La Digue offers a varied mix of reef, drift, pinnacle and canyon sites spread across the island and its neighbouring outcrops. Hawksbill Sea Turtle and Spotted Eagle Ray are observed across virtually every site, while Whitetip Reef Shark and Great Barracuda add interest at depth. Shore entries at spots like Anse Sévère suit beginners, while boat-access sites such as South Mariane Island challenge advanced divers with complex topography. Conditions peak in spring and again in October and November.
Monthly water temperature across La Digue's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water is warmest from March to May and cools noticeably through the mid-year months, with August being the coolest point in the cycle. The best-rated diving months cluster in spring and again in October and November, suggesting that calmer, clearer conditions bookend the cooler mid-year period. Drift sites like Sister Bank and Channel Rock are more current-dependent, so timing dives with slack water matters on those exposed passages.
