Pacific North Equatorial Current

The northern tropical Pacific offered a westward sailing corridor in the early modern period. Northeast trade winds and the North Equatorial Current generally favoured movement toward the western ocean, although weather and the position of islands complicated voyages. Crews still faced long stretches of open water and depended on carefully rationed provisions.

From the sixteenth century, Spanish voyages across the Pacific connected the American coast with the Philippines. Manila became a meeting place for Chinese and other Asian merchants and Spanish American silver. Pacific islanders also maintained older navigational traditions, using knowledge of stars and wave patterns to travel between islands. Both ocean conditions and learned skills shaped these maritime connections.
