  6. 18. ** Scale goes up to 12 and is used throughout the world as an indicative of weather and to issue warnings on hurricanes and storms Beaufort Number Wind speed (mph) Description Wave Height (m) Sea Conditions 0 <1 Calm 0 Flat 1 1-3 Light air 0.1 Ripples without crests 2 3-7 Light breeze 0.2 Small wavelets. Crests not breaking 3 8-12 Gentle breeze 0.6 Large wavelets. Crests begin to break; scattered whitecaps 4 13-17 Moderate breeze 1 Small waves 5 18-24 Fresh breeze 2 Moderate (1.2 m) longer waves. Some foam and spray. 6 25-30 Strong breeze 3 Large waves with foam crests and some spray. 7 31-38 High wind 4 Sea heaps up and foam begins to be blown in streaks in wind direction.
