Tatnall Reefs
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Tatnall Reefs offers some of Alaska's richest reef diving. Water ranges 5-15°C, warmest July, August, September.
The Tatnall Reefs offer a taste of colder water diving, a stark contrast to tropical sites. Here, we expect to find a rugged reef structure, likely home to species adapted to these northern waters. Think anemones, sea stars, and various rockfish sheltering in crevices. This site is probably best suited for experienced cold-water divers keen on exploring a less-travelled region.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
