The exact depth of the Red Sea “where Moses crossed” is not known with certainty, because the Bible does not specify an exact location and modern scholars disagree on where the crossing took place. However, several popular proposed sites let us estimate how deep the water might have been.

Key idea in one line

Most popular Red Sea–crossing theories place the depth somewhere between a few dozen meters and around 700–900 meters (roughly 150–2,900 feet), depending on the proposed route.

Main proposed locations

1. Gulf of Aqaba – Nuweiba area

Many modern evangelical and popular-archaeology proposals place the crossing at or near Nuweiba on the eastern Sinai coast of the Gulf of Aqaba. In these models:

  • The seabed forms a kind of underwater “saddle” or land bridge, sloping down then back up.
  • Reported modern depths there range roughly:
    • Shallow margins of about 50 meters (≈165 ft).
* A deep central trench reaching around 700–900 meters (≈2,300–2,900 ft), often summarized as “about 2,500 ft deep.”

One faith-based geography site describes a maximum depth at a proposed Nuweiba crossing of about 2,500 ft (≈762 m), and notes that the first couple of kilometers from shore drop to roughly 250 m (≈800 ft) before rising again.

2. Straits of Tiran (southern tip of Sinai)

Another popular conservative-Christian model places the crossing at the Straits of Tiran, where the Gulf of Aqaba opens into the Red Sea proper.

  • There is an underwater ridge sometimes called a “natural land bridge,” with:
    • Depths around 200–300 m (≈650–980 ft) along the deeper parts of the channel.
* Some shallower sections as little as around 15 m (≈50 ft), though nearby canyons reach several hundred meters deep.

These proposals argue that a gently sloping path across this ridge could fit the narrative of a large group crossing in a single night.

3. Northern “Reed Sea” / marsh theories

Many academic biblical scholars question whether the Israelites crossed the open Red Sea at all, suggesting instead a northern body of water or marsh (often connected with “Sea of Reeds”).

  • In these models:
    • The water would likely be shallow—meters or even less in depth—more like lakes, lagoons, or marshy inlets than an open deep sea.
* The story is sometimes explained via rare wind and tide phenomena affecting shallow water rather than a deep-ocean crossing.

These views usually treat the narrative more as theological literature than a precise geographic report.

4. Open Red Sea (deep-water) academic modeling

Some scientific discussions model what it would take to part a deep section of the Red Sea or Gulf using wind and other natural forces.

  • One analysis notes that the Red Sea’s deepest trough ranges from about 1,200 to 2,600 m (≈4,000–8,500 ft) below the surface, far deeper than typical popular crossing models suggest.
  • This is more a physical thought experiment than a claim about the actual Exodus route.

So, how deep “where Moses crossed”?

Because:

  • The biblical text does not identify a precise, map-ready location.
  • Modern proposals differ (Nuweiba, Tiran, northern marshes, etc.).
  • Some scholars treat the event symbolically rather than geographically.

There is no single agreed-upon depth. However, if the question means “how deep is the sea at the popular ‘Nuweiba-style’ deep-water crossing site?” then:

  • Maximum depth along that proposed underwater path is often given as roughly 700–900 m (about 2,300–2,900 ft , frequently summarized as “around 2,500 ft”).

If instead one follows northern “Reed Sea” theories, the depth might only have been on the order of a few meters or less , more like a lagoon or marsh than an ocean trench.
