Geography & Environment
The Bahamas is a low-lying Atlantic archipelago built largely on limestone and coral platforms. Mount Alvernia on Cat Island, at about 63 metres, is the national high point, while reefs, banks and shallow marine environments dominate the wider physical setting.

The Bahamas at a Glance
Low limestone islands, coral reefs and shallow banks define the physical profile of The Bahamas.
Physical geography
terrain · drainage · setting
Long, low limestone islands and coral formations dominate, with very limited relief. The relief anchor used here is Mount Alvernia; it is shown as a named physical reference rather than as a ranking claim.

Climate pattern
The Bahamas has a subtropical marine climate, with a drier season in winter and spring and most rainfall concentrated in the warmer part of the year.
Water and landform context
Low-lying islands are surrounded by coral reefs, extensive sand flats and shallow banks, so marine geography is more prominent than inland relief or river drainage.

What The Bahamas' geographic profile is telling you
The Bahamas is best understood as a marine archipelago rather than a high-relief landmass. Low limestone islands sit within a much larger system of shallow banks, reefs and Atlantic waters.

Sources & methodology
The Bahamas profile uses government environmental-review material that compiles national geographic composition and Department of Meteorology climate information, including Mount Alvernia and the country's low-lying island setting. Time-sensitive environmental percentages are not added without a separately dated source.
