Lake Como and Lucerne
The verdict for September
Warm lake, easing crowds
+Warm weather and a quieter, relaxed pace.
–Occasional storms and weekend crowds.
September is a strong month: the lake is warm and summer crowds ease.
Warm and calm
+Settled weather and the best light.
–Rain returns by month end.
September is one of the best months: the lake is calmer, the light is soft and the festival's final concerts are on.
Scores and crowd levels are my own judgement; temperatures are monthly averages. Higher scores are better: quieter, cheaper and more pleasant.
Another month
