Everything you need to know about this dive site.
Dive Site Overview
An artificial reef, Rube Allyn Reef was established through a thoughtful initiative focused on marine conservation and recreational development. Its creation involved the deliberate sinking of various purpose-built and repurposed materials, all meticulously designed to mimic natural reef formations and functions.
These structures provide essential new habitat in areas previously lacking complex underwater environments, actively fostering biodiversity and sustaining marine ecosystems. Initial deployment aimed to serve as an accessible dive destination for certified divers, offering both ecological value and recreational interest. Since its strategic placement, the reef has progressively evolved, accumulating significant marine growth and attracting a diverse variety of inhabitants as it adapts and integrates into its submerged surroundings.
Divers exploring the site will typically find depths up to 20-30 meters (65-100 ft), making it suitable for a broad range of certified divers, from those recently certified in open water to more experienced advanced divers. Observing this ongoing development offers insight into ecological succession within an artificial environment.
Continuing maintenance and development efforts further augment marine life, providing consistent opportunities for underwater exploration, education, and study.

Best Time to Dive
For an optimal dive experience at Rube Allyn Reef, consider planning your trip between late spring and early fall. Months like May, June, July, and September consistently register "Good" dive scores, indicating favorable overall conditions. During these periods, air temperatures are comfortably warm, ranging from 25.5°C (78°F) in May to 29°C (84°F) in August, making surface intervals pleasant. While August and September see slightly higher average rainfall, it's often transient and usually doesn't significantly impact underwater visibility. Conditions generally include lower wave heights and reduced wind speeds, contributing to calmer seas and better boat access. Even October and November offer good dive scores with air temperatures still around 21-24°C (70-75°F), providing a comfortable, less crowded option.

Dive Experience & Conditions
Beginning your descent at Rube Allyn Reef, divers will notice the water column's clarity can vary, depending on recent weather patterns and tidal movements. Visibility is typically good, allowing divers to appreciate the reef's structure as they approach it. Water temperatures are not consistently reported in available data but are generally comfortable for the region; most divers find a 3-5mm wetsuit suitable for extended bottom times. Expect to find the main reef structures rising from the seafloor, which generally lies at depths up to 30 m (100 ft). Currents are usually mild but can occasionally pick up, especially during tidal changes, so paying attention to local conditions is advisable. The structural diversity of the artificial reef creates numerous swim-throughs and sheltered nooks, which can be explored leisurely without excessive current. Divers can navigate along the various components, observing the established marine life.
Dive Difficulty & Safety Guidelines
Approaching Rube Allyn Reef requires careful attention to responsible diving practices, particularly due to its status as an artificial reef with varying structural integrity over time. Divers should maintain neutral buoyancy to avoid contact with the reef components, protecting both themselves and the delicate marine growth. Awareness of depth limits, particularly the maximum recreational depth, is crucial, as is careful gas management for the planned dive profile. Always dive within the limits of your certification and experience. Operators typically provide detailed briefings on specific entry and exit procedures, current conditions, and any known temporary hazards. A surface marker buoy (SMB) is recommended for all dives, especially if there is potential for boat traffic or varying surface conditions.
