No. MPH KmPH Status Sea Land
0 < 1 < 1.6 CALM Flat calm, like a mill pond. Calm. Smoke will rise vertically.
1  1 - 3  1.6 - 4.8 LIGHT AIR Ripples with the appearance of scales; no foam crests. Calm. Rising smoke drifts, weather vane is inactive
2  4 - 7  6.4 - 11.3 LIGHT BREEZE Small wavelets; crests of glassy apprearance, not breaking. Calm.  Leaves rustle, can feel wind on your face, weather vane begins to move.
3  8 - 12   12 - 19 GENTLE BREEZE Large wavelets; crests begin to break; scattered whitecaps. Smooth. Leaves and twigs move around. Light weight flags extend.
4  13 - 18   20 - 30 MODERATE BREEZE Small waves, becoming longer; numerous whitecaps. Slight.  Moves thin branches, raises dust and paper.
5  19 - 24  30 - 39 FRESH BREEZE Moderate waves, taking longer form; many whitecaps; some spray. Moderate. Trees sway. 
6  25 - 31  40 - 50 STRONG BREEZE
Larger waves forming; whitecaps everywhere; more spray. Rough. Large tree branches move, open wires (such as telegraph wires) begin to "whistle", umbrellas are difficult to keep under control.
7  32 - 38  51 - 61 MODERATE GALE Sea heaps up; white foam from breaking waves begins to blow in streaks. Very Rough. Large trees begin to sway, noticeably difficult to walk. 
8  39 - 46  62 - 74 FRESH GALE Moderately high waves of greater length; edges of crests begin to break into spindrift; foam is blown into wellmarked streaks. Very Rough. Twigs and small branches are broken from trees, walking into the wind is very difficult.
 47 - 54  75 - 87 STRONG GALE High waves; seas begins to roll; dense streaks of foam; spray may reduce visibility. Very Rough. Slight damage occurs to buildings, shingles are blown off of roofs.
10  55 - 63  88 - 101 STORM Very high waves with overhanging crests; sea takes white appearance as foam is blown in very dense streaks; rolling is heavy and visibility is reduced.
Large trees are uprooted, building damage is considerable
11  64 - 72 102 - 116 VIOLENT STORM Exceptionally high waves; sea covered with white foam patches; visibility still more reduced. Extensive widespread damage. These typically occur only at sea, and rarely inland.
12  73 > 116 > HURRICANE Air filled with foam; sea completely white with driving spray; visibility still more reduced. Extreme destruction.

The term "squall" is used to refer to a sudden wind-speed increase, both historically and in the present day. In 1962 the World Meteorological Organization (WMO) defined that to be classified as a squall, the wind must increase at least 8 m/s (17.9 mph) and must attain a top speed of at least 11 m/s (24.6 mph), lasting at least one minute in duration
