Habili Ali

Easternmost reef in St. John's, a flat-topped seamount with vertical walls, a grey reef shark cleaning station, and giant gorgonians on the west wall.

Last updated May 2026

The dive

Liveaboard zodiacs drop divers at the northwest corner first thing in the morning, where black-coral curtains hang from overhangs at around seven metres against the wall. The dive descends into the gorgonian field on the west side, an open spread of giant fans between thirty and forty-five metres anchored to the steep face, with longnose hawkfish perched in their branches. Working east the current strengthens, funnelling past the eastern tip where grey reef sharks visit the cleaning station; up to four have been reported together, though the encounter is a chance, not a fixture. Anthias swarm above the reef flat on the ascent. A second dive runs the southwestern side, dropping to twenty-five metres along a natural edge and tracking north for sharks before climbing to twelve metres to work four notches in the upper wall and finishing over the anemone field on the safety stop.

What makes it special

The Arabic word "habili" describes a reef that never breaks the surface, and Habili Ali barely does — its flat top sits at ankle depth in calm conditions and lifts only when small swell breaks over it. Below that thin crown, walls plunge vertically to about thirty-one metres before turning into a slope, with the seabed eventually bottoming near two hundred metres. The position is what sets the dive apart: easternmost reef in the St. John's system, forty-four kilometres from the Egyptian coast, at the boundary where the system ends and the open sea begins. That exposure draws current and pelagic chance the more sheltered reefs further west rarely see. The gorgonian field on the west wall is among the most striking in the Deep South, and on calm days the cleaning station on the eastern tip puts grey reef sharks within close range. Two recent first-person reports from elsewhere in the Deep South describe sustained bleaching across the region since late 2024, though neither names Habili Ali specifically; one professional July 2025 account still calls the structure here a feast for the eyes.

Know before you go

Currents define every dive at Habili Ali. They shift direction without much warning, and the operator-recommended pattern is a current test before entry and a willingness to play with depth to find the right contour line, since the current can reverse against you after the first third of the north wall. The shallow reef top creates breakers in moderate swell, and the boat's call is the deciding one — Habili Ali is a "weather permitting" stop on most St. John's itineraries, and cancellations are part of the Deep South experience. When conditions align, it pays to be in the first group underwater, before multiple liveaboards converge on the moorings on the southern side. Night diving is not possible — the exposed location offers no safe mooring after dark.

Frequently Asked Questions

What sharks can I see at Habili Ali?
Grey reef sharks are the most consistent encounter, with a cleaning station at the eastern tip and patrols on both eastern and western edges. Up to four together has been reported. Silvertips, silkies, and hammerheads also appear but are less predictable. Look into the blue past the reef edge for passing pelagics.
How do you get to Habili Ali?
Liveaboard only. The reef sits 44 km from the Egyptian coast in the St. John's system, near the Sudanese border. Boats depart from Port Ghalib (about an 11-hour transit) or Hamata on Deep South itineraries of 6-7 days. Calm weather is required to approach, so cancellations are part of the plan.
Is Habili Ali suitable for beginners?
No. Strong, variable currents, depths beyond recreational limits, and surface conditions that can include surge over the reef top make this an advanced dive. AOW certification and current-diving experience are the minimum, and guides run a current test before every descent.
When is the best time to dive Habili Ali?
May to October offers the warmest water (29-31 C surface) and the calmest seas for approaching this exposed reef. The site is on Deep South itineraries year-round, but the weather window decides whether boats can actually moor and dive.
What depth do you dive at Habili Ali?
The reef top sits at near-surface level, dropping in places to ankle depth in calm conditions. Most diving runs the walls between 15 and 35 m. The gorgonian field on the west occupies 30-45 m. The seabed drops to 200 m, far beyond recreational range.
How is the coral after the recent Red Sea bleaching?
Recent first-person accounts of the Deep South region describe bleaching and reef decline since late 2024. A July 2025 trip report still framed Habili Ali as compelling from a structure perspective. None of the recent regional reports name Habili Ali specifically, so the 2026 condition of the gorgonian field and black-coral curtains is uncertain.
What makes Habili Ali different from other St. John's sites?
It is the easternmost reef in the system, alone at the open-sea boundary. That position brings stronger currents and richer pelagic chance than the more sheltered St. John's reefs further west. The gorgonian field at 30-45 m and the black-coral curtains from 7 m are features the neighbouring reefs do not match.
