When one can expect a chilly reception? (4,6)

'when one can expect a' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'chilly reception?' is the wordplay.
I cannot quite see how this works, but
'chilly' could be 'cold' (I've seen this in another clue) and 'cold' is found in the answer.
The remaining letters 'season' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
