Saguaro in January: what the park service says
January is Saguaro's mild season. The park service puts winter days at about 65°F on average with nights near 40°F, and many ranger-led programs run through the winter. Higher up in the Rincon Mountains snow is common, and drifts can make trails there impassable, and in wet winters that snow can persist for months. Down on the desert floor, an occasional snowfall usually melts by the afternoon.
