1 - 22
Sea conditions
- Sea is like a mirror.
- Ripples with appearance of scale, no foam
crests.
- Short wavelets, but pronounced.
- Very small waves, crests begin to break.
- Small waves, becoming longer, numerous
whitecaps.
- Wavelets form on inland waters; moderate
waves, taking longer form.
- Larger waves forming, whitecaps everywhere,
some spray.
- Sea heaps up; white foam from breaking
waves begins to be blown in streaks along
the direction of the wind.
- Moderately high waves of greater length;
edges of crests begin to break into spindrift.
- High waves, crests of waves begin to topple,
streaks of foam; reduced visibility.
- Very high waves; white streaks of foam;
reduced visibility.
- Exceptionally high waves able to hide medium
sized ships from view, reduced visibility.
- Sea completely white; air filled with foam and
spray, very reduced visibility.
