Beaufort Wind Scale | | Force | Wind Speed | Description | Effects Land / Sea | | mph | km/hr | knots | | 0 | <1 | <1 | <1 | Calm | Still, calm air, smoke will rise vertically. Water is mirror-like. | | 1 | 1-3 mph | 1-5 kph | 1-3 knots | Light Air | Rising smoke drifts, wind vane is inactive. Small ripples appear on water surface. | | 2 | 4-7 mph | 6-11 kph | 4-6 knots | Light Breeze | Leaves rustle, can feel wind on your face, wind vanes begin to move. Small wavelets develop, crests are glassy. | | 3 | 8-12 mph | 12-19 kph | 7-10 knots | Gentle Breeze | Leaves and small twigs move, light weight flags extend. Large wavelets, crests start to break, some whitecaps. | | 4 | 13-18 mph | 20-28 kph | 11-16 knots | Moderate Breeze | Small branches move, raises dust, leaves and paper. Small waves develop, becoming longer, whitecaps. | | 5 | 19-24 mph | 29-38 kph | 17-21 knots | Fresh Breeze | Small trees sway. White crested wavelets (whitecaps) form, some spray. | | 6 | 25-31 mph | 39-49 kph | 22-27 knots | Strong Breeze | Large tree branches move, telephone wires begin to "whistle", umbrellas are difficult to keep under control. Larger waves form, whitecaps prevalent, spray. | | 7 | 32-38 mph | 50-61 kph | 28-33 knots | Moderate or Near Gale | Large trees sway, becoming difficult to walk. Larger waves develop, white foam from breaking waves begins to be blown. | | 8 | 39-46 mph | 62-74 kph | 34-40 knots | Gale or Fresh Gale | Twigs and small branches are broken from trees, walking is difficult. Moderately large waves with blown foam. | | 9 | 47-54 mph | 75-88 kph | 41-47 knots | Strong Gale | Slight damage occurs to buildings, shingles are blown off of roofs. High waves (6 metres), rolling seas, dense foam, Blowing spray reduces visibility. | | 10 | 55-63 mph | 89-102 kph | 48-55 knots | Whole Gale or Storm | Trees are broken or uprooted, building damage is considerable. Large waves (6-9 metres), overhanging crests, sea becomes white with foam, heavy rolling, reduced visibility. | | 11 | 64-72 mph | 103-117 kph | 56-63 knots | Violent Storm | Extensive widespread damage. Large waves (9-14 metres), white foam, visibility further reduced. | | 12 | 73+ mph | 118+ kph | 64+ knots | Hurricane | Extreme destruction, devastation. Large waves over 14 metres, air filled with foam, sea white with foam and driving spray, little visibility. |
