Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Stephenson receives roughly an uncharted amount of precipitation each year, predominantly as rainfall. The frost-free season averages 128 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 22 and the first fall freeze near September 27. For energy use, 8,320 heating degree days and 321 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Stephenson scores 39/100 (Below Average), 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 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.
