Wind speed (Knots)
Label
Effect at sea
Effect on land
Wind speed (Knots):
1
Label:
Calm
Effect at sea:
Smooth and mirror-like.
Effect on land:
Calm. Smoke rises vertically.
Wind speed (Knots):
1-3
Label:
Light air
Effect at sea:
Small ripples, but no foam.
Effect on land:
Direction shown by smoke drift but not by wind vanes.
Wind speed (Knots):
4-6
Label:
Light breeze
Effect at sea:
Small but more pronounced wavelets. Ridges of glassy appearance.
Effect on land:
The wind is felt on the skin and the leaves of the trees move.
Wind speed (Knots):
7-10
Label:
Gentle breeze
Effect at sea:
Large wavelets, breaking ridges. Foam with glassy appearance. Scattered whitecaps may be present.
Effect on land:
Leaves and small twigs in constant motion; light flags extended.
Wind speed (Knots):
11-15
Label:
Moderate breeze
Effect at sea:
Small waves becoming longer; fairly frequent white horses.
Effect on land:
Raises dust and loose paper; small branches moved.
Wind speed (Knots):
16-21
Label:
Fresh breeze
Effect at sea:
Moderate waves taking a more pronounced long form; many white horses are formed; chance of some spray
Effect on land:
Small trees in leaf begin to sway; crested wavelets form on inland waters.
Wind speed (Knots):
22-27
Label:
Strong breeze
Effect at sea:
Large waves begin to form; the white foam crests are more extensive everywhere; probably some spray
Effect on land:
Large branches in motion; whistling heard in telegraph wires; umbrellas used with difficulty.
Wind speed (Knots):
28-33
Label:
High wind, moderate gale
Effect at sea:
Sea heaps up and white foam from breaking waves begins to be blown in streaks along the direction of the wind; spindrift begins to be seen
Effect on land:
Whole trees in motion; inconvenience felt when walking against the wind.
Wind speed (Knots):
34-40
Label:
Gale, fresh gale
Effect at sea:
Moderately high waves of greater length; edges of crests break into spindrift; foam is blown in well-marked streaks along the direction of the wind.
Effect on land:
Twigs break off trees; generally impedes progress. Cars turn sharply.
Wind speed (Knots):
41-47
Label:
Strong / severe gale
Effect at sea:
High waves; dense streaks of foam along the direction of the wind; sea begins to roll; spray affects visibility.
Effect on land:
Larger tree branches start to break, and some small trees are blown away by the wind. Construction/temporary signs and barriers are also blown away by the wind. Damage to circus tents and canopies.
Wind speed (Knots):
48-55
Label:
Storm, whole gale
Effect at sea:
Very high waves with long overhanging crests; resulting foam in great patches is blown in dense white streaks along the direction of the wind; on the whole the surface of the sea takes on a white appearance; rolling of the sea becomes heavy; visibility affected.
Effect on land:
Trees are broken or uprooted, shoots are twisted and deformed. Poorly laid tiles and shingles in poor condition detach from the roof.
Wind speed (Knots):
56-63
Label:
Violent storm
Effect at sea:
Exceptionally high waves; small- and medium-sized ships might be for a long time lost to view behind the waves; sea is covered with long white patches of foam; everywhere the edges of the wave crests are blown into foam; visibility affected.
Effect on land:
Widespread damage to vegetation. Further damage to most roofs, tiles that have broken or come off could split completely.
Wind speed (Knots):
64-71
Label:
Hurricane force
Effect at sea:
The air is filled with foam and spray; sea is completely white with driving spray; visibility very seriously affected.
Effect on land:
Significant and widespread damage to vegetation, some broken windows, structural damage to mobile homes and poorly constructed sheds and barns. Debris could be blown into the air.
