Anyone planning to live, garden, or travel in Aurora State should weigh precipitation alongside temperature: the annual average runs 39.5 inches, predominantly as rainfall. The frost-free season averages 243 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 16 and the first fall freeze near November 14. And on the energy front, 4,162 heating degree days and 455 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Aurora State scores 72/100 (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.
