About Concrete Block Reef
A reef dive. It goes down to 18 m. You get in from a boat. It suits Advanced divers and up, as a dive guide states it. The coast faces W: swell from the W reaches it, and wind from the E blows out to sea. No dive centre within 10 km, the nearest 21 km away. The sea is about 7°C in January, its coldest month (drysuit), and 19°C in August, its warmest (7 mm wetsuit and hood). The town to stay in is Squamish. Within 5 km we also list 3 dive sites and 2 climbing areas.
