Appearance of sea if fetch and duraction of the blow have been
sufficient to develop the sea fully |
Description |
00 |
Sea like a mirror |
Calm |
01 |
Ripples with the appearance
of scales are formed, but without foam crests |
Light air |
02 |
Small wavelets; crests
have a glassy appearance and do not break |
Light breeze |
03 |
Large wavelets; crests
begin to break; foam of glassy appearance; perhaps scattered white
horses |
Gentle breeze |
04 |
Small waves, becoming
longer; fairly frequent white horses |
Moderate breeze |
05 |
Moderate waves; many white
horses are formed (chance of some spray) |
Fresh breeze |
06 |
Large waves; white foam
crests everywhere (probably some spray) |
Strong breeze |
07 |
Sea heaps up and white
foam from breaking waves begins to be blown in streaks along the direction
of the wind |
Near gale |
08 |
Moderately high waves;
edges of crests begin to break into the spindrift; foam is blown in
well-marked streaks along the direction of the wind |
Gale |
09 |
High waves; dense streaks
of foam along wind; crests begin to topple, tumble and roll over;
spray may affect visibility |
Strong gale |
10 |
Very high waves with long
overhanging crests; foam in great patches blown in dense white streaks
along wind; sea surface takes a white appearance; tumbling becomes
heavy and shock-like; visibility affected |
Storm |
11 |
Exceptionally high waves
(medium sized ships may be lost to view behind waves); sea covered
with long white patches of foam lying along the wind; everywhere edges
of crests are blown into froth; visibility affected |
Violent storm |
12 |
Air is filled with foam
and spray; sea completely white with driving spray; visibility seriously
affected |

to the descriptive terms, these height values may be used for guidance
by the observer when reporting the total state of agitation of the sea
resulting from various factors such as wind, swell, currents, angle between
swell and wind, etc.
