The direction of incoming swell is often given in degrees and indicates what?

The direction of incoming swell is typically expressed in degrees relative to true north, which allows for a clear understanding of the swell's approach towards the coastline or the sailing area. This angular measurement indicates where the waves are coming from, giving sailors critical information for navigating safely and effectively.

When swell direction is provided in degrees, it helps in determining how the waves will interact with the shoreline and the prevailing wind conditions. Understanding both the direction and angle of incoming swells assists sailors in assessing potential impacts on their vessel and planning suitable maneuvers while at sea.

Using the terms "direction" and "angle" accurately captures the essential information conveyed by swell direction, reinforcing its importance for operational decision-making in sailing contexts.
