Sea level in metres below today’s. A simple bathtub model: it lowers the sea everywhere by the same amount and does not simulate how the water would really drain.

How to read the map. Darker blue is deeper water. Tap anywhere to see how deep the sea is there, or how high the land is, and the nearest named undersea feature. Depths come from the GEBCO_2026 grid, which in most of the deep ocean is predicted from satellite measurements of the sea surface rather than surveyed by ship, and the map’s tiles are coarser than the grid, so narrow trenches read shallower on the map than their true depth. Not for navigation.

Yucatan Channel at a glance

  • 1 maverage depth
  • 1 mmedian depth
  • 21 mmaximum depth
  • 19 km²water area

Yucatan Channel is a channel. It is very shallow: nowhere in it is deeper than a few tens of metres in the grid. Inside its outline the GEBCO grid has about 19 km² of water, with an average depth of about 1 m (the middle value is 1 m) and a maximum of 21 m, found at 21.53° N, 86.97° W.

How deep is each part of the Yucatan Channel?

The bar splits the Yucatan Channel's water by depth. Each colour is a depth band, and the shares add up to 100%.

  • 0 to 200 m: 100%
  • 200 to 1,000 m: 0%
  • 1,000 to 4,000 m: 0%
  • 4,000 to 6,000 m: 0%
  • below 6,000 m: 0%

Named features near the deepest point: Cayman Trough (534 km), Sigsbee Deep (540 km), Mississippi Canyon (824 km), Walton fault zone (848 km).

Frequently asked questions

How deep is the Yucatan Channel?

On average about 1 m in the GEBCO grid (the middle value is 1 m). The deepest cell inside its outline is 21 m, at 21.53° N, 86.97° W.

How big is the Yucatan Channel?

About 19 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.

How much of the Yucatan Channel would be land if sea level dropped?

With the sea 10 m lower, about 19 km² (100%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.

Data: depths from the GEBCO_2026 grid, statistics worked out inside the Natural Earth outline of the channel. See data sources and licences. The GEBCO Grid should NOT be used for navigation or for any other purpose involving safety at sea.
