With average sea temperatures around 22°C (72°F), January brings refreshing yet comfortable conditions both above and below the surface.

Red sea water temperature january

The Red Sea water temperature in January averages 21°C to 23°C (70°F to 73°F), making it one of the warmest winter sea temperatures anywhere within a short flight from Europe. Despite being mid-winter, the water remains comfortably swimmable — especially in sheltered bays and resort areas.

Average Water Temperatures by Destination

• Sharm El Sheikh: 22°C–23°C

• Hurghada: 21°C–22°C

• Marsa Alam: 23°C–24°C

• Dahab: 21°C–22°C

• El Gouna: 21°C–22°C

The southern Red Sea (Marsa Alam, Hamata, Berenice) stays slightly warmer thanks to its proximity to the tropics. Northern spots like Dahab and Taba feel a bit cooler but still pleasant for winter swimmers.

How It Feels in the Water

• You’ll notice the water feels refreshing but not cold.

• Morning swims can feel cooler, while afternoons are noticeably warmer.

• Wetsuits are optional for swimming but recommended for long dives.

Why the Red Sea Stays Warm in Winter

The Red Sea is naturally warm year-round due to:

• Its high salinity and density, which retain heat longer

• Being bordered by desert climate zones with mild winter air temperatures

• Low rainfall, meaning minimal cooling from storms

In short, January is one of the best months for underwater visibility — calm seas, warm water, and minimal plankton.

What to Wear & Prepare For in the Water?

January is a fantastic month for Red Sea swimming, snorkeling, and diving — but the cooler winter conditions mean a bit of preparation goes a long way. Here’s exactly what you should bring and wear to stay comfortable, warm, and ready for long sessions in the water.

What to Wear in the Red Sea in January

1. Swimsuit or Rash Guard
A basic swimsuit is fine for short swims, but many travelers prefer a rash guard for extra warmth and sun protection. Rash guards are especially useful when snorkeling for long periods.

2. Wetsuit (For Snorkelers & Divers)

Some Red Sea beaches have coral shelves or rocky entry points.

• Water shoes help protect your feet.

• Snorkel fins make it easier to handle small winter currents and give you more control in open water.

4. Mask & Snorkel
While rental gear is widely available, bringing your own ensures better fit, cleaner equipment, and more enjoyable snorkeling sessions.

Even with warm water, the breeze can feel cool once you step out. A quick-dry towel or poncho helps you warm up fast.

What to Prepare For

1. Cooler Air Temperatures
Expect daytime temperatures of 21°C–25°C and cooler mornings. You’ll warm up quickly after a swim, but packing a light jacket or hoodie is smart.

2. Clear, Bright Sun
January still brings strong UV rays.
Pack:

• Reef-safe sunscreen

• Sunglasses

• A hat or cap

3. Excellent Visibility
Water clarity often reaches 20–30+ meters in winter. Bring an underwater camera if you want to capture reefs at their best.

4. Mild Surface Currents
Bays are calm, but some open-water sites can have light currents.
Follow your guide’s instructions, especially when snorkeling near reef edges.

5. Boat Trips
If you’re heading out on a snorkeling or diving boat:

• Bring a windbreaker for the breeze

• Pack snacks and water

• Use dry bags for valuables

6. Marine Life Encounters
Winter offers a good chance to see turtles, rays, and dolphins — especially in Marsa Alam. If you’re snorkeling, patience and calm floating help you spot more.
