Providing temperature in New York is fine (5)
I believe the answer is:
nifty
'fine' is the definition.
(thesaurus)
'providing temperature in new york' is the wordplay.
'providing' becomes 'if' (I've seen this in other clues).
'temperature' becomes 't' (abbreviation).
'in' is an insertion indicator.
'new york' becomes 'ny'.
'if'+'t'='ift'
'ift' inserted into 'ny' is 'NIFTY'.
'is' is the link.
(Other definitions for nifty that I've seen before include "Really good (slang)" , "Smart" , "Slick" , "Quick - stylish" , "Stylish; agile (informal)" .)
