The best time to visit Milan is April, May, June, September and October, when average highs sit in the comfortable low-20s to high-20s °C and the city is pleasant for exploring the Duomo and its piazzas on foot. April brings highs around 19 °C with 9 rain days, while September averages 24 °C with 10 rain days, striking a fine balance of warmth and manageable rainfall. July and August are peak season, when highs climb near 30 °C and school-holiday crowds and prices swell. Winter (December to February) is the quiet, low season, cold and grey but calm for those who prefer fewer visitors.

How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.
