The Portofino promontory is one of the top scuba diving destinations in the Mediterranean, known for exceptional marine biodiversity and dramatic underwater scenery. Extending into the Ligurian Sea, its unique coastline captures nutrient-rich currents that sustain vibrant reefs and dense marine life. Protected within the Portofino Marine Protected Area, divers explore colourful walls, pinnacles, caves, and historic shipwrecks. With over 20 dive sites suitable for beginners and experienced divers alike, Portofino offers some of the most rewarding and scenic diving in Italy year-round.
Water temperatures in Portofino range from approximately 18°C in May to peak summer averages of 26–27°C between late August and early September, making it one of the warmest Mediterranean diving periods.
Visibility in the Ligurian Sea can vary depending on sea conditions, including waves, currents, and seasonal rainfall. During the summer diving season, average underwater visibility typically ranges between 15–20 metres. However, it may decrease to under 10 metres after storms or strong currents, while exceptional weather conditions can extend visibility to 25 metres, offering outstanding scuba diving clarity.
