Everything you need to know about this dive site.
Dive Site Overview
Portroe holds a compelling history, originally functioning as a slate mining operation before its transformation into a dedicated diving facility. For years, intrepid divers accessed this inland body of water unofficially, navigating through restricted areas, until it officially opened as a dive center five years ago.
This extensive freshwater reservoir now functions as a versatile training ground and recreational spot, accommodating everything from Open Water to Deep Specialty courses. Divers can explore its depths, which reach 40 m (131 ft), finding a meticulously arranged underwater landscape. Submerged objects, intended for both training and enjoyment, are scattered throughout.
Sturdy training platforms are among these, along with various containers, a distinctive mirror wall, and a unique diver's cave, offering varied navigational challenges. Multiple vehicles, such as cars, a truck chassis, and the significant wreck of a fire truck, provide interesting points of interest.
Being a freshwater environment, it provides a predictable and calm setting, free from tidal currents. Shore entry is via a convenient jetty with stairs, ensuring straightforward access for all levels of divers.
Well-equipped, the facility features amenities like a dive center, fill station, and gear-up banks, supporting full-day diving operations.

Best Time to Dive
Diving at Portroe is possible year-round, irrespective of external weather conditions. The primary factor influencing comfort will be the air temperature rather than sea state. During the cooler months, from January through March, average air temperatures range between 4.5-8°C (40-46°F), with rainfall averaging 3.2-3.5 mm. As spring progresses into May and June, temperatures climb to a more pleasant 13-15°C (55-59°F), and average rainfall decreases to 2.3-2.8 mm, potentially enhancing surface comfort before and after dives. Summer months, like July and August, maintain similar comfortable air temperatures around 15°C (59°F), though rainfall can sometimes increase slightly to 3.8 mm. Given its sheltered, contained nature, visibility typically remains consistent. Optimizing comfort, planning a dive during late spring or summer months provides the warmest ambient conditions on shore.
