Hawaiian Trade Winds

Trade Winds
Accounting for 70% of all winds in Hawaii, trade winds are the most common winds over Hawaiian waters. These persistent winds, which blow from a NE to ENE direction, became known as trade winds centuries ago when trade ships carrying cargo depended on the broad belt of easterly winds encircling the globe in the subtropics for fast passage. Winds blow from each of the other quadrants (SE, SW, and NW) 10% of the time.
