Weather in Azores is terrific (6)
I believe the answer is:
resist
'weather' is the definition.
(I know this)
'in azores is terrific' is the wordplay.
'in' indicates the answer is hidden within the clue.
'RESIST' is hidden in the letters of 'azores is terrific'.
(Other definitions for resist that I've seen before include "Oppose or fight against someone" , "Combat" , "Take stand against, oppose" , "Put up opposition, defy" , "Sister (anag)" .)
