About Duomo in September
Milan's historic core around the Duomo is the epicenter of the city's urban heat island — dense stone and marble facades, heavy pedestrian traffic, and minimal tree cover keep nighttime temperatures 3–5°C above suburban areas. The narrow medieval streets limit airflow, trapping summer heat and winter fog in equal measure.
