December sits at the quiet end of the Red Sea calendar, when the water cools but visibility sharpens and the reef flats empty out. This egypt snorkeling in december guide explains what the sea actually feels like, when the gates are open, and how the wind shapes a day on the water. Expect concrete figures, not seasonal platitudes.
Quick answer
Yes — the Red Sea stays snorkelable all December, and Ras Mohammed National Park runs 08:00–16:00 every day of the week, with a 15 USD conservation fee per person paid in cash at the gate. Arrive between 08:00 and 10:00: early entry beats both the afternoon winds and the peak visitor crowds. The one caveat is thermal comfort, not conditions.
The Red Sea is a near-landlocked basin with almost no freshwater inflow, which makes it one of the saltiest and warmest open seas on Earth — and the reason egypt snorkeling in december remains viable long after reef seasons close elsewhere. Water that would be bracing in the Mediterranean stays swimmable here through midwinter. What changes in December is not whether the reef is accessible, but how long a person can comfortably stay in it. That distinction shapes most of the planning. Winter snorkelling in the Red Sea trades a few degrees of warmth for a sharper payoff: lower plankton loads, longer sightlines across the drop-offs, and far fewer swimmers finning over the shallow coral gardens of South Sinai. The reef platforms at Ras Mohammed National Park sit where the Gulf of Suez meets the Gulf of Aqaba, and the convergence drives a steady exchange of water across the fringing reef. Visibility in that corridor is a December asset. Thermal endurance is the December constraint, and the two work against each other — a reader who plans for one and ignores the other usually cuts the day short. Wind is the second variable, and it is more predictable than most visitors expect. The prevailing northerlies build through the afternoon, roughening the surface, raising chop over exposed reef edges, and reducing what the mask can actually resolve. Mornings are calmer by a wide margin. This is why the recommended arrival window is 08:00–10:00: it stacks the flattest water, the clearest light angle on the coral, and the thinnest crowds into the same few hours. A Red Sea snorkeling tour that launches late in the day is working against the weather rather than with it. The practical conclusion is simple. Treat December as a morning season. Build the day around an early gate entry, accept that afternoon conditions will be the weaker half, and plan water time in shorter, warmer blocks rather than one long immersion. Note too that the South Sinai parks hold the same daily schedule all week, so there is no single bad weekday to engineer around — only bad hours. Travellers researching egypt snorkeling in december often arrive expecting a compromise month and leave describing it as the most legible one on the calendar: predictable wind, predictable light, predictable water. The dedicated sections on this page break down the hours, the fee, access routes, reef highlights and the kit worth carrying.
“December is a morning season on the Red Sea: the flattest water, the clearest light and the thinnest crowds all arrive before ten.”
December offers mild air temperatures suitable for long days outdoors, though water temperatures begin to decline. Visiting during this month requires attention to wind patterns which can impact water clarity and site accessibility.
Air 23°C, Water 24°C
Stable conditions prevail before the peak winter wind season begins.
Air 21°C, Water 23°C
Stronger northerly winds may limit access to specific exposed snorkeling sites.

Early arrival between 08:00–10:00 ensures calmer surface conditions and better visibility.
Verdict: Weekday mornings throughout early December offer the most favorable balance of mild air temperatures and manageable wind conditions.
Ras Mohammed National Park offers diverse coral formations and high concentrations of marine life that remain active during December. These sites provide sheltered snorkeling conditions within the protected waters of the South Sinai region.
This site features a dramatic vertical drop-off covered in soft corals and dense populations of reef fish. Snorkelers often observe moray eels and large groupers within the reef crevices.
Enter from the boat deck during the morning slack tide.
Located on the cliffside, this area provides access to deep-water corals where pelagic species are frequently sighted. The currents here support vibrant fan corals and sponges.
Stay close to the reef wall to minimize current exposure.
Known for its underwater caves and sandy-bottomed channels, this site hosts large schools of jacks and trevally. The clear water provides high visibility for observing reef sharks and rays.
Swim through the shallow channels at low tide.
A large colony of sea anemones blankets the reef slope, hosting thousands of clownfish. This site serves as a nursery for various species protected by the deep-water currents.
Look for the anemones on the upper reef plateau.
December snorkeling at Ras Mohammed National Park needs warmer gear and tidier paperwork than a summer trip, so work through these in order.
