Climate Insight: Delavan Wwtp, WI
Based on station USC00472051 feeding NOAA's 1991–2020 climate normals, Delavan Wwtp, Wisconsin averages 48°F a year, ranging from a mean daily high of 58°F to a mean daily low of 38°F. July is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Delavan Wwtp sees about 36.7 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 169 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 28 and the first fall freeze near October 14. On the energy side, 6,933 heating degree days and 631 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Delavan Wwtp scores 64/100 (Good), 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 January-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.
