Across a typical year, afternoon temperatures swing between 14°C (January) and 29°C (July). The wet–dry contrast is modest: 35% rain-day odds in September against 13% in January. The genuinely warm window — average highs of 24°C or better — covers June–September.

Averaged by season, sun scores land at 82 for spring, 98 for summer, 82 for autumn and 63 for winter — with typical afternoons of 19°, 28°, 22° and 15°C respectively.
