September is Sicily’s second summer. 22–30°C, sea at 25–27°C (warmer than June), Italian families back at school, and the vendemmia (grape harvest) in full swing.
Plan this trip →The best month. Heat eases from August’s extremes. Beaches empty after Sept 10 (Italian school starts). Etna vineyards in harvest (Nerello Mascalese picking). Granita still flowing. Prices dropping. Cous Cous Fest (San Vito Lo Capo, last week of September): international couscous championship on a perfect beach.
Shoulder by mid-Sept. Hotels €50–100/night after Sept 15 (vs. €80–150 in Aug). Flights drop 30–40%.
