Las Vegas's normals sit in a dry climate class: BWh

Annual precipitation falls well below the aridity threshold for this temperature regime, so the normals classify as hot desert (BWh). Class BWh is the Peel et al. (2007) label for this station's monthly mean temperature and precipitation normals: dry (arid or semi-arid), specifically hot desert.

The year, day by day

The year in Las Vegas runs from a mild 37°F around December 20 to 106°F at the peak near July 14, and the normal low never reaches freezing on any date in the record.

When the heat sits

Normal highs reach 90°F from May 18 through September 29, covering 135 dates. The broader mild season, normal highs of 70°F or more, runs March 10 to November 10.

This counts calendar dates whose 1991–2020 normal high reaches 90°F. It is a smaller number than the 90°F+ day counts in the monthly table above, which measure how often the threshold was actually crossed in a typical year. A date can average 88°F and still exceed 90°F in half of all years.

No freezing date

Not one calendar date in the 1991–2020 record carries a normal low at or below 32°F. The coldest normal low of the year is 37°F around December 20.

Where the wet dates fall

The likeliest wet date is February 20, when 15% of years recorded at least a hundredth of an inch. The driest is June 4 at 2%. Summed across the calendar, that is about 29 wet dates a year.

The widest day

June 16 carries the biggest normal gap between afternoon and dawn, 28°F between the normal high and the normal low.

Where Las Vegas Stands Nationally

Summers here run among the most heat-heavy normals calendars in the country: on about 135 days a year the normal daily high itself reaches 90°F — a count fewer than one station in ten exceeds.

Aridity defines the water calendar: about 5 inches in a normal year lands this among the driest tenth of ranked stations.

Las Vegas earns 2 nationally notable standings (outer quintiles) against 6,860 NOAA 1991–2020 normals stations; only those extremes render.

Las Vegas's wet season runs through the cold months

December, January and February carry 41% of the year's precipitation here, while June through August contribute 19%. That is the cool-season-dominant pattern of the West Coast and the higher inland West, where storm tracks swing south in winter and summer turns dry; the thermometer meanwhile shows a wide 45.5°F gap between its warmest and coldest month.

Shares are computed from this station's own 1991-2020 monthly precipitation normals. A cool-season label means the December-February share reaches 35%. Where snow falls, the monthly figures above report liquid-equivalent precipitation, so a wet winter month is not necessarily a rainy one.

Las Vegas is dry, and what does fall arrives gently

Only about 29 days a year record measurable precipitation here, 8% of the calendar, and they carry 4.8" between them. At roughly 0.17 inches on an average wet day, this is not the damp drizzle of a marine climate; it is an arid record in which precipitation is both uncommon and light when it appears.

The wettest month by count is February at about 4 wet days; the driest is June at about 1.

A low per-event average in a dry record is a statement about typical days only. Arid regions can still take a large share of a year's total from a single convective storm, which a normal cannot show.

A wet day is one recording at least 0.01 inches. These are 1991-2020 normals: they describe an average year, not the extremes within it.

Snow reaches Las Vegas, but rarely amounts to much

The normals record 0.2 inches of snow a year here, most likely in December. That is a real but marginal amount: enough that snow is part of the local record, not enough to define the winter.

A figure in this range usually reflects a handful of events that melt quickly rather than a season of accumulation; about 0 days a year record any measurable snow at all.

NOAA 1991-2020 normals. An average across thirty years can smooth away a single heavy winter, so a small annual figure does not mean a significant snowfall is impossible.

Scarce-water calendar

Where Las Vegas's limited precipitation lands

mixed demand · dry · mid swing

Local precipitation is sparse in this otherwise mixed profile. The station reports 4.8 inches annually, within PlainClimate's dry band. Recorded annual snowfall is negligible. The monthly distribution matters because the total alone does not reveal the timing.

July and December mark the typical warm and cold ends of the calendar in Las Vegas's middle-range seasonal profile. The measured spread is 45.5°F. The annual average is 69°F. Neither the annual mean nor one extreme month represents the full calendar on its own.

Heating and cooling both register in Las Vegas's normal, at 2,017 and 3,563 degree days respectively. Neither total exceeds the other by more than two to one, so the record is better read as a mixed-demand calendar than as heating-led or cooling-led.

Las Vegas has a long frost-free window of roughly 304 days, but the dry annual profile is a separate constraint. Growing-season length says when freezes are unlikely, not whether rainfall is sufficient.

Questions about Las Vegas's climate

How dry is Las Vegas?
Las Vegas receives 4.8 inches of precipitation a year, spread across roughly 29 days that record any measurable amount. For reference, the contiguous United States averages near 30 inches. Based on NOAA 30-year climate normals (1991-2020).
How many days above 90°F does Las Vegas get?
Las Vegas averages about 138 days a year at or above 90°F, concentrated in July and the months either side of it. That is a count of days reaching the threshold, not a measure of how far above it they go.
How much energy does heating and cooling require in Las Vegas?
Las Vegas has 2,017 heating degree days and 3,563 cooling degree days annually, a fairly balanced heating/cooling split. Degree-day definitions: reading weather data.
