Positano in October

May and September are the sweet spots - warm enough for swimming, cool enough for walking, and half the crowds of summer. June gets busy but the weather's perfect. July and August turn Positano into a beautiful sardine can where dinner reservations book weeks ahead. October still works if you don't mind cooler water and the occasional rainy day. April can be lovely but unpredictable - you might get 25°C sunshine or 15°C clouds. Winter? Most restaurants close, boats stop running, and you'll have the place to yourself - which sounds romantic until you realize why everyone leaves. The shoulder seasons give you Instagram-worthy shots without fighting tourists for the perfect angle.
