Naples, Italy

July is the heat peak, averaging 31°C highs; January is the cool end, when nights dip to around 6°C. The wet–dry contrast is pronounced: 51% rain-day odds in November against 12% in July. The genuinely warm window — average highs of 24°C or better — covers June–September.

Averaged by season, sun scores land at 80 for spring, 98 for summer, 79 for autumn and 55 for winter — with typical afternoons of 19°, 30°, 22° and 14°C respectively.
