What December feels like
Las Noches de las Luminarias at the Desert Botanical Garden sells out weeks ahead — thousands of paper lanterns along the cactus paths, and it lives up to the reputation. Days stay mild enough for shirtsleeves, but the cool mornings and the occasional soaking will surprise anyone expecting nothing but sun.
Real rain shows up about 2 days all month; the rest stay dry. The air runs dry — whatever the thermometer says, it wears easy.
