The wave heights produced by this model are based on significant wave height calculated over a 20-minute sample. The maximum wave height for that same period will be markedly higher than what is shown.

The accuracy of the simulated wave heights depends on the validity of the assumptions made about deep-water wave conditions and the local wind speed and direction. At any given location, the local wind speed and direction in particular may not be accurately represented. This may cause the modelled wave conditions to differ from actual conditions.

NIWA makes no representations or warranties regarding the accuracy of the modelled results, or the use to which these results are put. Accordingly NIWA accepts no liability for any loss or damage (whether direct or indirect) incurred by any person through the use of or reliance on the modelled results.
