I suspect this to be a mere case of Sensor Error translating to an INT16 maxing out at FF aka 255, which would perfectly fit to a waveheight of 25,5m if stored at 0,1m precision.

is this anything close to the supplied function:
for(float elevation, iteration, scale, waveHeight, positionModifier, globalOffset, horizontalDisplacement; iteration < 90.; offsetIncrement = .01 - .02 / exp(max(scale, elevation) * 3000.) / horizontalDisplacement) {
vec3 point = vec3((frameCoordinates.xy - .5 * resolution) / resolution.y * globalOffset 2., globalOffset);
point.zy *= rotate2D(.5);
elevation = point.y;
horizontalDisplacement = elevation point.x * .3; point.z = time; // Assuming 't' is a time variable
for(scale = .6; scale > .001; scale *= .7) {
point.xz *= rotate2D(5.);
positionModifier = (point.x point.z) / scale time time;
elevation -= waveHeight = exp(sin(positionModifier) - 3.) * scale;
horizontalDisplacement = abs(dot(sin(point.xz / scale * .3) * scale, resolution / resolution));
}
globalOffset = elevation = min(elevation, horizontalDisplacement * .5 - 1.); }

At6AM local time earlier today, Reunion Island was placed on purple alert, the highest level meaning imminent danger, as the #BelalCyclone runs through it
Just looking at #WaveHeight gives an idea of the gravity of this extreme event ๐
Our thoughts are with the people in Reunion

Oh #Buoy! Our research team recently installed a new real-time SoFar #DataBuoy at East Flower Garden Bank with the help of the @marinesanctuary and Xinping Hu from TAMU-CC .
This provides offshore #WaveHeight, #WindSpeed, and #WaterTemp.

Fake. Video is compressed sideways to exaggerate waveheight. The ship is NZ Navy HMNZ Otago and the original video is here. Still impressive and no need to fake it.
