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 0% of days and daytime highs near 35.0°C (95°F). January is the wettest, at 35%. Temperature swings hard across the year — 24.6°C between July (35.0°C / 95°F) and January (10.4°C / 51°F) — so packing for the wrong month is the main risk. The record rules out too hot in Jul–Aug.
