Look at a globe. Spin it. Most people look for the giant blue expanses of the Atlantic or the Pacific, but there is this skinny, jagged sliver of blue wedged tightly between the massive African continent and the Arabian Peninsula. That is it. If you are hunting for the location of Red Sea on world map, you are basically looking for the world’s most famous geological "crack."
It is a seawater inlet of the Indian Ocean. It’s long. It’s narrow. It looks like a finger pointing straight at the Mediterranean, though it doesn't quite touch it without human help. Geographically, it sits between $12^\circ$ and $30^\circ$ N latitude. Honestly, it’s one of the most volatile and fascinating spots on the planet, both geologically and politically.
Where Exactly Is the Red Sea?
To pin down the location of Red Sea on world map, you have to look at the northeast corner of Africa and the southwest tip of Asia. It’s the dividing line. On the western bank, you’ve got Egypt, Sudan, Eritrea, and Djibouti. On the eastern side, you’re looking at Saudi Arabia and Yemen. It’s about 1,400 miles long. That’s roughly the distance from New York City to Miami, but much narrower. At its widest point, it’s only about 220 miles across.
It’s saltier than most oceans. Why? Because no major rivers flow into it. Think about that. Most seas get a constant "wash" of fresh water from massive rivers like the Nile or the Amazon. Not the Red Sea. It just sits there under a brutal sun, evaporating like crazy, leaving the salt behind.
The Northern Split: Sinai and the Gulfs
At the very top, the sea doesn't just end in a blunt tip. It splits. This is the part people usually recognize from satellite photos. It forks into two "horns" that wrap around the Sinai Peninsula. To the west is the Gulf of Suez. That’s the one that leads to the Suez Canal, the man-made shortcut that keeps global trade from collapsing. To the east is the Gulf of Aqaba.
If you’re standing in Eilat, Israel, or Aqaba, Jordan, you’re at the very northern tip of this eastern branch. You can literally see four countries at once from some vantage points: Israel, Jordan, Egypt, and Saudi Arabia. It’s a tight squeeze.
The Southern Gate: Bab el-Mandeb
At the bottom, things get even tighter. The sea exits into the Gulf of Aden and then the Indian Ocean through a narrow strait called the Bab el-Mandeb. In Arabic, that translates to the "Gate of Tears."

It’s only about 18 miles wide at its narrowest point. This bottleneck is one of the most important maritime chokepoints in the world. If you block this, you block a huge chunk of the world's oil and consumer goods. This southern end is also where the Red Sea meets the Great Rift Valley system. It’s actually a baby ocean. Millions of years from now, it will probably be as wide as the Atlantic as Africa and Arabia continue to pull apart.
Why Does It Look Red?
It isn't actually red. Usually, it’s a startling, crystalline turquoise or deep navy. The name likely comes from Trichodesmium erythraeum. That’s a type of cyanobacteria—basically a sea-sawdust algae bloom. When these little guys die off, they turn the water a reddish-brown hue.
Some historians argue it’s actually about the compass. In some ancient languages, colors were used to denote cardinal directions. "Red" might have simply meant "South," just as the "Black Sea" might have referred to the "North." Whatever the origin, the name stuck.
Navigation and the Suez Shortcut
You can't talk about the location of Red Sea on world map without mentioning the Suez Canal. Before 1869, if you wanted to get a ship from London to Mumbai, you had to sail all the way around the entire continent of Africa. That’s a long trip. Thousands of extra miles.
The Suez Canal changed everything by connecting the Mediterranean Sea to the Red Sea. Now, the Red Sea is a global highway. On any given day, hundreds of massive container ships are threading the needle through this narrow corridor. It’s a high-stakes game of Tetris. When the Ever Given got stuck in 2021, the world realized just how much we rely on this specific geographic "crack."
The Ecosystem Nobody Expected
Most people think of the Red Sea as just a desert-edged shipping lane. They’re wrong. It’s home to some of the most resilient coral reefs on Earth. While the Great Barrier Reef is struggling with rising temperatures, the corals in the northern Red Sea seem weirdly fine. Scientists like Professor Maoz Fine from Bar-Ilan University have studied this "thermally tolerant" coral.

They believe these corals evolved to survive high heat as they migrated through the warm southern gates thousands of years ago. Basically, they’ve already been through a "pre-screening" for global warming.
- Diving Hotspots: Ras Mohammed in Egypt is widely considered one of the top five dive sites globally.
- Unique Species: About 10% to 15% of the fish species here aren't found anywhere else.
- The Blue Hole: Located in Dahab, it's a submarine sinkhole that is as beautiful as it is dangerous for divers.
Geopolitical Friction
The Red Sea is a neighborhood with a lot of "history." Because it sits at the intersection of Africa, the Middle East, and the Mediterranean world, it has always been a prize. Control over the Red Sea means control over trade.
In recent years, we've seen a massive "scramble" for bases. Turkey, the UAE, Saudi Arabia, and even China have set up ports or military outposts along the coast, particularly in Djibouti. Djibouti is a tiny country, but because of its location right at the Bab el-Mandeb strait, it hosts more foreign military bases than almost anywhere else on Earth.
Getting There: A Traveler's Perspective
If you’re looking to visit, you aren't just looking at a map; you’re looking at a diverse range of cultures. Egypt's Sinai Peninsula is the most accessible for western tourists. Places like Sharm El Sheikh and Hurghada are built entirely around the sea.
Further south, the tourism is raw. Sudan has incredible, untouched reefs and even the wreck of the Umbria, a legendary sunken ship. However, political instability makes it a tough "go." Saudi Arabia is also heavily investing in its "Red Sea Project," aiming to turn its pristine, untouched western coastline into a luxury tourism hub that rivals the Maldives.
How to Find It on Any Map
If you are staring at a map and can't find it, follow these three steps:

- Find the "V" shape of the Mediterranean.
- Look just to the right (East) for the "land bridge" between Egypt and Israel.
- Look directly south of that bridge for the long, thin blue line that separates the yellow desert of Africa from the yellow desert of the Arabian Peninsula.
That’s your target. It’s the water that looks like a scar on the earth.
What Most People Get Wrong
A common misconception is that the Red Sea is a stagnant "lake-like" body of water. It’s actually incredibly deep—over 7,000 feet in the central trenches. It's also part of an active tectonic plate movement. The Arabian Plate is moving away from the African Plate at a rate of about one to two centimeters per year.
It's literally a sea in the making. It’s not just sitting there; it’s growing.
Actionable Insights for Locating and Understanding the Red Sea
If you are using the location of Red Sea on world map for a project, travel planning, or school, keep these specific details in mind:
- Coordinate Check: Always look for the intersection of the Tropic of Cancer ($23.5^\circ$ N) which passes right through the middle of the sea.
- Map Search Tip: Use "Suez Canal" as your northern anchor and "Gulf of Aden" as your southern anchor to define the sea's limits.
- Climate Context: Remember that this area is almost entirely surrounded by desert. This creates high salinity and extreme water clarity, which is why it’s a magnet for underwater photography.
- Trade Significance: Understand that nearly 12% of global trade passes through this specific coordinate. Any disruption here usually results in a spike in oil prices or shipping delays worldwide.
