Optimal Diving Seasons

Peak Seasons

The best three months for diving in Ustica Island are typically June, July, and August. During these months, the water temperature is warm, ranging from 23°C to 27°C (73°F to 81°F), providing comfortable diving conditions. Visibility is also at its peak, often reaching up to 30 meters (98 feet) or more. Marine life is abundant, and the chances of encountering a variety of species are higher. The weather during these months is generally sunny and stable, making it an excellent time for divers to explore the vibrant underwater world of Ustica Island.

Off-Peak Seasons

Diving during the off-peak seasons, namely the months of March to May and September to November, has its pros and cons. On the positive side, these months often see fewer tourists and divers, which means less crowded dive sites and a more serene experience. The water temperature during these times ranges from 15°C to 22°C (59°F to 72°F), which might be slightly cooler but still manageable with the right wetsuit. However, visibility might not be as consistently clear as during the summer months, varying between 15 to 25 meters (49 to 82 feet). Additionally, the weather can be more unpredictable, with occasional rain and wind affecting dive conditions. Divers should be prepared for variable conditions and check local forecasts and dive reports before planning their trips.
