Climate Insight: Rochford, SD
Based on station USC00397227 feeding NOAA's 1991–2020 climate normals, Rochford, South Dakota averages 39°F a year, ranging from a mean daily high of 56°F to a mean daily low of 22°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.
Beyond temperature, Rochford averages an uncharted amount of precipitation annually, predominantly as rainfall - a real factor for anyone planning to live, garden, or travel here. Growing-season length varies with elevation and microclimate. Turning to energy use, 9,565 heating degree days and 55 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Rochford scores 42/100 (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 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.
