Why dive here
With 169+ marine species recorded in the area - including dolphins, dwarf minke whales, humpback whales, ocean sunfish (mola mola) and octopuses - Square rock offers some of West Coast's richest diving. Water ranges 8-17°C, warmest July, August, September.
Square Rock, off Ireland's West Coast, gives you a classic Atlantic rocky dive. You’ll weave around boulders and explore crevices, spotting various temperate species like wrasse and gobies amongst the kelp. It’s a good choice for divers looking for a straightforward shore dive, with conditions often calmer than exposed headlands. We'd suggest it for an easy second dive or for newer divers getting comfortable with Irish waters.
Safety Notes
Cold water this month (avg 14°C). Drysuit or thick wetsuit (7mm+) recommended.
