Swells approaching from a perpendicular angle to the shore typically result in more consistent and powerful wave breaks. Conversely, swells arriving at oblique angles may produce less defined wave shapes and currents, altering surfability and swim conditions. This angle greatly defines how waves refract and break, especially across reef environments.
- Influence on Break Characteristics
Swell direction is a primary determinant of where waves will break along the coast. A swell approaching from the south may generate more consistent breaks along a specific reef section, while a swell from the west could lead to wave dissipation. It is also a very important factor in predicting currents. It causes wave direction to be altered by specific topographic features. The angle determines if a wave will break on sand bar, reef, or other bottom structures.
- Relationship to Rideability
For surfers utilizing a coastal assessment, swell direction is a pivotal factor when evaluating rideability. Some breaks may only function optimally under specific swell directions, while others are rendered unrideable. The same swell height could generate varying levels of enjoyment depending on the angle of incidence.
- Safety Considerations
Swell direction also affects safety. It can create conditions that funnel currents into certain areas, creating unexpected rip currents. A shift in swell direction can quickly alter the location of these currents, increasing the risk to swimmers and surfers alike.

Examining wind speed data, within the context of a coastal assessment, allows for predictions about water surface conditions and associated hazards.
The impact of wind speed is determined by its direction relative to the coastline. Offshore winds (blowing from the land towards the sea) can create cleaner, more organized wave faces, as they hold up the wave, reducing the effects of gravity, thus resulting in desirable surfing conditions. Conversely, onshore winds (blowing from the sea towards the land) often generate choppy, disorganized waves, negatively impacting wave quality and increasing the difficulty of paddling. Strong onshore winds can also create dangerous currents, posing a risk to swimmers and surfers. For example, a coastal assessment indicating sustained onshore winds of 20 knots would suggest rough sea conditions unsuitable for novice surfers. Conversely, light offshore winds accompanying a moderate swell forecast would indicate potentially favorable surfing conditions, provided other factors are favorable.
In summary, wind speed, considered in relation to its direction, provides critical insight into the quality of water conditions at Ewa Beach. Its influence on wave formation, surface texture, and current generation underscores its importance in coastal monitoring. An accurate understanding of wind speed data, along with other parameters, is essential for safe and enjoyable ocean activities.
