As European divers have long known, the Red Sea is off-the-chart diving — one of the planet's richest marine ecosystems, a sea landlocked by desert on every side, formed millions of years ago when the Arabian Peninsula split from North Africa. The result is something extraordinary: a warm, sheltered body of water that has evolved into an almost impossibly diverse underwater world, welcoming to first-timers yet endlessly challenging for the most seasoned divers.
Conditions & Seasons
Thanks to its warm waters, rich marine life, and legendary dive sites, Egypt's Red Sea is a year-round diving destination. For optimal conditions, plan your trip during spring (March to May) or autumn (September to November), when visibility is superb and pelagics are abundant. Visibility is at its best, reaching 30 metres or more, and summer water temperatures reach a bath-like 28–30°C — a 3mm shorty or even a rash guard is often enough in the warmer months. In winter, water temperatures typically range from 21–23°C, so a 5mm wetsuit (or even a 7mm for some divers) is recommended. Reefs in open-sea areas exhibit moderate current fluctuations during dives, while those with shallow seabeds may experience more noticeable variations — and at the famous offshore reefs and walls, strong currents and deep drop-offs mean conditions demand respect and experience.
Marine Life
The Red Sea is a unique marine ecosystem characterised by high levels of endemism — approximately 10% of its fish species are found nowhere else on earth — with nutrient-rich waters supporting over 1,000 species of fish and 200 species of coral. Divers can encounter vibrant coral gardens teeming with butterflyfish, angelfish and parrotfish, while larger creatures such as reef sharks, hammerheads and manta rays often make appearances, eagle rays and the elusive dugong add special thrills, and turtles glide gracefully through the water. The offshore reefs serve as cleaning stations and hunting grounds for various shark species, including the elusive Thresher and the iconic Scalloped Hammerhead. Hammerhead sharks begin their appearances at the remote southern reefs — Brothers, Daedalus and Elphinstone — with June to September bringing the highest chance of hammerhead sightings. In the sandy shallows of the south, the rare and gentle Dugong can be found grazing on seagrass, while pods of Spinner Dolphins are frequently encountered in lagoons like Sataya.
Iconic Dive Sites
Depending on which region of Egypt you choose to visit, your diving holiday could include shallow patch reefs, drift dives and walls, or a collection of some of the most interesting wrecks you are likely to find anywhere. The undisputed star is the SS Thistlegorm: widely regarded as one of the best dive sites in the world, this World War II wreck is a submerged museum, frozen in time with its cargo of trucks, motorcycles and locomotives still intact. The wreck lies in 30m of water, with the deepest point — the prop — at about 32m, and the shallowest section at 16m. Further south, Shark and Jolanda reefs within Ras Mohammed National Park offer strong currents, spectacular soft coral and the wreck of the Cypriot cargo ship Jolanda. For those venturing offshore, the Brothers and Daedalus are best suited to experienced divers, with strong currents, deep drop-offs and open-ocean conditions including surge.
Getting There & Access
Land-based diving is excellent, particularly in Dahab (known for the Blue Hole and Canyon) and Marsa Alam, where house reefs and shore dives offer flexibility and comfort. For divers seeking to explore the full scope of Egypt's Red Sea, liveaboards offer a range of experiences, from wreck safaris in the north to deep-sea shark expeditions in the south. The main gateway hubs are Hurghada and Sharm el-Sheikh, both well served by international flights, with thriving dive centre communities and easy boat access to the region's top sites.
Recommended ISC Certifications
The Red Sea suits divers of all levels, but to make the most of its deeper walls, legendary wrecks and current-swept offshore reefs, the following ISC courses are recommended:
