 29 March 2027), 25 April, 1 May, 2 June, 15 August, 1 November, 8 December, 25 December and 26 December. The 2025 law that adds 4 October from 2026 leaves it unclear how far that day works as a full day off. When 2 June or 8 December falls on a Tuesday, the national archaeological museum has opened on the Tuesday and closed on the Wednesday instead.

The America’s Cup preliminary regatta runs in Naples from 24 to 27 September 2026, and the America’s Cup Match in the Gulf of Naples starts on 10 July 2027. If your dates overlap, book accommodation early. The city’s Maggio dei Monumenti programme ran from 2 May to 2 June in 2026, with more than 200 events, and dates for 2027 had not been published when we checked. San Gregorio Armeno, the street of nativity workshops, is busiest from about late November to 6 January, according to a travel blog.

A plan that does not depend on the weather

When rain, heat or a rough sea rules out a day trip, a pizza class is the Naples plan that stays the same in every season. Our guide to the best time for a Naples pizza class lists the days each class runs and the start times on offer, and our guide to the best pizza-making classes in Naples compares the formats.

How we know

Site hours and rules. Pompeii, Herculaneum, Vesuvius, the Blue Grotto, the national archaeological museum, Capodimonte and the catacombs come from each site’s own published timetable and ticket pages, read on 19 September 2026. The Blue Grotto’s ministry and operator pages differ slightly on the opening time, so the page says “about”. The Amalfi road rule is the 2026 ANAS ordinance as republished by the Comune di Praiano.

Visitors. Pompeii’s monthly counts are ticketed entries for Pompeii only, from the archaeological park’s Italian visitor-data page, for 2023 and 2024. Herculaneum is a separate park and has no monthly figures there. No monthly counts for the national archaeological museum were found. Hotel stays are from Eurostat’s monthly table of nights spent in tourist accommodation (dataset tour_occ_nin2m) for Campania, 2023 to 2025.

Weather and sea. Usual highs, lows and rainy days are 1991 to 2020 averages for the Napoli Capodichino weather station, about 5 km north of the historic centre. The official files could not be opened on 19 September 2026, so the temperatures come from a published transcription of the ISPRA normals and match a second source within 0.3°C. Rainy days come from two secondary sources that differ by about a day. Sea temperatures come from two sea-temperature sites, temperatura-del-mare.it and seatemperature.net, neither of which states its data period, so the table shows the range of the two.

Boats, heat and dates. The Capri departure counts come from a third-party booking site, because none of the operator pages we read gave a count. The April to October season for Amalfi hydrofoils is from third-party guides. The heat-wave bulletin season is from the Ministry of Health’s announcement and the city’s own notices. Event dates for Maggio dei Monumenti are from local press, and Christmas dates are from a travel blog. Sunrise and sunset are calculated for Naples with the standard solar-position method and agree with published tables to within about seven minutes. Italian public holidays follow Law 260 of 1949 as amended by Law 151 of 2025.

Where the evidence stops. The weather figures are averages, not a forecast for your day. The hotel-stay series is a proxy for how busy the region is with hotel guests. It leaves out stays booked through short-let platforms and does not measure how busy the streets are. Pompeii’s counts cover two years, so they show a pattern and not a rule. Timetables were read on one day and change from year to year, including the mid-October and mid-March switch dates and the 2026 road rule. No source we found publishes how often the Capri boats or the Blue Grotto are cancelled, so the page does not give a rate.

Frequently asked questions

What is the best month to visit Naples?

It depends on the trip. For a first sightseeing trip, May, June and September offer the best overall balance. If beaches and boat days matter most, June to September suits the sea. For fewer people at Pompeii, choose November to February.

Is August too hot for Naples?

August has the highest usual daytime high, about 31°C, and nights stay around 21°C. Pompeii, Herculaneum and Vesuvius are open-air, and the morning is the cooler part of the day. August is also the busiest month for hotel stays across Campania.

What is the best time to visit Pompeii?

Pompeii's monthly visitor counts were similar from April to October in 2023 and 2024 and far lower from November to February. From 16 March to 14 October entry is by timed slot, and the winter timetable closes about two hours earlier. In hot months the morning is the cooler part of the day.

Is Naples worth visiting in winter?

Yes, for the city. The museums, catacombs, food and pizza classes run all year, usual highs are 13 to 14°C, and Pompeii has well under half of its May visitor numbers. The day trips are shorter, because Pompeii closes about two hours earlier and the Blue Grotto and the Capri boats depend on calm water.

When is the sea warm enough to swim in Naples?

Two sea-temperature sites put the sea at about 22 to 27°C from June to September and about 22°C in October. From January to April it is about 14 to 16°C.

Does it rain a lot in Naples?

November is the wettest month, with about 10 rainy days, and rain stays frequent from October to March. July is the driest month, with about 2 rainy days.

Is Naples busy at Christmas?

The street of nativity workshops, San Gregorio Armeno, is busiest from about late November to 6 January according to a travel blog. The city had not published official Christmas market dates when we checked. Pompeii and Herculaneum are closed on 25 December and 1 January, and the catacombs are closed on 25 December.

What is the best time to visit Naples and the Amalfi Coast?

May, June and September suit both, with warm days and a sea that is usually warm enough for boat trips. Travelmar boats from Salerno run all year, hydrofoils from Naples and Sorrento to Positano and Amalfi are described as running roughly April to October, and in 2026 the coast road had an alternate number-plate rule on every day in August and September. Check the operator before you book.
