In this study, long term variations of significant wave height are studied using ERA-Interim reanalysis data from ECMWF (European Centre for Medium-Range Weather Forecasts) for 35 years period from 1980-2014 in Indonesia Seas. The ERAInterim reanalysis data provides wave height data with resolution of 0,750 x 0,750. This paper studied monthly variation in significant wave height by creating monthly data and taking the mean of those months over 35 years period. A statistical analysis of wave time series data has been performed to test the significance of trend during 35 years period. The results show that the mean significant wave height in the south of Java Sea show statistically significant increasing trend for all month.
