How can I describe this sky, in 3 letters as per the Aerodrome actual weather - METAR decode?

I found online a comprehensive list of Metar codes

    $\begingroup$ Looks like Broken (BKN) to me, but you also need to provide base altitude, so just BKN doesn't accurately describe the picture. $\endgroup$

1 Answer 1


This work sheet may be of use and generally the system of Okta is used to denote coverage in a Metar, but I would say

L1 Clouds: Cumulus (Cu) with little vertical extent

but it could also be

L5 Clouds: Stratocumulus (Sc) not from spreading out of Cumulus (Cu)

But I will agree with Ron on this one, its BKN (5-6 Okta based on the picture in my opinion)
