How elevation shapes the reading in Las Vegas
Las Vegas is about 2,001 ft (610 m) above sea level. That is high enough that the air pressure you actually stand in is well below the figure in the forecast: about 27.82 inHg (942 hPa) on a standard day, against 29.92 inHg at sea level.
The reading above is the altimeter setting from Las Vegas/Reid Intl (KLAS), 12 km (7 mi) from the city center. It is the station’s measured pressure corrected to sea level, which is the number weather reports, apps and TV forecasts use, so you can compare Las Vegas with any other city.

Reading the barometer
What today’s pressure means for Las Vegas
High: above 30.20 inHg
Above about 1023 hPa. Sinking air under high pressure usually brings clear skies, light winds and, in winter, colder nights.
Normal: 29.80 – 30.20 inHg
About 1009–1023 hPa. Weather can go either way, so the 3-hour trend is the better guide.
Low: below 29.80 inHg
Below about 1009 hPa. Rising air under low pressure builds clouds; expect wind and rain, especially if the pressure keeps falling.
Frequently asked questions
What is the barometric pressure in Las Vegas today?
The live reading at the top of this page is the latest sea-level pressure reported by Las Vegas/Reid Intl (KLAS), 12 km (7 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Las Vegas?
Weather reports for Las Vegas use sea-level pressure, so “normal” is the same as anywhere: about 29.92 inHg (1013 hPa), with most days between 29.60 and 30.30 inHg (1002–1026 hPa). Readings above 30.20 inHg are high pressure; below 29.80 inHg is low pressure.
Why does a barometer in Las Vegas read lower than the forecast?
Las Vegas sits at about 2,001 ft (610 m). At that height the air above weighs less, so an uncorrected sensor reads around 27.82 inHg (942 hPa) on a standard day. Forecasts correct that to sea level. Set a home barometer to the sea-level value on this page, or use the station pressure line for an uncorrected comparison.
Is the pressure in Las Vegas rising or falling?
See the trend badge under the reading: it compares the latest report with the one three hours earlier. Falling pressure usually means clouds, wind or rain on the way; rising pressure means clearing and more settled weather.
