, with mild and rainy winters, and hot and sunny summers. The city is located in northern Italy, but on the coast, and it's clearly separated from the Po Valley by the Apennines, so along with the rest of the Ligurian Riviera it has a much milder climate.
is quite frequent, since in periods of bad weather a depression often forms right on the Gulf of Genoa, which draws to the city a moderate or strong northeast wind, able to lower the temperature.

in Genoa are quite abundant, given that they exceed 1,000 millimetres per year; in particular autumn is very rainy, when the sea is still warm, and the first disturbances are capable of causing heavy rains, which in turn can lead to flooding of the streams coming down from the Apennines and passing through the city, especially in late September and in October. October is the wettest month, with as many as 170 mm on average. Summer is the driest season, but only in July, when the disturbances are rarer, precipitation falls below 30 mm.

, from December to February, is mild; in particular, periods of good weather are pleasant, when the sun shines, while the Po Valley is shrouded in fog. Instead, in periods of bad weather, with the wind from the north-east, the cold air of the Po Valley manages to climb over the Apennines and gets to the city, so that you can have cold and rainy days. In colder periods, still for the same reason, it may even snow, although the snow tends to melt quickly, because the seaside location makes frosts rare, and in any case light.
, from March to May, is mild and gradually becomes more sunny, but it is also quite rainy. March and the first half of April are unstable periods, in which the first mild and sunny days alternate with colder and rainy days. In April and May, while in the rest of Italy the first very mild days occur, with highs above 20 degrees, sometimes on the Ligurian coast a layer of clouds can form, able to keep the temperature cool, around 15 °C even during the day.
, from June to August, is hot and sunny. Generally the heat is not excessive, thanks to the influence of the sea and the breeze, but you can not rule out some particularly sultry periods. Some disturbances may also pass in the summer, especially in June and in late August, while on sunny days some thunderstorms may reach the coast from the interior.
, from September to November, is mild and humid, with sunny days, but also periods of bad weather, in which as we have said it can rain a lot.

When to go
The best times
to visit Genoa are spring and early summer, in particular from mid-April to mid-June. Also September is a good month, especially in the first half, because then the risk of heavy rainfalls increases.
In the height of summer, in July and August it can be hot, although less frequently than in other parts of Italy.
For a beach holiday on the Ligurian Riviera, the best months are just July and August.
