Near; muggy (5)

I believe the answer is:

I believe this is a double definition.

'near' is the first definition.
(similar in meaning)

'muggy' is the second definition.
(thesaurus)

(Other definitions for close that I've seen before include "residential street" , "Meeting with a UFO?" , "Tightly" , "Dense; nearby" , "cathedral precinct" .)

I've seen this clue in The Telegraph.
