Hampton, IA Climate

Climate Insight: Hampton, IA

An annual average temperature of 47°F, ranging from a mean daily high of 57°F to a mean daily low of 36°F is what the NOAA 1991–2020 climate normals report for Hampton, Iowa. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00133584 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Hampton sees about 38.1 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 163 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 29 and the first fall freeze near October 9. On the energy side, 7,363 heating degree days and 712 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Hampton 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.
