About Centro Storico in September
The Centro Storico's dense matrix of stone palazzi, narrow cobblestone streets, and minimal green space creates Rome's most intense urban heat island, with nighttime summer temperatures regularly 5–6°C above suburban areas. The lack of ventilation corridors means sea breezes from the Tyrrhenian rarely penetrate this district, trapping heat and humidity in the ancient street grid.
