What to pack

What August feels like

Storms are rare here, but late summer is when they come, and in a landscape with nothing to absorb anything, a rare storm means flash floods that close roads and sometimes the whole park. Check road status before you drive in, and never park in a wash.

Rain is genuinely rare — most years, August stays dry start to finish. Most afternoons push past 90°.
