Explanation / Answer

I'm assuming the water wave is a sine wave here. Since at time 0,

it's at a maximum, the wave height is a cosine function of the form

h = Acos(t) + B where A is the amplitude of the wave and B is the equilibrium height, taken to be 0. A = 1.3 and = 2f where f is the frequency of the wave, f = v/ = 12/95 = 0.1263 Hz (or waves per second).
= 0.7931 radians (4 d.p.) or 0.7931*(180/) = 45.46°.
h = 1.3*cos(0.7931*9) = 1.299 m
