In
meteorology, an
okta is a
unit of measurement used to describe the amount of
cloud cover at any given location such as a
weather station.
Sky conditions are estimated in terms of how many eighths of the sky are covered in
cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely
overcast).
When used in weather charts, okta measurements are shown by means of graphic symbols (rather than numerals) contained within weather circles, to which are attached further symbols indicating other measured data such as wind speed and wind direction.
[1]Oktas are often referenced in
aviation weather forecasts and low level forecasts: SKC = sky clear; FEW = 1 to 2 oktas; SCT = 3 to 4 oktas; BKN = 5 to 7 oktas; OVC = 8 oktas; NSC = nil significant cloud; CAVOK = ceiling and visibility okay.

Czyli równie dobrze moglibyśmy zmienić nazwe na OVERCAST albo 8 OKTA
