  The east coast of Malaysian waters is of importance because it harbors the country’s fisheries resources. Determination of its spatial and temporal variations enables understanding of the coastal waters dynamics and physical processes affecting the region. Aqua MODIS satellite data of normalized water-leaving radiance (nLw at 412, 443 and 551 nm) from January 2006 to December 2010 were processed to determine variability using the classification approach. Five spectrally defined classes were obtained to represent the coastal water characteristics based on false color images. Variability was influenced by the outflow of terrestrial water which carries the load of suspended materials into the ocean and it moved according to the northeast and southwest wind and current propagation. Empirical Orthogonal Function (EOF) analysis of nLw 551 imagery explained the variability in temporal and spatial scale. The first mode of the EOF analysis (77.38% of variance) indicated the seasonal cycle. The second mode (4.96% of variance) explained the inter-monsoon period indicating the variability between the two periods of the Northeast and Southwest monsoon in this area. The third mode (3.17% of variance) indicated the Northeast monsoon which showed high variability toward the coastal water region associated with strong wind. The fourth mode (1.91% of variance) explained the Southwest monsoon associated with weakened wind and showed spreading surface pattern further from the coastline. Understanding of this variability would greatly contribute to coastal fisheries management and planning that could provide benefits to the coastal area as well as the productivity of this region.
