Las Vegas is locked under an Extreme Heat Warning through Monday, July 27, with dangerous daytime highs and barely any relief after dark. Forecast temperatures are expected to climb into the low to mid 110s across the valley, and overnight lows lingering near the low 90s mean the risk from heat does not let up once the sun goes down. Officials are urging residents to stay indoors when possible and to use cooled public spaces if air conditioning is not available at home.
What To Expect
Sunny, dry weather will drive Saturday’s high to about 114°F and keep daytime temperatures above 110°F through Monday, with afternoon winds gusting into the 20s mph and heat-index values near 109°F. The National Weather Service has an Extreme Heat Warning in place through 8 p.m. PDT Monday, July 27, and lists the extreme heat as a threat to health for anyone working or recreating outdoors, according to the National Weather Service.
Cooling Stations And Safety
Clark County has opened staffed cooling stations around the valley, with hours and locations that vary by site, so residents are urged to check the county list before heading out. People without reliable air conditioning are encouraged to use these centers when possible and to follow basic heat safety guidance: drink plenty of fluids, avoid heavy exertion during peak afternoon heat, and never leave children or pets unattended in vehicles, as local officials recommend. For details on specific locations, see the county list at Clark County.
Why This Matters
Forecasters say a stubborn high-pressure ridge will keep temperatures about 5 to 10°F above normal and limit overnight cooling, which can drive up heat-related emergency calls and strain cooling resources across the region. The National Weather Service forecast discussion also notes that several daily high and warm-minimum records are close enough to be threatened by the current forecast, a particular concern for people who lack air conditioning or who have to work outdoors.
Plan Ahead
If you have to be outside, shift heavy work to early morning or evening, take frequent breaks in the shade with water, and wear lightweight, loose-fitting clothing. If someone shows signs of heat stroke, such as confusion, loss of consciousness, or very hot and dry skin, call 911 immediately and move the person to a cool, shaded area while you wait for help.
