Fig. 13 shows the simulated sea surface heights in the upper part of the gulf at 08UTC on November 4, 1997. The time of
peak surge agrees well with the time of peak wave height. The sea level raised to a maximum at this time at about 70 cm in
the Cha-Am area, around latitude 12.8N in the western coast of the upper GoT, very close to north of Huahin.
