What Las Vegas's climate means for you
Las Vegas runs 69°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 69°F, ranging from a mean daily high of 81°F to a mean daily low of 57°F is what the NOAA 1991–2020 climate normals report for Las Vegas, Nevada. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00264439 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. Las Vegas sees about 4.8 inches of precipitation a year, with negligible snowfall. The frost-free season averages 304 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 4 and the first fall freeze near December 5. On the energy side, 2,017 heating degree days and 3,563 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Las Vegas scores 80/100 (Excellent), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings December-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
