Why dive here
With 35+ marine species recorded in the area - including nurse sharks - Cedar Island Ledge offers some of New England's richest diving. Water ranges 4-19°C, warmest July, August, September.
Cedar Island Ledge offers a typical New England dive. You'll likely find lobster and crabs tucked into the rocky crevices, along with cunner and sculpin hovering near the bottom. It's a decent spot for a shore dive when conditions are calm, best suited for divers looking for a relaxed local outing rather than big pelagics or vibrant corals. Visibility can be a gamble, but on a good day, it’s a pleasant enough rummage around.
Safety Notes
Cold water this month (avg 15°C). Drysuit or thick wetsuit (7mm+) recommended.
