September is very-high for Positano.
September is one of the best months on the Amalfi Coast — still warm and sunny, the sea still warm, but with the August crush easing. It averages 27°C/18°C with about 70mm of rain over 6 days.
The sea stays warm (around 25°C) well into the month, so swimming, boat trips, and beach days continue, while the heat eases enough to make the Path of the Gods comfortable again. Everything is still open and lively, and the hills carry the grape and lemon harvest.

Positano in September — Full Picture
September is one of the best months on the Amalfi Coast — still warm and sunny, the sea still warm, but with the August crush easing. It averages 27°C/18°C with about 70mm of rain over 6 days.
The sea stays warm (around 25°C) well into the month, so swimming, boat trips, and beach days continue, while the heat eases enough to make the Path of the Gods comfortable again. Everything is still open and lively, and the hills carry the grape and lemon harvest.
Crowds and prices ease from the August peak through the month, especially late September, making it better value with more breathing room — a favourite among repeat visitors. Early September is still busy and pricey, closer to August.
Rainfall ticks up a little versus mid-summer, with the odd autumn shower or thunderstorm, but most days are fine. For the combination of warm seas, good weather, openness, and easing crowds, September rivals May as the prime time to visit.
