September in Sorrento offers a transition from the peak summer heat to a milder, more comfortable climate. Typical conditions include warm, sunny days with average high temperatures in the low to mid 20s Celsius (mid 70s Fahrenheit). Sea temperatures remain pleasant, making swimming and other water activities still enjoyable. Rainfall is relatively low compared to the later autumn and winter months.
This period is often considered an ideal time to visit Sorrento. The slightly cooler temperatures make exploring the town, hiking the surrounding hills, or visiting nearby attractions like Pompeii and Herculaneum more comfortable. The sea is still warm enough for swimming, and the beaches are less crowded than in July and August. Historically, September has marked the beginning of the grape harvest, offering opportunities to experience local traditions and enjoy the region’s renowned wines.
