U.S. City Due West of Bermuda: None

No U.S. city lies due west of Bermuda. Bermuda (32°18′N, 64°47′W) sits in the open North Atlantic.

• Charleston, SC (32°47′N, 79°56′W) is the nearest major U.S. city—but it's ~850 nm northwest, not due west.
• Cape Hatteras, NC (35°15′N, 75°31′W) is closer (~560 nm) but north-northwest.
• Due west (same latitude) hits only ocean until the U.S. coast near the NC/SC border—but no city there.

Bermuda's isolation (600+ nm from nearest land) is why it was a strategic naval base.
