Abstract: Based on the observational data obtained during May 2007 - April 2008 , the features of wind and wave in the offshore area of Cu Lao Cau Bay were analyzed . We draw the conclusions as follows. 1) The monsoon is very prominent in the offshore area. The direction of the wind is almost northeasterly (southwesterly) in winter ?? ( summer), and the northeasterly monsoon is stronger than the southwesterly. 2) The directions of wave and wind are roughly consistent with the directions of normal wave and strong wave, which is eastward in winter and SSW-ward in summer. 3) The wind waves are normal, the wave spectrum has a multi-peak structure, and most of the main peaks are single-peak and two-peak structures. In the period of northeasterly (southwesterly) monsoon, the wave direction of peak value is south-southwest (eastward). Typhoon affects obviously the spectrum in the offshore area . This paper may provide a scientific basis for understanding the wind and wave characteristics in the Nansha Islands sea area. .

Key words: Cu Lao Cau Bay, monsoon, wave spectrum
