What Sugar City's climate means for you
Sugar City runs 43°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
An annual average temperature of 43°F, ranging from a mean daily high of 57°F to a mean daily low of 29°F is what the NOAA 1991–2020 climate normals report for Sugar City, Idaho. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00108818 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Sugar City averages an uncharted amount of precipitation a year, predominantly as rainfall, and that matters as much to daily life here as temperature does. The frost-free season averages 107 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 29 and the first fall freeze near September 13. As for energy demand, 8,210 heating degree days and 118 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Sugar City scores 39/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
