Waterways Bordering Central America: Two Oceans, Many Gulfs

Central America is an isthmus bordered by two oceans and numerous gulfs and bays:

Caribbean Sea (Atlantic) — North & East

• Gulf of Honduras — Belize, Guatemala, Honduras.
• Caribbean coasts of Honduras, Nicaragua (Mosquito Coast).
• Mosquito Gulf — Nicaragua/Honduras border.
• Gulf of Darién — Panama/Colombia border.

Pacific Ocean — South & West

• Pacific coasts of Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica, Panama.
• Gulf of Fonseca — El Salvador, Honduras, Nicaragua (shared).
• Gulf of Nicoya — Costa Rica.
• Gulf of Panama — Panama (Panama Canal entrance).
• Bay of Panama — larger embayment containing Gulf.

Strategic Significance

• Panama Canal (Gulf of Panama → Caribbean via Gatun Lake) — 6% of world maritime trade.
• Shortest sea route between Atlantic and Pacific.
• Nicaragua Canal proposals (historic/contemporary) would use San Juan River / Lake Nicaragua.

These waterways define Central America's climate (tropical, hurricane-exposed), economies (ports, canals, tourism), and geopolitics.
