Due to the 6,790 foot (2,069 m) elevation of the weather station, precipitation is greater than in the lowlands of San Bernardino County, averaging 21.15 in (537.21 mm) a year. The maximum 24-hour precipitation was 9.43 in (239.52 mm) on December 6, 1966. Measurable precipitation normally occurs 44.9 days a year. Mountain thunderstorms, originating from the westernmost edge of the North American Monsoon, occasionally produce heavy rainfall, even in midsummer (when most southern California lowland locations are quite dry). This produces a distinct increase in precipitation in July and August, but total rainfall is still low as it is throughout the summer. Big Bear Lake's climate is Csb under the K�ppen climate classification, often described as Warm Summer Mediterranean.

The Big Bear Lake region is unique among populated areas in Southern California in that, because of the elevation, it normally receives significant winter snow. Snowfall, as measured at lake level, averages 61.8 inches (157 cm) each year (although upwards of 100 inches (254 cm) can accumulate on the forested ridges bordering the lake, above 8,000 feet (2,400 m). In February 1990, 59.5 inches (151 cm) of snow were recorded. The most snow in 24 hours was 27.0 inches (69 cm) on March 27, 1991. The greatest snow depth was 58 inches
