'august perhaps' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'saying hello to adder' is the wordplay.
'saying' indicates a 'sounds like' (homophone) clue.
'hello' becomes 'hi' (synonyms).
'to adder' becomes 'summer' (someone adding up or doing sums).
'hi' is a homophone of 'high'.
'high'+'summer'='HIGH SUMMER'

'in' is the link.
