Rome and Milan
The verdict for September
Summer ease returns
+Temperatures become more comfortable while summer conditions largely remain.
–Demand remains strong, especially in the first half of the month.
Late September is many Romans' favourite time of year.
Best overall month—fashion, weather, crowds, value all balance
+The best all-round month: warm, clear, energised and far calmer than summer.
–Fashion Week week itself books out early.
September is a peak month. Weather transitions from summer to autumn—perfect. Fashion Week brings energy and events. Tourist numbers drop significantly. Prices drop from July-August highs.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
Another month
