The NOAA 1991–2020 climate normals describe Ottumwa Industrial, Iowa as a location with an annual average temperature of 51°F, ranging from a mean daily high of 61°F to a mean daily low of 40°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00014950, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Ottumwa Industrial receives roughly 37.0 inches of precipitation each year, with 23.6 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near April 23 and the first fall freeze near October 14. For energy use, 6,145 heating degree days and 985 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Ottumwa Industrial scores 62/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
