Moderate to fresh southerly flow winds prevail S of the monsoon trough, with gentle winds north of the monsoon trough. Combined seas are currently 5 to 8 ft in a mix of wind waves and southerly swell. Winds will diminish to moderate S of the monsoon trough by early Fri with seas subsiding slightly. Long period southerly swell will impact the waters W of Ecuador by the end of this weekend into early next week with seas building to 6 to 8 ft. REMAINDER OF THE AREA...
