What July feels like
The monsoon is the event of the Tucson year and people mean it — storms build over the Catalinas most afternoons and locals drive out to Gates Pass to watch them come in. Wash crossings flood fast and those signs are not decorative; turn around rather than test one. Afterward the whole city smells like creosote, which is what everyone here means when they say rain.
Expect about 5 days with real rain — enough to notice, not enough to plan around. Humidity stays comfortable; the air never feels heavy. Most afternoons push past 90°.
