Sep-Oct

The window
Shoulder desert days stay warm at noon while nights fall hard after sunset.
October afternoons on the canyon floor can still feel soft. The mistake is packing only for that hour. When the sun leaves the walls, the temperature drops fast enough to end a rim walk early.
Practical
Keep a warm layer in the daypack, not in the car. The car is often a shuttle ride or a long walk from where the cold hits.
Prepare
Sun protection still matters at midday. The same day can ask for a hat at noon and a fleece at dusk.
