  • More than 200 types of coral build vast reef systems along the Egyptian coast.
  • Year-round water temperatures range between 22°C and 30°C, offering perfect conditions for snorkeling and diving.
  • Visibility is often more than 30 meters, making it one of the clearest seas in the world.

From the lively resorts of Hurghada and Sharm El Sheikh to the untouched southern reefs of Marsa Alam, the Red Sea offers endless opportunities to explore an underwater paradise.

Winter in the Red Sea is about serenity. It’s the perfect time for travelers who want peaceful exploration and spectacular underwater photography.


Spring (March – May): Colorful Reefs and Active Wildlife

Spring is one of the best times to experience the full beauty of the Red Sea. As temperatures rise, coral reefs burst into color, and marine life becomes more active. Water temperatures reach 24–27°C, creating ideal conditions for long snorkeling or diving sessions.
