The millimeters of rain that fell on average between 1971 and 2000, in the various months of the year, in the cities of Bolzano, Genoa, Milan and Palermo. The summer months are those in which it rains less in the cities near the sea and it rains more in the mountain towns. In the plain cities the trend is intermediate. It rains less in the southern seaside towns. On the other hand, Genoa, as it should be known, has a high rainfall peak in autumn.
