🌍
The Caribbean is one of the hardest regions to read off a map, because what looks like a single scatter of islands is in fact three distinct chains, thirteen sovereign countries and more than a dozen territories still governed from Europe or North America. Getting the shape of it clear makes everything else — flights, ferries, visas, hurricane risk — easier to reason about.
A sea first, a region second
The Caribbean Sea sits between the Americas, bounded by Central America to the west, South America to the south and the island arc to the north and east. That arc is what most people mean by “the Caribbean”, but the definition stretches: the Bahamas and Turks and Caicos sit in the Atlantic rather than the Caribbean Sea and are almost always included anyway, while Bermuda sits far to the north and is almost never included.
The Greater Antilles: four big islands
Cuba, Hispaniola, Jamaica and Puerto Rico carry most of the region’s land area and most of its population. Hispaniola is the one that trips people up on a map: a single island shared by two countries, Haiti in the west and the Dominican Republic in the east, with a land border that behaves like a land border anywhere else.
The Lesser Antilles: the arc down to South America
From the Virgin Islands the chain curves south and east through the Leeward Islands, then the Windward Islands, then the ABC islands off the Venezuelan coast. This arc is volcanic in origin, which is why the islands are steep and green rather than flat and dry, and why several of them have an active volcano on them.
Who governs what
This is the part maps rarely make legible. Alongside the independent states sit:
- French overseas departments, which are part of France and therefore part of the European Union.
- Dutch constituent countries and special municipalities, with different statuses on different islands.
- British Overseas Territories.
- United States territories, where American federal law applies.
The practical consequence is that two islands twenty kilometres apart can have different currencies, different visa rules and different phone charges. Border logic here has to be checked island by island, in the same way it does across the boundaries drawn on the map of Central America.
Windward, leeward and why the words are backwards
The terms come from sailing under the prevailing trade winds, which blow from the east. Windward islands take the wind first, leeward islands sit in their shelter. The confusion is that the French and Dutch used the same words from a different vantage point, so an island called “leeward” in one language may be “windward” in another. On a map, read the position rather than the name.
The hurricane season, drawn on the same map
The Atlantic hurricane season runs from June to November, with the peak between August and October. Storms generally track from east to west across the Lesser Antilles before curving north, which means the eastern islands get the earliest warning and the least time to prepare, while the ABC islands off Venezuela sit largely below the usual track and are marketed on exactly that basis.
Getting between islands
Distances look short and journeys are not. There is no continuous ferry network across the region: ferries run within clusters, such as between Guadeloupe, Dominica and Martinique, or across the short hops in the Virgin Islands, but crossing from one end of the arc to the other means flying, often with a connection through a hub like San Juan, Panama City or Miami. A map that shows only distance will mislead you about time.
Where the Caribbean touches the mainland
Six Central American countries and three South American ones have Caribbean coastlines, and their coastal culture often has more in common with the islands than with their own capitals. Belize, the Caribbean coast of Nicaragua and the Guianas all read as part of the Caribbean world even though no map draws them into the island arc.
What the map does not show
Language, in this region, does not follow geography. Spanish, English, French, Dutch and a range of creoles sit side by side across islands that are visible from one another. Any plan built on the assumption that neighbouring islands work the same way — same language, same currency, same entry rules — will come apart at the first ferry terminal. For the wider frame this arc belongs to, the map of North America sets the continental context.
