I found this,"Mackerel sky, mackerel sky. Never long wet and never long dry."

[scooping]

thought it was mackerel sky, never long wet, never long dry.

[EDDIE51]

I know it as
Mackerel sky,mackerel sky, never long wet and never long dry
That does not fit but the answer will be similar , there are a few versions.

Perhaps this may help?

[Tilly2]

and...... Mackerel sky; not 24 hours dry.

Neither of which fit your pattern. :-(

Perhaps it's, Mackerel sky, mackerel sky, days wet, days dry.

not sure how it fits your puzzle though

You need to find a 4 letter word meaning never.
Anyone have a suggestion ?

[woofgang]

[Old_Geezer]

Did wonder. Seems a stretch though (or not depending on how you look at it).
