Saguaro in December: what the park service says

December brings Saguaro's winter rains and, in the mountains, snow. The park says snow occasionally dusts the desert floor but melts fast in the afternoon, while at higher elevations it is common and can last for months in a wet winter. Slow snowmelt seeps into the aquifers, and the park calls snow one of the most important water sources in the desert.
