What Mercury Desert Rock's climate means for you
Mercury Desert Rock runs 64°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
An annual average temperature of 64°F, ranging from a mean daily high of 77°F to a mean daily low of 50°F is what the NOAA 1991–2020 climate normals report for Mercury Desert Rock, Nevada. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USW00003160 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Mercury Desert Rock receives roughly 5.2 inches of precipitation each year, with 1.0 inches typically falling as snow. The frost-free season averages 246 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near March 16 and the first fall freeze near November 17. For energy use, 2,842 heating degree days and 2,331 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Mercury Desert Rock scores 77/100 (Good), 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 December-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.
