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.
July is the driest month, with rain on 3% of days and daytime highs near 29.0°C (84°F). November is the wettest, at 97%. Temperature barely moves all year — just 2.6°C between the warmest and coolest months — so rainfall, not heat, decides when to go. The record rules out too wet in Oct–May.
