Interlude in a bay (6)
I believe the answer is:
recess
I believe this is a double definition.
'interlude' is the first definition.
(thesaurus)
'a bay' is the second definition.
(bay can mean a coastal recess)
'in' is the link.
(Other definitions for recess that I've seen before include "Breaktime" , "Suspension of a session for a rest" , "Nook for a break from business" , "Official holiday break" , "Niche; temporary cessation of parliament" .)
