What South Lake Tahoe's climate means for you
South Lake Tahoe runs 44°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
An annual average temperature of 44°F, ranging from a mean daily high of 59°F to a mean daily low of 29°F is what the NOAA 1991–2020 climate normals report for South Lake Tahoe, California. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USW00093230 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
South Lake Tahoe averages 20.5 inches of precipitation a year, predominantly as rainfall, and that matters as much to daily life here as temperature does. Growing-season length varies with elevation and microclimate. As for energy demand, 7,599 heating degree days and 29 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, South Lake Tahoe scores 57/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings December-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
