Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Descending into the waters above Rube Allyn Reef provides an immediate sense of purpose, as divers approach a substantial artificial structure situated to enhance marine habitat and recreational diving opportunities. Typically, the site lies within common recreational diving depths, ranging from shallower sections to a maximum depth that can extend to around 30 m (100 ft), though depths vary based on the specific structures.
Air temperatures generally range from 16°C (61°F) in February to 29°C (84°F) in August, influencing topside comfort more than underwater conditions. Average wave heights frequently remain below 1 meter (3 feet), especially from May through September, contributing to more stable boat conditions. Wind speeds vary, but generally fall between 21 and 33 km/h (13-21 mph), which can impact surface chop.
Rain levels are typically low, with August sometimes seeing higher averages around 8 mm (0.3 inches). Diving involves navigating the various components of the artificial reef, offering numerous nooks and crannies for exploration.
