Jump season (6)

I believe the answer is:

spring

I believe this clue is a double definition.

'jump' is the first definition.
(spring is a kind of jump)

'season' is the second definition.
(spring is a kind of season)

(Other definitions for spring that I've seen before include "Schumann symphony" , "warp" , "Wellhead or bounce" , "Mechanical device" , "May, perhaps - bound" .)

I've seen this clue in The Telegraph and The Independent.
