Abstract: Measurements of waves in a small craft harbor were analyzed for the purpose of determining the existing wave climate energy levels causing the excessive agitation of moored small craft and degradation of the harbor infrastructure. Wave measurement instruments were installed at three locations within the harbor and one nearshore location. Frequency domain analysis of the measured pressure time series resulted in one-dimensional energy spectra spanning the range of gravity and infragravity waves. Joint distributions of significant wave height (Hmo) and spectral peak frequency, histograms, and cumulative distributions are presented and discussed.
