Halftide Reef
Why dive here
With 35+ marine species recorded in the area - including humpback whales, orcas and seals & sea lions - Halftide Reef offers some of Pacific Northwest's richest reef diving. Water ranges 7-17°C, warmest July, August, September.
Halftide Reef is what we'd call a solid Pacific Northwest dive – reliable, if not flashy. You're mostly looking at rock walls covered in anemones and sponges, with a fair number of Pacific Northwest usual suspects making an appearance. We’ve spotted plenty of spotted ratfish hanging around, and the occasional Dungeness crab scuttling past. It’s a good spot for a relaxed dive, maybe a second tank of the day, with a focus on macro life if you’re patient. Definitely suits divers who appreciate the subtler beauty of a temperate reef.
Safety Notes
Cold water this month (avg 11°C). Drysuit or thick wetsuit (7mm+) recommended.
