Traveller notes on Positano in September
Notes from nearby Capri (24 km away)
Positano doesn't have its own notes for September yet — these are about Capri, close enough to share the season.
September on Capri is still swimming weather — the forum puts the sea around 25°C and posters report getting in the water on every September trip unless it was actually raining. Shorts by day, a light jacket or sweater in the evening once the air eases back from a high near 24°C. On crowds it's a month of two halves: the island is packed daily from mid-June to early September, then late September thins noticeably, and weekday day-trips stay quiet because local day-trippers come mainly at weekends. One local caution — jellyfish turn up some years and have been exceptionally bad in a few; beach clubs keep sting spray.
Other months in Positano
Positano's forum calls July hot, around 84°F on average, warm rather than scorching but genuinely more intense with the coast's humidity added in. Regulars flag mosquitoes as worth planning around if the room doesn't have proper air conditioning, and note July is the Amalfi Coast's most crowded month, though there's still room to escape the crowds if you look.
