Dive Site Characteristics
Key Dive Site Facts
Dive Site Overview
Glen Ayr's underwater landscape distinctly divides into two primary exploration zones, each offering a unique dive experience. North of the dock, divers will discover an impressive wall that descends sharply, reaching depths of 30 m (100 ft) or more.
This vertical face provides a challenging yet rewarding environment, particularly for advanced and technical divers keen on navigating deeper contours and exploring potential overhangs or crevices. Exploring its considerable length offers a sense of profound depth characteristic of the Hood Canal's fjord environment. Conversely, the areas immediately south of the dock transition into an expansive rubble field.
This shallower zone, generally remaining above 15 m (50 ft), is ideal for Open Water divers, offering ample opportunity for skill refinement and detailed observation. Its varied substrate—composed of rocks, shells, and detritus—creates numerous microhabitats perfect for macro photography enthusiasts searching for small, intricate marine life.
The site's inherent duality ensures a broad appeal; whether one seeks the thrill of a deep wall dive or the leisurely pace of a shallow critter hunt, Glen Ayr provides varied opportunities. Divers can easily spend a full day exploring both facets without feeling they've seen everything.
Best Time to Dive
Planning a dive at Glen Ayr benefits from understanding the seasonal climate patterns, particularly the warmer, drier summer months. July typically presents the most favorable conditions, with average air temperatures peaking around 19.98°C (67.96°F) and minimal rainfall, averaging just 0.17 mm. Spring and early autumn also offer good opportunities, as air temperatures remain pleasant, ranging from 9.31°C (48.76°F) in April to 16.42°C (61.56°F) in September. During these periods, rainfall is generally low, contributing to better visibility and a more comfortable topside experience. Winter months, while still rated as 'Good' for diving, see air temperatures drop to around 4.48-6.49°C (40-44°F) with significantly higher rainfall, reaching up to 11.26 mm in December.

Dive Experience & Conditions
Accessing the water at Glen Ayr is convenient, with options for both shore and boat entry, allowing for flexible dive planning. Once submerged, divers will encounter conditions typical of a cold-water environment, which is not consistently reported but implied by recommended gear. The site caters to a wide range of certifications, from Open Water to Advanced. Shallower sections around 6 m (20 ft) are manageable for beginners, while the deeper wall to 40 m (130 ft) requires advanced training and proper cold-water equipment. Currents can vary, so assessing local conditions before entry is always advisable. Underwater visibility, like many fjord dives, depends on recent weather and marine activity.
Dive Difficulty & Safety Guidelines
Diving at Glen Ayr requires divers to possess an appropriate certification level for their intended depth, given the site's varied profile. Beginners can explore the shallower rubble fields, but those venturing to the 30 m (100 ft) wall sections should be Advanced Open Water certified or higher. It's important to monitor dive computer readings closely, especially when exploring deeper sections, to manage no-decompression limits. While no specific site hazards are consistently reported in available data, divers should always practice safe diving protocols, including buddy system adherence and proper ascent rates. Keep an eye on local conditions, as currents can be present.

Recommended Dive Suit
Because recent water temperature readings are not available for Glen Ayr, the guidance below is based mainly on current air conditions and seasonal expectations. Current surface air temperatures are roughly 17°C (62°F).
Based on regional estimates and current weather, the likely required exposure protection is a 5mm or thicker wetsuit. Note that local currents and upwellings can alter this. A hood or vest is suggested for sensitive divers due to surface winds. A thermal robe or jacket is recommended between dives.
Weather patterns are currently shifting, so expect some variability in conditions. A significant temperature drop is forecast; strongly suggest bringing a backup warmer suit option. Some divers prefer carrying a slightly thicker suit as a backup.
