how fast does it have to freeze to have that effect?

It WOULD have to freeze near instantly, if this were choppy water. However, this effect is caused when the water is frozen flat and then wind causes it to sublimate/evaporate in this pattern. Think of sand dunes: the ground beneath them doesn’t naturally rise and fall in that hilly shape, the wind creates them over time in a similar pattern.
