Scorching history: Las Vegas hits 120°F for the first time on record

A scorching milestone in the city’s climate history
On July 7, 2024, Las Vegas recorded an astonishing 120°F at Harry Reid International Airport, shattering the previous all-time high of 117°F—a mark that had stood since 1942. This record-setting temperature was confirmed by the National Weather Service as part of the region’s most intense summer heat wave on record.
The city had never officially reached 120°F before, and that same day saw the day’s high climb rapidly—from 118° at 2:33 p.m. to 119° at 3:13 p.m., before peaking at 120° at 3:38 p.m. Las Vegas also experienced five consecutive days at or above 115°F, a streak unusual even for desert summers.
That July marked the hottest month ever recorded in Las Vegas. Average daytime highs soared to around 111.5°F, with nighttime lows staying above 88°F—far beyond typical July averages.
How this compares to typical summers
Las Vegas summers are known for intense heat, with average highs in July nearing 104.5°F. About 78 days a year climb past 100°F, and more than 10 exceed 110°F. What made July 2024 exceptional was not just the peak temperature but its duration—breaking records with sustained triple-digit readings nearly every day.
Looking ahead to this week
As of now, Las Vegas isn’t expected to approach 120°F during the upcoming weekend, but dangerously hot conditions persist. Expect highs in the upper 100s to low 110s through Sunday. With today’s forecast reaching up to 112°F and little relief overnight, residents should remain vigilant.
Health and safety tips
- Stay hydrated, and carry water whenever outdoors.
- Avoid peak sun—limit outdoor activities between 11 a.m. and 4 p.m.
- Check on vulnerable neighbors—young children, elderly residents, and pets are especially at risk.
Keep pets indoors during the hottest parts of the day and avoid asphalt where the ground heats up quickly.
