What Garden Valley's climate means for you
Garden Valley runs 47°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.
Based on station USC00103448 feeding NOAA's 1991–2020 climate normals, Garden Valley, Idaho averages 47°F a year, ranging from a mean daily high of 61°F to a mean daily low of 33°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.
Anyone planning to live, garden, or travel in Garden Valley should weigh precipitation alongside temperature: the annual average runs 26.6 inches, with 69.4 inches typically falling as snow. The frost-free season averages 101 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near June 1 and the first fall freeze near September 10. And on the energy front, 6,913 heating degree days and 292 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Garden Valley 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.
