An "okta" simply means an eighth. So if there are 4 oktas of cloud, it
means that the sky is half covered. I don't believe that there's any way
of measuring the amount of cloud cover other than human judgement, but I
could be wrong.

I see that the term doesn't seem to be included in the Glossary section
of Martin Rowley's excellent FAQ:

However, it _is_ defined he

.... yes, I made the decision some years ago that I wouldn't put *all*
items such as this in the Glossary (or it would get too unwieldy), so
went the way of providing an index ('Alpha-Index') which you can access
via the main page for the FAQ, Glossary etc. at:-

http://homepage.ntlworld.com/booty.weather/uswfaqfr.htm

or via my 'Met' home page at:-

One day I'll get around to putting a search facility on the site ....
one day ;-)

Martin.

Okta is another word for eighth. Observers divide the sky into eighths to
establish cloud cover. Half sky covered 4/8ths or 4 oktas
