From the beaufort scale, from 7 to 10 knots, one should start to see whitecaps...
What I think is that it depends on the distance that the wind is running on the water surface. Lets say, off-shore 10 knots: no whitecaps close to shore, but if you go 1 mile out, youre gonna see them; Now if you have an on-shore of 10 knots, itīll be coming from far of the coast, and there will be a lot of it...
Also, the state of the water will depend on how much time the wind has been blowing for; half an hour of 6 knots on shore, no whitecaps. 6 knots blowing for 2 hours, sure you will see it.
