Graphical Climatology of Las Vegas Temperatures, Precipitation, and other Variables (1937-Present)
The following is a graphical climatology of Las Vegas, Nevada area temperatures, precipitation, and various other parameters, from 1937 into 2026. Presented are daily climatological overview charts (temperature), annual time-series (temperature and precipitation), “climograms” (hour-by-month depictions of temperature, humidity, winds, fog, blowing sand/dust, and thunderstorms), followed by year-to-year graphs that depict daily max/min temperature, daily mean temperature anomalies, daily rainfall, and when applicable daily snowfall/depths. Data were obtained courtesy of the NOAA National Climatic Data Center and the NWS- Las Vegas online site.

Year-To-Year Graphs:
The year-to-year daily graphs pages (links below) consist of four charts tiled horizontally. The uppermost graph displays “floating-bars” or “hi-lo” depictions of the daily maxima and minima. Each bar represents an individual day’s temperature range. Superimposed are two line traces, the upper one connecting average daily maxima, the lower one average daily minima. The bars depict the varying diurnal, synoptic, long-wave, and seasonal influences on temperature over time.
The second chart down shows the arithmetic departures of day-to-day mean temperatures less the corresponding calendar-day average means. Red lines extending upward from the zero line indicate above average means for the day, blue ones extending downward depicting below average ones.
The third chart down shows the second chart’s departures in deseasonalized or “standardized” form. Standardized anomalies are calculated by dividing the arithmetic departure by the climatological mean temperature standard deviation for the calendar day in question, creating “z-scores”. Through 2023, the most extreme z-score is -4.59 z, for 22 January 1937
The fourth chart down depicts daily rainfall, as high as 2.58 inches (21 August 1957 ), the fifth shows snowfall, as high as 7.4 inches (31 January 1979), and the sixth snow depth, as high as 8 inches (5 January 1974).
