Tujuan dari penelitian ini untuk mengetahui model distribusi kecepatan angin dan pemanfaatannya untuk peramalan gelombang di perairan Laut Paciran, Jawa Timur. Data angin diperoleh dari stasiun pengukuran angin Badan Meteorologi, Klimatologi dan Geofisika (BMKG) Klas I Juanda Surabaya tahun 2007-2009, berupa data angin tiap jam. Pengolahan data angin dikelompokkan berdasarkan skala Beufort. Pengukuran tinggi dan periode gelombang menggunakan Sontek Argonaut XR. Peramalan gelombang menggunakan data angin dilakukan dengan menggunakan metode SMB dan Darbyshire. Hasil pengukuran data gelombang diperoleh hasil tinggi gelombang antara 3,2-82,9 cm dan periode gelombang 6,0 -7,9 detik, dari klasifikasi gelombang termasuk gelombang perairan transisi. Model distribusi data kecepatan angin menunjukkan bahwa untuk kecepatan angin kuat (1727 knot) pada musim barat durasinya antara 3-6 jam, sedangkan pada musim timur antara 1-4 jam. Dengan menggunakan metode SMB dan Darbyshire pada saat terjadi kecepatan maksimum pada musim Timur, tinggi gelombang mencapai 1,51 meter dengan periode 5,2 detik, sedangkan pada musim barat tinggi maksimum gelombang mencapai 2,4 meter dengan durasi 7 detik. Dari nilai MRE (mean relative error) data lapangan terhadap hasil peramalan dari data angin selama 3 tahun didapatkan nilai kesalahan relatif sebesar 0,3 34,32 % untuk tinggi gelombang dan 13,24 - 22,06 % untuk periode gelombang. Kata kunci: Distribusi kecepatan angin, gelombang, perairan laut Paciran, Jawa Timur The survey was conducted at Paciran East Java sea waters during October 2009. The purpose of this study to determine the wind speed distribution model and its use for forecasting waves in the sea waters Paciran, East Java. Wind data obtained from wind measurement stations Meteorology, Climatology and Geophysics (BMKG) Class I Juanda Surabaya in 2007-2009, in the hourly wind data. Wind data grouped by Beufort scale for processing. Height and wave period measured using Sontek Argonaut XR. Wave forecasting using wind data were calculated using SMB and Darbyshire method. The observation data obtained by the wave of wave height between 3.2 to 82.9 cm and wave period from 6.0 to 7.9 seconds, from the classification of waves including transitional waters. Wind speed data distribution model showed that for strong winds (17-27 knots) in the west season duration is between 3-6 hours, while in the east monsoon between 1-4 hours. By using the SMB method and Darbyshire in the event of a maximum speed of the Eastern season, wave height 1.51 m and periods of 5.2 seconds, while the west monsoon maximum wave height 2.4 meters and 7 seconds duration. The MRE (mean relative error) field data on the forecasting from wind data obtained during 3 years the mean relative error between 0.3 - 34.32 % of wave height and between 13.24 - 22.06 % of wave period.
