Anyone planning to live, garden, or travel in Lake Arrowhead should weigh precipitation alongside temperature: the annual average runs 37.7 inches, with 22.4 inches typically falling as snow. The frost-free season averages 181 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 5 and the first fall freeze near November 2. And on the energy front, 5,433 heating degree days and 401 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Lake Arrowhead scores 63/100 (Good), 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 August-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.
