Sublime climate there, albeit not entirely (8)
I believe the answer is:
ethereal
'sublime' is the definition.
(I've seen this before)
'climate there albeit not entirely' is the wordplay.
'not entirely' indicates a hidden word.
'ETHEREAL' is hidden within 'climate there albeit'.
(Other definitions for ethereal that I've seen before include "'Extremely delicate, almost not of this world (8)'" , "Insubstantial or not of this world" , "exquisitely airy" , "Refined, airy" , "Take ale there: it's light and delicate" .)
