August is typically the warmest month of the year, while January is the coldest.

Anyone planning to live, garden, or travel in San Manuel should weigh precipitation alongside temperature: the annual average runs 22.9 inches, predominantly as rainfall. The frost-free season averages -24 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 25 and the first fall freeze near January 1. And on the energy front, 720 heating degree days and 4,133 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, San Manuel scores 84/100 (Excellent), 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 January-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.
