from Martins excellent FAQ

"Provided the visibility is =10 km, AND the height of the lowest cloud (any
amount) is =5000 ft (or highest minimum sector altitude) AND there are no
cumulonimbus clouds (CB, any height) within sight AND there is no
significant weather (see list below), then the visibility and cloud part of
the standard METAR is replaced by CAVOK (say "cav-oh-kay": 'Ceiling And
Visibility OK'). (not used by certain countries, e.g. the United States)"
