|---|---|---|---|---|---|---|
| 0 | <1 | <2 | Sea surface smooth and mirror-like | Calm, smoke rises vertically | Calm | |
| 1 | 1-3 | 1-5 | 0.25 | Scaly ripples, no foam crests | Smoke drift indicates wind direction, still wind vanes | Light air |
| 2 | 4-6 | 6-11 | 0.5-1 | Small wavelets, crests glassy, no breaking | Wind felt on face, leaves rustle, vanes begin to move | Light breeze |
| 3 | 7-10 | 12-19 | 2-3 | Large wavelets, crests begin to break, scattered whitecaps | Leaves and small twigs constantly moving, light flags extended | Gentle breeze |
| 4 | 11-16 | 20-29 | 3.5-5 | Small waves becoming longer, numerous whitecaps | Dust, leaves, and loose paper lifted, small tree branches move | Moderate breeze |
| 5 | 17-21 | 30-39 | 6-8 | Moderate waves taking longer form, many whitecaps, some spray | Small trees in leaf begin to sway | Fresh breeze |
| 6 | 22-27 | 40-50 | 9.5-13 | Larger waves, whitecaps common, more spray | Larger tree branches moving, whistling in wires | Strong breeze |
| 7 | 28-33 | 51-61 | 13.5-19 | Sea heaps up, white foam streaks off breakers | Whole trees moving, resistance felt walking against wind | Near gale |
| 8 | 34-40 | 62-74 | 18-25 | Waves of gr. length, edges of crests break into spindrift, foam blown in streaks | Whole trees in motion, resistance felt walking against wind | Gale |
| 9 | 41-47 | 76-87 | 23-32 | Sea begins to roll, dense streaks of foam, spray may reduce visibility | Slight structural damage occurs, slate blows off roofs | Strong gale |
| 10 | 48-55 | 88-102 | 29-41 | Waves with overhanging crests, sea white with densely blown foam, heavy rolling | Seldom experienced on land, trees broken or uprooted, consid. structural damage | Storm |
| 11 | 56-63 | 103-118 | 37-52 | Exceptionally high waves, foam patches cover sea, visibility more reduced | Violent storm | |
| 12 | >64 | >119 | >45 | Air filled with foam, sea completely white with driving spray | Hurricane |
