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 3% of days and daytime highs near 30.5°C (87°F). September is the wettest, at 92%. Temperature barely moves all year — just 3.4°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in May–Oct.
