Big Water, UT Climate

Climate Insight: Big Water, UT

An annual average temperature of 58°F, ranging from a mean daily high of 72°F to a mean daily low of 44°F is what the NOAA 1991–2020 climate normals report for Big Water, Utah. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00420688 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. Big Water sees about 7.7 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 207 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 8 and the first fall freeze near November 1. On the energy side, 4,353 heating degree days and 1,682 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Big Water scores 58/100 (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.
