Be wet — then area unfortunately showing effect of climate (7-6)
I believe the answer is:
weather-beaten
'showing effect of climate' is the definition.
'be wet then area unfortunately' is the wordplay.
'unfortunately' indicates an anagram.
'be'+'wet'+'then'+'area'='bewetthenarea'
'bewetthenarea' anagrammed gives 'WEATHER-BEATEN'.
(Other definitions for weather-beaten that I've seen before include "Well-seasoned" , "Damaged by storms, etc" , "Worn by the elements" , "Tanned and coarsened from being outdoors" , "Rugged" .)
