As the biggest archipelago country in the world, a lot of places in Indonesia are very potential for maritime economy industries but also suffered from negative impact of the global sea level rise. It was identified as one most contributing factors which is threatening Indonesia coastal water by coastal flood, including the research area where is located in Sidoarjo Regency. To adapt the climate change, it needs to have knowledge and advanced technology along with comprehensive data. Unfortunately, among reseachers and civil construction designer found that the available raw datas are usually incomplete which causes major problem in taking measurements data during the years.

The aim of this research is to utilize synoptic data for coastal adaptation of climate changing design and construction. The data were collected from the National Oceanic and Atmospheric Administration (NOAA) for 16 years that will be processed into wind rose and fetch length in the research area. The outcomes in the form of sea wave height prediction are obtained from the analysis of graphical and analytical calculations with respect to Shore Protection Manual 1984. Regarding graphical and analytical calculation demonstrates that the maximum sea wave height are 0.14 - 0.17 meters and 0.13 - 0.22 meters, respectively. Thus, these data will serve as supporting data for the coastal protection design and construction against global sea level rise.

In this research, the synoptic data were taken from National Oceanic and Atmospheric Administration (NOAA) which contain the hours of the wind direction and velocity. The data are summarized based on wind direction and wind speed with respect to Beaufort scale. Figure 1 shows that the dominant wind direction of 16 years of data is the East along with the maximum speed is 35.466 km/h. Figure 1. Windrose of the Research Area (2000-2016)After the wind rose is obtained, calculated the length of fetch in with respect to the dominant wind direction from the wind rose. Regarding Figure 2, the maximum fetch length is 125 km.

Table 1 demonstrates the result of sea wave height prediction in the research location. Regarding graphical and analytical calculation demonstrates that the maximum sea wave height are 0.14 - 0.17 meters and 0.13 - 0.22 meters, respectively.
