Due to the {{convert|6750|ft|m}} elevation<ref>{{cite web|url=https://www.freemaptools.com/elevation-finder.htm|title=Elevation Finder|publisher=FreeMapTools|access-date=July 27, 2021}}</ref> of the weather station, precipitation is greater than in the lowlands of southern California, averaging {{nowrap|{{convert|19.98|in|abbr=on}}}} a year. The maximum 24-hour precipitation was {{nowrap|{{convert|9.43|in|abbr=on}}}} on December 6, 1966. Measurable precipitation normally occurs 43.3 days a year. Mountain thunderstorms can produce heavy rainfall, even in midsummer (when most southern California lowland locations are quite dry). Under the [[Köppen climate classification]], Big Bear Lake has a warm-summer [[Mediterranean climate]] (''Csb'') bordering a [[humid continental climate]] (''Dsb''); it lies within USDA plant [[hardiness zone]] 7a.<ref>{{cite web|url=https://www.plantmaps.com/interactive-california-2012-usda-plant-zone-hardiness-map.php|title=California 2012 USDA Hardiness Zone Map|website=plantmaps.com|access-date=July 27, 2021}}</ref> Big Bear Lake is the highest and coldest incorporated city in southern California.<ref>{{cite web|url=http://www.totalescape.com/destin/townelevations.html#.YxT4EnbMIaQ|title=California Towns Listed by Elevation|publisher=Total Escape|access-date=September 4, 2022}}</ref>

In contrast to most of southern California, the Big Bear Lake region normally receives significant winter snow because of its high elevation. Snowfall, as measured at lake level, averages {{convert|58.6|in|cm|abbr=on}} per season; upwards of {{convert|100|in|cm|abbr=on}} can accumulate on the forested ridges bordering the lake, at elevations above {{convert|8000|ft|abbr=on}}. In February 1990, {{convert|59.5|in|cm|abbr=on}} of snow were recorded. The most snow in 24 hours was {{convert|27.0|in|cm|abbr=on}} on March 27, 1991. The greatest snow depth was {{convert|58|in|cm|abbr=on}} on February 3, 1979. Snow has fallen in every month except July and August. There are normally 16 days each year with measurable snow of {{convert|0.1|in|cm|abbr=on}} or more.
