Monsoon-Aware
9 destinations along 8 roads
From roughly July into September the Southwest runs on the monsoon — humid mornings that build into hard afternoon thunderstorms, often over ground miles from where the rain lands. That's the danger: a dry slot canyon can flash-flood from a storm you never see, and dirt roads turn to grease in minutes. Watch the sky, check the forecast, and be out of the narrows and off the clay before the afternoon builds. The storms bring the best light of the year — and its real hazard.
