100-year return storm surge height η100 and return wave height H100 at Ise Bay which have not been discussed together previously are compared. Both η100 and H100 are estimated by hindcastings for 107 storms in the past 56 years from 1950 to 2005 using the same computational grid and the same wind conditions. Spatial distribution shows storm surge height is large at coastal areas especially at the inner part of the bay and wave height is large at offshore areas. Alongshore distribution illustrates η100 along the coast is larger than that of H100 near Nagoya and Atsumi Bay. η100 near Nagoya is about 3.2m which is nearly 1.5 times H100. Spread parameter of storm surge η50/η10 is larger than that of wave height H50/H10 and η50/η10 is large at the coast near Nagoya and Atsumi Bay.
