Sea Distance: Miami to Los Angeles via Panama Canal

Miami → Los Angeles by Sea: The Panama Canal Route

The nautical distance from Miami, Florida, to Los Angeles, California, via the Panama Canal is approximately 4,600 nautical miles (8,500 km / 5,300 statute miles).

Route Breakdown

1. Miami → Panama Canal (Atlantic side): ~1,000 nmi (via Florida Straits, Caribbean).
2. Panama Canal transit: ~50 nmi (8–10 hours).
3. Panama Canal (Pacific side) → Los Angeles: ~3,550 nmi (along Central/Mexican coast, then north).

Time Estimates

• Container ship (20 kn): ~9–10 days + canal transit.
• Cruise ship (18–22 kn): 10–12 days including port calls.
• Fast ferry (30+ kn): ~6–7 days (rare).

Alternative: Cape Horn

Before the canal (1914), ships sailed ~13,000 nmi around South America — 3–4 weeks longer.

Key Points

• Canal saves ~8,000 nmi vs. Cape Horn.
• Panamax / Neopanamax locks limit beam/draft.
• Tolls: ~$150K–$450K per transit (by vessel size).

The canal remains the vital shortcut between the Atlantic and Pacific for US East–West coast shipping.
