Diving in Egypt in December

Conditions in December

December in Egypt’s Red Sea offers a unique and often underestimated diving experience. While much of the Northern Hemisphere shivers, you’ll find remarkably pleasant conditions here. The air temperature hovers comfortably between 20-25°C (68-77°F) during the day, making surface intervals enjoyable without the intense summer heat. Nights can be cooler, dropping to around 15°C (59°F), so a light jacket or fleece is a wise addition to your packing list, especially if you’re enjoying evenings on deck.

The sea state during December is generally calm, particularly within the sheltered reefs. However, exposed sites in the open Red Sea can experience choppier conditions, especially if there's a northerly wind. This is a common pattern for the region but usually doesn't disrupt diving significantly. Water temperatures are cooling down from their summer highs, settling into a range of 23-25°C (73-77°F). This is still wonderfully warm for diving and generally much more comfortable than many other global destinations at this time of year. Visibility remains consistently excellent, often exceeding 30 meters (100 feet), providing crystal-clear views of the vibrant coral gardens and abundant marine life.

Currents can be a factor at exposed offshore reefs, as is typical for the Red Sea’s world-class wall dives. These currents are usually moderate but can occasionally pick up, offering exhilarating drifts and bringing in nutrient-rich water that attracts larger pelagics. Experienced divers will relish these conditions, while those new to current diving will find suitable, more sheltered alternatives if preferred. Overall, December presents a fantastic window for divers seeking comfortable conditions without the peak season crowds.

What you will see

December diving in Egypt unveils a spectacular array of marine life. While the massive whale shark aggregations of summer might be past, you’re hitting the sweet spot for many other pelagic encounters. Oceanic whitetip sharks are a prominent feature, especially around the offshore pinnacles like Elphinstone and Daedalus. Their curious nature often brings them close, offering incredible photographic opportunities. Hammerheads, though more elusive than in the warmer months, are still seen, particularly at deeper depths around The Brothers islands. Reef sharks of various species – grey, whitetip, and silvertip – are perpetual residents and are frequently encountered patrolling the reef edges.

Beyond the apex predators, the Red Sea’s famous schooling fish are as prolific as ever. Dense schools of snappers, barracuda, and trevally can engulf you at sites like Jackson Reef in Tiran. You’ll also be delighted by the sheer biodiversity of reef fish; iridescent parrotfish, elegant angelfish, and a kaleidoscope of butterflyfish are constantly flitting around the corals. The vibrant soft corals, a hallmark of Red Sea diving, are in full bloom, providing stunning backdrops to the busy reef ecosystem.

For those with an eye for the smaller things, the macro life is also thriving. Nudibranchs, often overlooked in the grandeur of the bigger creatures, can be found in a surprising variety of shapes and colors. Stonefish, scorpionfish, and crocodilefish are masters of camouflage, presenting a fun challenge for keen-eyed divers. While December isn't a peak manta season across the board, sporadic sightings can occur, particularly in the southern Red Sea. Keep your eyes peeled for turtles gliding gracefully, and don't forget the resident pods of dolphins that often make impromptu appearances, especially around Sha’ab El Erg (Dolphin House).

Top dive sites this month

For an unforgettable December dive trip, focus your itinerary on the classic offshore pinnacles and the southern Red Sea. The Brothers Islands (Big Brother and Little Brother) are almost non-negotiable. Their exposed location and strong currents in December make them prime real estate for oceanic whitetips and silky sharks. You’ll also find incredible coral growth and the wrecks of the Aida II and Numidia to explore. The sense of adventure and the raw, untamed marine life here are unparalleled.

Further south, Daedalus Reef continues to be a magnet for large pelagics, particularly hammerhead sharks if you arrive early and descend deep. Its sheer walls are a continuous show of reef fish and schooling barracuda. And of course, Elphinstone Reef is a must-dive. Renowned for its stunning walls covered in soft corals and frequented by oceanic whitetip sharks, especially in the autumn/winter months, it consistently delivers thrilling encounters. For those venturing into the deep south, sites like St. Johns and Fury Shoals offer equally pristine reefs, vibrant coral gardens, and a greater chance of manta rays, though these sightings are slightly less predictable in December.

Practical tips for your trip

Given the water temperature of 23-25°C (73-77°F), a 5mm wetsuit is generally recommended for December diving in Egypt. If you tend to get cold easily, or plan on doing multiple dives a day, a 7mm suit or even a 5mm with a hooded vest might provide extra comfort, particularly towards the end of long dive days. For those who are consistently warm, a 3mm suit could suffice, but most divers prefer the added insulation of a 5mm. A good quality hood is also a great idea to retain body heat.

December diving in Egypt is suitable for a wide range of divers, from advanced to intermediate. While beginners can enjoy many shallower, sheltered sites, the more iconic offshore reefs known for pelagic encounters often involve deeper dives and currents, which are better suited for experienced divers. Many liveaboards cater to all levels, with dive guides providing briefings and support. Liveaboard availability in December is generally good; while it’s not peak season, the Christmas and New Year period can see higher demand, so booking in advance, especially for popular routes like The Brothers and Daedalus, is always a smart move. During other times in December, you might even find some excellent deals!

When packing, think layers for above deck. A light long-sleeved shirt for sun protection, a fleece or light jacket for evenings, and comfortable casual wear. Don't forget reef-safe sunscreen, a wide-brimmed hat, and polarized sunglasses. Bring any specialized dive equipment you prefer, though rentals are readily available. Consider packing a small medical kit with any personal medications and seasickness remedies. Embrace the quieter atmosphere; you’ll often find yourself with fewer divers on exceptional dive sites, making for an even more intimate and memorable experience. It’s a truly rewarding month to explore the Red Sea’s underwater wonders.
