Wave height around New Zealand

Wave height around New Zealand

Oceanographers use the term ‘significant wave height’ as a measure of the larger waves in a sea. It is the average measurement of the highest one-third of waves. This map shows the average significant wave height around New Zealand over 20 years. The southern coast generally has the largest waves and the north-eastern coast the smallest.
