Las Vegas woke up already baking in the low 90s this morning (Friday, July 24, 2026) under clear skies, and the heat is not tapping out anytime soon. High temperatures are expected to surge into the low 110s, roughly 111–113°F, through the weekend, while overnight lows stubbornly linger in the low 90s. With the heat index making it feel even hotter, anyone working or exercising outside faces a higher risk of heat-related problems.
What The Forecast Means
The National Weather Service has issued an Extreme Heat Warning in effect through 8 p.m. on Monday, July 27, 2026, for the Las Vegas valley and surrounding desert areas. Forecasters are calling for valley highs of 108–114°F with limited overnight relief, a combination that significantly raises the odds of heat-related illness for vulnerable residents. The advice is basic but serious: avoid strenuous activity in the middle of the day, carry water, and check in on neighbors and anyone without reliable air conditioning. For the full rundown of what to expect, see the advisory from the National Weather Service.
Afternoon Thunderstorms Possible
Monsoonal moisture will keep the door open for isolated showers and thunderstorms mainly between about noon and 5 p.m., with roughly a 20% chance across the valley. Any storm that pops up could unleash sudden gusty outflow winds, brief heavy rain, and localized flash flooding, especially over higher terrain and recent burn scars. Coverage will be spotty, so most areas will see brief, localized impacts rather than a widespread soaking.
Where To Cool Off
Clark County has activated daytime cooling stations at libraries, recreation centers, and community centers across the valley, offering some much-needed relief from the heat. A full list of locations and hours is available on the county website. If you do not have reliable air conditioning, call 311 or check the county page for the nearest cooling site and its operating hours. Many library branches are serving as daytime respite locations, according to Clark County.
Who’s Most At Risk And Safety Tips
Older adults, infants, people with chronic medical conditions, outdoor workers, and unhoused residents are at the highest risk during a multi-day heat event like this one. Avoid strenuous activity during the hottest hours of the day, roughly 2–6 p.m., and drink water frequently even if you do not feel thirsty. Lightweight, light-colored clothing helps your body cope a bit better, and children or pets should never be left in parked vehicles, even for a short time.
Heat stroke is a medical emergency. If someone becomes confused, collapses, has a very high body temperature, or develops hot, dry skin, call 911 immediately.
