Some frigid temps (5)
I believe the answer is:
teens
'some frigid temps' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for teens that I've seen before include "Adolescent years" , "Between 12 and 20" , "13-19 age group" , "The years 13 to 19" , "Years 13-19" .)
