Wave Buoy

Site Info:
Fault Notice Update June 2015

Wave sensor components have been repaired with replacement parts from overseas. The repaired sensors are scheduled to be installed in the wave buoy by end of June, with re-deployment to site off Motiti Is at the soonest opportunity.

Fault Notice Update 24 March 2015

We are experiencing intermittent errors with the component of the wave buoy which measures wave height, wave period, and wave direction. The wave buoy has been brought back to shore to allow service agents to locate and repair the fault. Due to the specialist nature of the buoy, parts may need to be brought in from overseas which could mean the buoy is out of the water for an extended period of a month or more.  

Your patience while the issue is corrected is appreciated, and we apologise for any inconvenience this may cause.

The wave buoy is located 13 km off Pukehina Beach in a central position within the curve of the Bay of Plenty.

Significant wave height is an average measurement of the largest third of waves. Significant wave height corresponds well to visual estimates of wave height.

Maximum wave height is the largest wave recorded (peak to trough).

Significant wave period is the average time it takes for a wave to pass the wave buoy.

Wave direction is the direction from which the wave arrives at the buoy. This is shown as degrees from North in a clockwise direction. For example, a wave arriving from the east will have a wave direction of 90 degrees.

Sea surface temperature is measured from a sensor mounted near the base of the wave buoy (approximately 0.5 m below the sea surface).

The Swell Map model describes the sea state in the Bay of Plenty in near real time. The model should be used as a complementary source of information to augment traditional meteorological data and forecasts.
