These thirty-year averages, computed from station USC00452542, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Eltopia sees about 10.0 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 184 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 21 and the first fall freeze near October 22. On the energy side, 5,309 heating degree days and 543 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Eltopia scores 58/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and December-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
