May is the driest month, with rain on 0% of days and daytime highs near 39.0°C (102°F). January is the wettest, at 5%. Temperature swings hard across the year — 20.4°C between July (42.6°C / 109°F) and January (22.2°C / 72°F) — so packing for the wrong month is the main risk. The record rules out too hot in Apr–Oct.
