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.
August is the driest month, with rain on 23% of days and daytime highs near 24.8°C (77°F). April is the wettest, at 86%. Temperature barely moves all year — just 2.9°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in Nov–May.
