What is the hottest day ever recorded in Las Vegas?

Las Vegas's hottest day on record reached 120°F, set on July 7, 2024.

What is the record high temperature in Las Vegas?

The all-time record high in Las Vegas is 120°F, recorded on July 7, 2024. Records are drawn from the nearest long-term weather station's full daily history, so this is the hottest single day the station has ever logged — not a typical summer peak.

What is the coldest day ever recorded in Las Vegas?

Las Vegas's coldest day on record bottomed out at 8°F, set on January 13, 1963. Like the record high, it comes from the station's full daily record, so it captures the most extreme cold the area has recorded rather than an average winter low.

What is the record low temperature in Las Vegas?

The all-time record low in Las Vegas is 8°F, recorded on January 13, 1963. The gap between that and the 120°F record high — a span of 112°F — is the full range of temperatures Las Vegas has experienced across its long-term daily record.

Is it normal to be this hot in Las Vegas?

It depends on how far above Las Vegas's normal a given day runs. A typical year here averages a daily high near 81°F; the all-time record of 120°F (set 2024) sits about 39°F above that. When a live reading is available, the live readout just below the record high and low compares it with the temperature typical for that hour this month (estimated from the month's normal high and low), so you can see how unusual the day is rather than guessing.

When did Las Vegas set its temperature records?

Las Vegas's record high of 120°F was set in 2024 (July 7, 2024), and its record low of 8°F in 1963 (January 13, 1963). Both are pulled from the station's full daily record going back to 1948, so they reflect the true extremes rather than a recent or partial sample.

Has Las Vegas been getting hotter?

Yes — Las Vegas's annual mean temperature has trended about 6.5°F warmer since 1949 (+0.85°F per decade, fitted to the complete years of 1949–2025). That gradual shift in the average is separate from the all-time records above, which mark the single most extreme days rather than the trend, but a warming baseline is part of why recent years more often brush up against the record-high end.

How extreme Las Vegas’s weather gets

Las Vegas’s weather is usually mild by its own standards — a typical year averages a daily high near 81°F, and the normal high for September runs about 95°F. The records sit well outside that everyday range. The hottest day on record reached 120°F in 2024 — roughly 39°F above a typical year’s average high, the kind of gap that turns an ordinary summer into a genuine heat event.

At the other end, Las Vegas has bottomed out at 8°F (1963). Those edges are why the today-versus-normal readout above is worth a glance: it shows where today falls between the normal and the record, so a hot afternoon can be judged against the real history rather than a hunch. A reading a few degrees over the September normal is ordinary; one pushing toward the 120°F record is the rare event the record marks.
