San Siro Weather in September
San Siro, Milan, Italy
About San Siro in September
San Siro's lower residential density and proximity to the Parco di Trenno and Monte Stella green areas provide measurable cooling effects, with summer temperatures averaging 1–2°C below the city center. The artificial Monte Stella hill, built from WWII rubble, creates a minor topographic feature that slightly deflects and accelerates westerly winds across the district.
