Judd Rock
Why dive here
With 58+ marine species recorded in the area - including blue sharks, blue whales, humpback whales, orcas and seals & sea lions - Judd Rock offers some of Alaska's richest diving. Water ranges 5-15°C, warmest July, August, September.
Judd Rock, up in Alaska, can be a surprisingly engaging dive if you hit it right. We’ve found the rocky structure gives plenty of nooks and crannies to poke around. You'll likely spot some sizable sunflower stars clinging to the rocks and maybe even a red rock crab scuttling away as you approach. Keep an eye out for the slithery blackbelly eelpouts tucked into crevices. It’s a good spot for divers who enjoy taking their time and observing the smaller stuff, rather than looking for big pelagics.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
