Beyond temperature, Zion NP averages 16.3 inches of precipitation annually, with 4.0 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 203 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 13 and the first fall freeze near November 2. Turning to energy use, 3,257 heating degree days and 2,211 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Zion NP scores 83/100 (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 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.
