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.
January is the driest month, with rain on 43% of days and daytime highs near 24.2°C (76°F). May is the wettest, at 86%. Temperature barely moves all year — just 2.0°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in Mar–Dec.
