About June Jones Reef
June Jones Reef is an intriguing dive site in Portugal, featuring the scattered remains of a 50-foot steel boat that succumbed to severe storms. This site combines both wreck and natural reef characteristics, making it a compelling destination for divers interested in exploring marine life amidst historical structures. The vessel's debris is widely spread across the seabed, creating multiple small ecosystems where marine life thrives, offering divers new discoveries with each visit to its various 'mounds of debris'. While the specific topography beyond the wreck is implied to be a reef environment, the exact depth ranges and geological formations are not detailed, but the scattered nature of the wreck creates an irregular, varied seabed. Marine life sightings here are often characteristic of the broader region, including larger pelagic species such as sharks, whales, dolphins, and turtles, indicating a site that may attract significant oceanic fauna. The presence of these animals suggests diverse ecological conditions, even if the primary draw is the wreck itself. Diving here involves navigating the dispersed sections of the steel boat. Divers should anticipate a search-and-explore approach, as the description emphasizes looking around each debris mound to uncover its "secrets." This implies a dive profile focused on detailed examination rather than a single, large structure, requiring attentive exploration to appreciate the full extent of the site.

Conditions & Currents
Information on currents specifically at June Jones Reef is not available in the provided sources. However, divers should always anticipate varying current strengths at any open ocean dive site. General diving safety guidelines emphasize assessing weather conditions, including swell and sea state, before diving, as these factors significantly impact diver location and safety at the surface. Dive briefings should always include details on potential currents to prevent diver separation. Prudent planning for entry and exit, especially from a boat, is essential. Visibility can fluctuate, and thermoclines may be present depending on the season and specific location within Portugal's diverse marine environment.
Marine life & sighting chances
Dive profile & how the dive runs
Divers typically access June Jones Reef by boat, given its location offshore. The dive begins with an entry directly over the wreck's general vicinity. Due to the widely dispersed nature of the 50-foot steel boat, the dive profile involves exploring various mounds of debris and scattered sections of the wreck. Divers often navigate by following the contours of these underwater structures, searching for marine life that congregates around the shelter and hard surfaces. The route is flexible, allowing for discovery of the "secrets" within each section. Depths will vary depending on the specific scattered components of the wreck. The dive concludes with a gradual ascent, allowing for a safety stop, usually in the shallower parts of the reef or open water near the boat, before surfacing for pickup.
Underwater photography
To capture the widely dispersed elements of the June Jones Reef wreck, a wide-angle lens would be suitable for overall scenes, showcasing the scattered debris and the general topography. For capturing the smaller secrets within the wreckage, such as resident fish or invertebrates, a macro lens would be more appropriate. Given the potential for variable visibility common in many temperate waters, strobes are highly recommended to bring out color and detail, especially in the shadowed areas of the wreck. Maintaining excellent buoyancy control is crucial to avoid stirring up sediment from the wreck and surrounding seabed, which could degrade photographic opportunities. Approach marine life gently and respectfully, allowing them to remain undisturbed while you capture their images within the wreck environment.

June Jones Reef is one of Portugal's signature dive sites. A liveaboard sleeps you on the water and puts you in the water for three to four guided dives per day, including dawn and night dives that day-boat operators rarely offer. You skip the daily commute back to port and reach quieter, less-crowded sites in the same region on a single trip.
