Verdict combines mean daytime high with rainy-day frequency. “Rainy days” is the share of days in the month with at least 1 mm of rain.
July is the driest month, with rain on 12% of days and daytime highs near 26.1°C (79°F). November is the wettest, at 94%. Temperature barely moves all year — just 2.4°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in Sep–May.
