Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
What initially appears as a straightforward sandy bottom dive at Long Beach quickly transitions into a surprisingly intricate underwater landscape. From the shore, the bottom gradually shelves, reaching approximately 5 m (16 ft) relatively close in and extending to a maximum depth of 18 m (60 ft) near the Simon's Town Harbour mouth.
Divers exploring the initial sandy stretches will soon discover scattered wreckage and artificial reef structures. A prominent barge wreck serves as a focal point, having become encrusted with seaweeds and providing vital shelter for numerous fish species. Nearby, a pipeline also supports a variety of sessile growth.
For those willing to venture further, seldom-visited areas hold a smaller artificial reef, an additional wreck approximately 160 metres (525 ft) southeast of the slipway, large anchor chains, a massive anchor, concrete blocks, and parts of wrecked fishing boats. These features create a habitat for diverse marine life, transforming what some consider merely a training ground into a rewarding site for seasoned explorers.
Its accessibility makes it popular for skill development, but the detailed structures reward persistent and observant divers seeking more than the usual.

Best Time to Dive
Planning a dive at Long Beach means navigating variable seasonal conditions, even though the harbour shape offers protection from localized winds and waves. While general dive scores tend to be moderate (April-May) or poor (most other months), this often reflects broader regional weather. Air temperatures are warmest from December through February, averaging around 20-21°C (68-70°F), with minimal rain. In contrast, winter months like July and August see cooler air temperatures of approximately 13°C (55°F) and higher rainfall, coupled with significantly increased wave heights, potentially impacting overall access or comfort. Water temperature isn't consistently reported across the year, but it varies depending on oceanic upwelling and seasonal changes, often cooler than expected due to local currents.

Dive Experience & Conditions
Beneath the surface, the site's unique harbor shape moderates exposure to most winds and waves, creating generally calm and flat water conditions, particularly near shore. This contributes to Long Beach's reputation as an easy shore dive, ideal for training and less experienced divers. Visibility at the site can fluctuate, sometimes offering exceptionally clear conditions, while at other times it might be reduced depending on recent weather and sediment movement. Water temperatures aren't consistently reported, but divers should anticipate cooler conditions typical of South African waters, requiring appropriate thermal protection. The gradual slope and the presence of scattered debris and wrecks provide structure for marine life and make for an engaging, albeit moderate, underwater experience.
Dive Difficulty & Safety Guidelines
Navigating Long Beach requires awareness of several factors to ensure a safe dive. Box jellyfish have been observed here, so vigilance is necessary, particularly when conditions are calm. Although sharks are rarely found, it's always prudent to maintain situational awareness. An MPA (Marine Protected Area) permit is mandatory for diving at this site. Divers should also be aware that the area is relatively close to the Simon's Town Naval Base; occasionally, for security reasons, access to the site may be temporarily closed when foreign warships are present. Always confirm current access status before planning your dive. Easy shore entry and exit minimize surface complications.

Marine Life at Long Beach
Upon entering the water, divers often spot a fascinating array of smaller marine species residing among the scattered wreckage and artificial structures. Expect to encounter pineapple fish, crown crabs, and agile klipfish. Look for blue fin gurnards foraging on the sandy bottom and shaggy sea hares grazing on the sessile growth. Biscuit skates and stingrays are frequently observed gliding across the sand, while sea squirts cling to surfaces. Octopus are common inhabitants, often camouflaged within the nooks of the barge wreck or pipeline. Occasional sightings of John Dory and other fish not typically found in the immediate region add to the site's appeal, indicating a surprising biodiversity for those taking the time to explore beyond the obvious.
