Flounce Reef
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Flounce Reef offers some of Alaska's richest reef diving. Water ranges 5-15°C, warmest July, August, September.
Flounce Reef, tucked away in Alaska, offers a chilly but rewarding dive. We've found the best approach is to prepare for cooler temperatures and keep an eye out for nudibranchs clinging to the kelp. While not a coral reef in the tropical sense, the structure here provides habitat for various cold-water critters. This site is best for divers who enjoy macro life and don't mind a drysuit.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
