About wave data
The wave climate at any location can be, and usually is, a combination of sea and swell and is often referred to as the total wave.
The graphs below provide information on sea waves and swell waves. They are updated as near to real-time as possible.
The near real-time wave data is downloaded from recording sites and graphics created for the web using software developed by Tremarfon Pty Ltd.
