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.
February is the driest month, with rain on 7% of days and daytime highs near 30.2°C (86°F). July is the wettest, at 84%. Temperature barely moves all year — just 3.2°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in May–Nov.
