What December feels like
Winter rain shows up now, gently, and the Catalinas can go white overnight while town stays clear. Nights drop far enough that the citrus gets covered again, and the luminaria displays at the Botanical Gardens and through the Winterhaven streets draw slow-moving traffic every evening.
Real rain shows up about 3 days all month; the rest stay dry. The air runs dry — whatever the thermometer says, it wears easy.
