Ignore symptom Spooner reports in good weather (8)
I believe the answer is:
sunshine
'good weather' is the definition.
(pleasant weather)
'ignore symptom spooner reports in' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
This explanation may well be incorrect...
(Other definitions for sunshine that I've seen before include "Brightness" , "In US hens is found this light" , "Solar rays" , "Is she nun out in the fine weather" , "Ironic address (as of policeman to young offender)" .)
