I felt it was a pretty standard August for Christchurch. Seemed like more frosts and colder mornings, but Tmax probably running around average. Tmin slightly lower? Rainfall should have been under average from my feelings.
Pretty standard end of winter, looking forward to September and some spring conditions

After 2 exceptionally warm winter months, August 2023 looks to be NZ's coldest winter month since 2017 and coldest August since 2016. It was, however, also a generally relatively dry and sunny month for most parts.
