The Oktas scale is used to measure what?

• A. Cloud cover
• B. Wind speed
• C. Temperature
• D. Sunshine duration

Answer: (A)

The Oktas scale measures how much of the sky is covered by clouds. An observer divides the sky into eight equal parts and counts how many parts are cloudy. Each part is one okta, so the total ranges from 0 to 8. A reading of 0 means a clear sky, while 8 means a completely overcast sky. This quick, qualitative measure helps weather observers describe sky conditions in reports and forecasts. It’s specifically about cloud cover, not wind speed, temperature, or sunshine duration.
