Climate Insight: Jamestown Muni, ND

The NOAA 1991–2020 climate normals describe Jamestown Muni, North Dakota as a location with an annual average temperature of 41°F, ranging from a mean daily high of 52°F to a mean daily low of 31°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00014919, 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. Jamestown Muni receives roughly 19.8 inches of precipitation each year, predominantly as rainfall. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 11 and the first fall freeze near September 28. For energy use, 9,010 heating degree days and 419 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Jamestown Muni scores 47/100 (Moderate), 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.
