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.
