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.
April is the driest month, with rain on 19% of days and daytime highs near 29.7°C (85°F). September is the wettest, at 76%. Temperature barely moves all year — just 3.6°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in Jun–Nov.
