Abstract Wave data are presented for Timaru, New Zealand, based on instrumental records collected between October 1981 and October 1982. Significant wave height ranged from 0.32-3.33 m with a mean value of 0.97 m. Significant wave period ranged from 5-17 s with a mean value of 10 s. The maximum wave height recorded was 6.30 m. A marked variation was found between summer and winter conditions. Winter months displayed a much greater range of wave conditions, significant heights were generally higher and significant periods longer.
