About California Winter Weather
California sits in the classic mid-latitude winter belt — enough snow to regularly close schools, not enough to build infrastructure for it. Across the 25 California cities covered by SnowSense™, average annual snowfall is 23 inches. Mammoth Lakes receive up to 240 inches in a typical winter; lower-latitude cities like Los Angeles see closer to 0.
School-closure decisions in California often hinge on precipitation type as much as accumulation. Storms that cross the region frequently transition from snow to sleet to freezing rain and back, and the difference between a four-inch snow event and a one-inch ice-glaze event is invisible until the storm arrives. Districts tend to close preemptively when ice risk is in the forecast.
