Best Time for Diving and Essential Planning Tips

July and August offer warmest conditions but busier sites; June and September provide ideal balance of pleasant temperatures and fewer crowds. All PADI, SSI, and CMAS certification levels are welcomed, with numerous sites suitable for beginners in shallow bays near Porticcio. A 3mm wetsuit suffices in summer; 5-7mm recommended for spring, autumn, and winter diving. Advanced booking is essential during peak season (July-August), whilst walk-ins are generally accepted in shoulder months.

Ajaccio's Unique Marine Life and Underwater Landscapes
Ajaccio's underwater environment showcases classic Mediterranean biodiversity within dramatic granite formations unique to Corsica's coastline. Divers regularly encounter dusky groupers, octopuses, conger eels, and colourful nudibranchs amongst Posidonia seagrass meadows. The rocky reefs burst with life including scorpionfish, rainbow wrasse, and damselfish, whilst lucky divers spot eagle rays and barracuda in open water. The famous red coral (Corallium rubrum) thrives on deeper walls, though collection is strictly prohibited. Ajaccio's proximity to the Scandola Reserve means biodiversity here benefits from spillover effects. Underwater caves and swim-throughs carved into granite cliffs provide thrilling exploration, particularly at sites like Punta di Sette Nave. Visibility consistently exceeds 20 metres, often reaching 40 metres in summer, revealing the stunning topography of drop-offs, plateaus, and underwater canyons characteristic of this pristine coastline.
