Port St Johns Grounds
A profundidade indica a faixa desde o topo do ponto até o seu máximo habitual; a "certificação recomendada" é o nível das agências convencionais que os operadores costumam exigir, não uma exigência legal. Correntes e visibilidade mudam diariamente — trate tudo aqui como referências de planejamento.
Port St Johns is the sardine run's capital: the shelf narrows here, pushing the migrating shoals — and everything eating them — into a workable band close to the cliffs. June and July mornings start with a launch through the river mouth or surf, then hours of reading gannet flight lines and dolphin spray until a bait ball forms. When one does, swimmers slide in on snorkel first; scuba follows only if the ball stabilizes. Common dolphins arrive in the hundreds, copper sharks carve the sphere, gannets hit like hail, and Bryde's whales end arguments in one lunge. Blank days are part of the honest arithmetic.
O momento pelo qual você vem: The highest-probability staging area for full bait-ball events
Topografia: Open shelf water off the Mzimvubu River mouth; action is midwater and surface, not on the seabed
Corrente: The Agulhas edge, counter-currents, and cold pulses all meet here; every day is read fresh from water temperature and bird behavior.
Sabe antes de entrar na água
Perigos: Cold water, long rough days, surf and river-mouth launches, and feeding predators at close quarters — obey the divemaster instantly.
Conservação: Boats and swimmers work under permit conditions; crews coordinate on the radio so bait balls are not mobbed by every operator at once.
