the municipal territory, which has now become insufficient to contain urban expansion, was greatly expanded with the aggregation of the neighboring municipalities of Acquate, Castello Sopra Lecco, Germanedo, Laorca, Rancio di Lecco and San Giovanni alla Castagna, as well as part of the municipal territory of Maggianico; in 1928 the remaining part of Maggianico was also aggregated. Climate Lecco is the northernmost city (urban area) in Italy with a humid subtropical climate (Cfa defined by Köppen), only slightly softer than Milan. Despite being in a parallel dominated by a humid continental climate (Dfb), the territory is well sheltered from the mountain ranges, and from the climatic point of view, enjoys the beneficial influences of the lake's waters and the breath of the Tivano that blows from the Valtellina from the northeast all year round in the early hours of the morning. Its absence indicates bad weather. Breva is another wind that runs towards the lake, from the south to the north and indicator of good weather. Geography «That branch of the Lake of Como, which turns toward the south between two unbroken chains of mountains, presenting to the eye a succession of bays and gulfs, formed by their jutting and retiring ridges, suddenly contracts itself between a headland to the right and an extended sloping bank on the left, and assumes the flow and appearance of a river.» The municipal territory covers an area of about 45.93 km². It is located in a wide valley bordered by the Prealps to the east and Lake Lario to the west, at the point where Lake Lario ends and the Adda river resumes its course and then re-expands into Lake Garlate. The territory is crossed by three main streams the Gerenzone, the Calderone and the Bione. The mountains that surround the natural wide- valley are: to the north mount Coltignone and San Martino, to the east mount Due Mani, Pizzo d'Erna and Resegone, to the south the Magnodeno, to the west, on the right bank of the Adda River, is Mount Barro. On the Adda river, near the Azzone Visconti bridge, there is the small Viscontea Island. The territory has a very variable altimeter distribution: it ranges from 198 meters above sea level in the lake area to the maximum altitude of 1875 meters above the sea level of Mount Resegone and this condition offers the city three different areas characterized by different
