Bloody Bay, Little Cayman tide times

The Bloody Bay Wall begins at the reef lip at 6 to 8 metres depth and drops vertically to approximately 1,800 metres. The sport diving range of the wall — the zone covered by recreational divers with standard certification — runs from the lip at 8 metres to the beginning of decompression territory at around 40 metres. The most visually rewarding zone is 15 to 30 metres, where the big sea fans and black coral begin and the wall face is most vertical. Technical and rebreather diving to 60 metres and below is operated by the specialised dive operators on Little Cayman with appropriate certification requirements.

The reef flat between the shore and the wall lip at 6 to 8 metres depth is excellent snorkelling territory. The reef flat runs 3 to 6 metres depth, with healthy staghorn and brain coral, dense reef fish populations, tarpon, and occasional eagle rays. The wall lip itself is reachable by snorkel — approximately 10 minutes swimming from the beach — and the view from the surface over the 1,800-metre drop is dramatic in clear visibility. Snorkellers at the wall edge should go in buddy pairs, carry a surface marker buoy, and be comfortable in open deep water.

Mixed semidiurnal, spring range roughly 0.4 to 0.6 metres. The current along the Bloody Bay Wall face runs at 0.2 to 0.5 knots on a typical day — mild enough for most recreational divers, but the stronger current windows require drift-dive technique. The ebb current runs west along the north coast; the flood runs east. Dive operators on Little Cayman plan the guided dives around the current cycle and run live-boat pickups for the drift dive sites.

For the Cayman Islands, the Cayman Islands Meteorological Service publishes weather and marine forecasts. The nearest authoritative tide gauge reference is at George Town, Grand Cayman; Little Cayman runs on a similar tidal phase with a small offset for the approximately 80 km distance.

No. The reef system along Little Cayman's north coast and the Bloody Bay Marine Park boundaries require current chart data from the Caribbean Hydrographic Institute for vessel navigation. The mooring buoy positions do not substitute for full chart navigation of the approach. For any vessel entering Little Cayman waters, the Cayman Islands Port Authority and the current Caribbean charts are the authoritative references. Open-Meteo Marine gridded predictions are not authoritative navigational data.
