What September feels like
Warm afternoons, cool evenings, and the maples up Big and Little Cottonwood going red well before the aspens do. The Greek Festival and the state fair both land this month, and the canyon trailheads are busy without being desperate.
Real rain shows up about 3 days all month; the rest stay dry. The air runs dry — whatever the thermometer says, it wears easy. about 5 afternoons top 90°.
