Key Points
Waves are primarily generated by wind at the sea surface, not by tides or currents.
The key factors for wave growth are the strength, length, and duration of the wind fetch.
Storm systems with a combination of low and high pressure systems generate the strongest wind fetches for wave growth.
The orientation and movement of the storm system relative to the coast affects the swell direction and size.
Secondary swells and wind swells can interact with the primary swell, affecting wave quality.
Local bathymetry and geography influence how swells refract and focus at specific surf breaks.
Swells follow great circle paths due to the Earth's curvature, allowing remote swells to reach distant coastlines.
Atmospheric pressure changes can affect sea levels, impacting surf conditions at reef breaks and slabs.
Observing and understanding local swell patterns is crucial for predicting surf conditions accurately.
