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 9% of days and daytime highs near 30.9°C (88°F). August is the wettest, at 87%. Temperature barely moves all year — just 4.0°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in May–Oct.
