What Is The Coldest Month In Genoa?

Genoa, the coastal city in Liguria on the Ligurian Sea in north-west Italy, has a Mediterranean climate moderated by the water on one side and closed in by the Apennine hills on the other. The question of which month is the coolest has a clear answer in the official station record: January. The official 1971-2000 climate normals for Genoa Sestri, the Aeronautica Militare station at the airport west of the centre, put January's mean daily minimum at 5.5 C and its mean daily maximum at 11.5 C, the lowest pair of values in the whole monthly table. The figures below unpack what that means month by month, how much rain comes with the cold, and what a January visit actually involves on the ground.

What Is The Coldest Month In Genoa?

The coolest month in Genoa is January, with a mean daily maximum of 11.5 C and a mean daily minimum of 5.5 C, according to the official 1971-2000 climate normals for Genoa Sestri, the Aeronautica Militare station that serves as the city's reference. December and February sit just above it, at 12.5 and 6.5 C in December and 12.2 and 6.0 C in February. No month in the record drops below freezing on average.

Those three winter months cluster tightly, which is characteristic of a coastal Mediterranean station. The sea acts as a heat store, so the temperature falls slowly through December and January and rises equally slowly through February and March, with March already showing a mean high of 14.6 C. Anyone comparing Genoa with inland cities of the Po plain will notice the difference immediately: Genoa's winters are mild in the averages, even though the city sits much further north than Rome.

The station matters here. Genoa Sestri sits at the airport, about 7 km west of Piazza De Ferrari and 3 m above sea level, so the normals describe the coastal strip rather than the hillside suburbs above the city. Hill districts can run colder on any given night, but the published record that describes the city as a whole is this one.

The full monthly table comes from the same Aeronautica Militare CLINO 1971-2000 publication, and it carries a message that surprises first-time visitors: the coolest month is not the one with the most rainfall. October holds the highest monthly rain total at 171.3 mm, and November and January follow behind it. A January day at 11 C under clear sky feels entirely different from an October downpour at 20 C, and the planning consequences are different too. The wider weather picture, month by month, is covered in the site's Genoa weather guide.

How Cold Do Genoa Winters Get, Day And Night?

In January, the coolest month, Genoa's mean daily high is 11.5 C and its mean daily low is 5.5 C, per the official 1971-2000 normals for Genoa Sestri. That means afternoons typically sit around 11 or 12 C while nights fall toward 5 or 6 C. The normals give monthly means, not extremes, so individual nights can dip lower and individual afternoons can climb higher than the average.

Daytime in a Genoa January therefore reads like a mild spring day in much of northern Europe. The old town helps: the caruggi, the narrow medieval lanes of a historic centre the tourism office describes as one of the largest medieval historic centres in Europe at 113 hectares, are tightly built and shield much of the walking surface from wind. The Strade Nuove museums, the Palazzo Ducale exhibitions and the Aquarium of Genoa, open 365 days a year, all provide indoor hours at full schedule through the winter.

Night is when the cold registers. With the mean minimum at 5.5 C and the sea still relatively warm from summer, evening plans move indoors early. The Zecca-Righi funicular and the Castelletto Levante lift both run daily until 24:00, so an evening trip up to the Spianata Castelletto viewpoint is possible, with the obvious caveat that the terrace is warmer in the afternoon sun than after dark in January.

Packing follows from the numbers. Layers for 11 C afternoons, a real coat for 5 C evenings, and something water-resistant for the roughly 100 mm of rain the month brings. The question of how many days in Genoa is enough does not change with the season, but the pace does: winter itineraries reward a slower rhythm with longer museum stops.

How Much Rain Falls In The Coldest Months In Genoa?

January brings 101.8 mm of rain in the official 1971-2000 normals for Genoa Sestri, against December's 93.1 mm and February's 74.0 mm. July, at 24.2 mm with 2.8 rain days, is the month with the least rain in the record. October, not any winter month, records a rain total of 171.3 mm, followed by September at 136.4 mm, so a winter month takes only third place for rainfall in the year.

The pattern is autumn-wet, summer-dry, which is classic for the Ligurian coast. Rain arrives in concentrated Atlantic and Mediterranean systems rather than as continuous drizzle, and the steep hills behind the city can turn a modest rainfall into running water in the lower lanes. On a rainy January day the practical response is the same as in October: the covered itinerary. The caruggi, the Musei di Strada Nuova, the Galata Museo del Mare and Palazzo Ducale all keep visitors under roofs, and the site's guide to Genoa in the rain lists them in order.

Two details in the record are worth flagging for planning. First, the normals are 30-year averages: any single January can be drier or wetter than 101.8 mm, and the November figure of 108.8 mm shows how close the three cold-season months sit to each other. Second, rain totals say nothing about temperature, and the mild January means combine with the rain to produce the damp cold the city is known for in winter, a cold that feels sharper than the thermometer suggests because of the humidity off the Ligurian Sea.

Is January Still A Good Month To Visit Genoa?

Yes, and the climate record explains why: the coolest month still averages 11.5 C by day, all the major museums keep their published winter timetables, and the city's indoor density, from the Aquarium, open 365 days a year, to the covered old town lanes, makes a January visit workable in a way it would not in a colder inland city. The trade-off is about 101.8 mm of rain across the month, per the official normals for Genoa Sestri.

Winter timetable details matter more than the temperature. From 28 September 2026 to 18 April 2027 the Musei di Strada Nuova, Palazzo Rosso, Palazzo Bianco and Palazzo Doria-Tursi, open daily 10:00 to 18:30, with the one caveat that on Mondays only Palazzo Rosso can be visited. The combined ticket with the Museo di Sant'Agostino is 14 EUR full price, 9 EUR reduced, and the Genoa Museum Card costs 24 EUR for 24 hours or 45 EUR for 48 hours in the 2026 rates, covering 28 city museums. None of those prices changes with the season, which makes a cold-weather museum day straightforward to budget.

Getting around is equally season-proof. The AMT single ticket is 2.00 EUR for 110 minutes across the whole network, the metro runs its 7 km line from Brin to Brignole, and the airport link, the Volabus, uses the 10.00 EUR Met Daily ticket. The fixed airport taxi fare to the centre is 25 EUR per car. Weather never suspends any of these, so the transport plan for January is the transport plan for any month.

For travellers weighing the season, the comparison the site maintains on the best time to visit Genoa sets January against the spring and autumn alternatives, and the answer for cold-averse visitors usually lands on April or May, when the mean high climbs to 16.8 and 20.5 C. But January has its own case: the full monthly figures show a city that never averages below 5.5 C at night, and the things to do in Genoa do not shut down for winter. A guided introduction such as the Genoa intro walking tour covers the historic centre on foot, and its operator's live listing carries current dates through the winter, with Check availability showing the options.

One last seasonal note that the Genoa Travel Guide records elsewhere in detail: Genoa's event calendar does not pause in the cold. The Festival della Scienza ran 22 October to 1 November in 2026, the Salone Nautico occupied the fairgrounds 1 to 6 October 2026, and its 67th edition is set for 30 September to 5 October 2027. Winter dates for markets and smaller festivals appear on the city's own channels as they are confirmed, so a January trip is best booked with the museum timetables fixed and the event schedule checked closer to arrival.
