Ulysses, KS Climate

Climate Insight: Ulysses, KS

Based on station USC00148287 feeding NOAA's 1991–2020 climate normals, Ulysses, Kansas averages 54°F a year, ranging from a mean daily high of 69°F to a mean daily low of 39°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. Ulysses sees about 17.8 inches of precipitation a year, with 17.8 inches typically falling as snow. The frost-free season averages 171 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 16. On the energy side, 5,263 heating degree days and 1,286 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Ulysses scores 54/100 (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.
