Peaceful surroundings of Tahiti? (7)
I believe the answer is:
pacific
I believe this clue is a double definition.
'peaceful' is the first definition.
(similar in meaning)
'surroundings of tahiti?' is the second definition.
(Tahiti is in the Pacific Ocean)
(Other definitions for pacific that I've seen before include "Ocean; peaceful" , "mild" , "Peaceful in character" , "Calm - ocean" , "steam locomotive?" .)
