Key
Hs Height of significant wave (metres). This is the average height of the highest one third of the waves in the record.
Hmax Maximum height of the waves (metres) in the record.
Tz Average wave period. This is the average time (seconds) between all waves in the record. The more technical name for this quantity is the zero-crossing period.
Tp The peak wave period (seconds) is the period at which the peak of the wave spectrum occurs.
Spectral density Distribution of the variance of the surface elevation with wave period or frequency (proportional to the wave amplitude squared).

Notes

This page contains wave observations from a moored wave data buoy located 4.2nm West of Cape du Couedic Light House (Kangaroo Island) in 44 fathoms (80 metres). Location: 36.07S, 136.62E.

  • These observations have been taken from the Bureau of Meteorology's real-time system. These data are automatically generated and are not quality controlled. It is possible for incorrect values to appear. Further information can be found about Latest Weather Observations. Please check the disclaimer before using these data.
  • All times and dates are in South Australian local time.
  • Data for this page is downloaded manually approximately every 3 hours.
  • Each 'observation' (or record) is obtained by sampling the waves for 27 minutes.
  • This page is automatically updated every hour from available data.
