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.
December is the driest month, with rain on 13% of days and daytime highs near 29.6°C (85°F). June is the wettest, at 93%. 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 Apr–Oct.
