Extreme wave indices for New Zealand coastal and oceanic waters

This report updates indices for coastal and ocean extreme waves previously developed   to quantify the occurrence of extreme wave events in New Zealand on an annual basis. Indices previously derived for 2008–2014 have been extended to 2016 and 2017, based on numerical model outputs. 

This report updates indices for coastal and ocean extreme waves previously developed   to quantify the occurrence of extreme wave events in New Zealand on an annual basis. Indices previously derived for 2008–2014 have been extended to 2016 and 2017, based on numerical model outputs. 

Extreme wave events can damage marine ecosystems and affect coastal infrastructure, ocean-based industries and other human activities such as ferry crossings in the Cook Strait. Reporting on extreme waves provides us with greater insight into their frequency, particularly as sea level.
