Red Sea Deep Dive: The Challenging Passage North
The Red Sea has humbled blue-water sailors for centuries. Merchant dhows once spent months beating northward in short tacks, hugging the Egyptian coast or the Arabian shore in search of a favourable slant. Modern yachts fare better with diesel engines and accurate wind forecasts, but the fundamental challenge remains: the prevailing north-northwesterly wind funnels relentlessly down this narrow, elongated sea at 20 to 30 knots for much of the year, dead on the nose of anyone bound for Suez. Add coral-studded shallows, shipping traffic, and a geopolitical landscape that demands careful planning, and you understand why the Red Sea passage is treated as a rite of passage among circumnavigators.
When to Go — and When Not To
The single most important decision is timing. The summer months from June through August bring the strongest northerlies, with the Suez corridor funnelling wind to 35 knots or more — conditions that punish passage-makers relentlessly. The transition seasons offer brief windows. November and December see southerly to southwesterly winds in the southern basin, typically from Eritrea northward to roughly 19°N latitude, but these conditions rarely reach all the way to Egypt. Most experienced skippers aim to enter the Red Sea between October and January, cross as quickly as possible using every fair forecast, and accept that some motoring is inevitable.
Routing Strategy: East Coast vs. West Coast
Veteran skippers debate whether to favour the Egyptian/Sudanese coast or the Saudi/Yemeni shore. The western Egyptian and Sudanese coast offers the anchorages of Sharm el-Sheikh, Hurghada, and the offshore reef systems around the Fury Shoals, Zabargad Island, and Wadi Gimal. The Saudi Red Sea coast is largely inaccessible to foreign yacht traffic due to visa restrictions. Most ARC rally fleets and independent circumnavigators therefore work the western side, threading through the shallow channels of the Dahlak Archipelago near Eritrea before committing to the long haul northward.
The standard approach involves short daysails and motor-sailing, jumping from anchorage to anchorage, covering 50 to 80 nautical miles in a window of favourable pressure gradient before tucking behind a coral head or sandbar to wait out the next northerly blast.
Key Anchorages on the Western Corridor
Djibouti serves as the main staging port where vessels clear into the Red Sea. The marina at Doraleh, operated within the Port of Djibouti complex, provides a secure starting point with good provisioning. From here, the passage opens northward through the Bab-el-Mandeb Strait, where shipping density is extreme and radar watches must be maintained around the clock.
In Eritrean waters, the Dahlak Archipelago around 15°N offers a scatter of protected anchorages in the lee of flat coral islands. The anchorages near Dissei Island and around Dur Gaam have served generations of passage-makers. Eritrea requires advance clearance, and the bureaucratic process is worth completing: officials are generally cooperative with sailing vessels.
Sudan's offshore reefs — Suakin, Shaab Rumi (made famous by Jacques Cousteau), and the southern Egyptian reef complexes — provide world-class diving but demand cautious navigation with accurate charts and a sharp eye on the echo sounder. The reef at Sha'ab Rumi sits in open water with no warning, just 18 metres beneath the surface before it walls up to the surface.
Security Considerations
The Gulf of Aden and the approaches to Bab-el-Mandeb have been subject to piracy and military activity in connection with the ongoing conflict in Yemen. The International Maritime Organization and the Maritime Security Centre Horn of Africa (MSCHOA) both publish regular guidance. As of recent years, most sailing rallies — including the Red Sea Rally and Blue Water Rally — have moved their transit through these waters at speed, often in convoys, and with contact maintained via fleet radio nets on 8-megahertz single-sideband. Individual yachts are strongly advised to register with MSCHOA before transiting and to keep a regular schedule call with other vessels or an onshore contact.
North of approximately 22°N, in Egyptian waters, the security situation normalises considerably. The Egyptian coast guard is active, and yachts checking in at Port Ghalib or the Port of Safaga find officials accustomed to visiting vessels.
The Final Push to Suez
Above 24°N the Red Sea narrows further and the prevailing wind eases somewhat, though thermal effects over the Sinai Peninsula can produce strong katabatic blasts around Ras Mohammed and into the Gulf of Aqaba. The anchorage at Sharm el-Sheikh offers the last comfortable staging point before the northern approaches. Suez itself is a working port of industrial scale; the yacht anchorage at the Suez Canal Yacht Club in Ismailia, some 85 nautical miles north of the Red Sea entrance, represents the end of the passage. Canal transit requires advance booking, canal agents, and a transit fee — the paperwork is manageable and well-documented by the cruising community.
Preparing Your Boat and Crew
A Red Sea northbound passage demands mechanical reliability above all else. The ability to motor-sail at 5 to 6 knots in flat conditions, with enough fuel for at least 300 nautical miles under power, is the practical minimum. Watermaker function is essential; fresh water is scarce outside Djibouti and the Egyptian marina infrastructure. A reliable SSB radio, satellite phone or Iridium Go, and AIS transponder are no longer optional — they are baseline safety equipment for this corridor.
Crew briefings should cover watch rotation for shipping traffic. The Red Sea carries enormous freight volumes, and very large crude carriers give little margin. Night watches must be alert and the radar alarm set appropriately.

Zoom into the reef systems south of Hurghada, identify the Dahlak Archipelago anchorages, and plan your waypoints before you leave.
