Las Vegas is heating up in a hurry on Tuesday, July 28, with clear skies and temperatures already climbing toward a high near 111°F this afternoon. Heat-index readings are expected to land in the low-to-mid 100s, and many valley neighborhoods will only cool into the upper 80s overnight. Anyone planning to be outside is better off pushing hard work or workouts to early morning or evening and keeping water within arm’s reach.
Extreme Heat Warning Starts Thursday
The National Weather Service has an Extreme Heat Warning in place for the Las Vegas Valley from Thursday, July 30, through Sunday, August 2, calling for dangerously hot conditions and very little overnight relief. According to NWS Las Vegas, a strong ridge of high pressure will hold daytime temperatures well above normal and create a major to extreme heat risk across the Mojave Desert. Officials advise staying in air-conditioned spaces, drinking plenty of fluids, and checking on vulnerable neighbors during the warning period.
What The Week Looks Like
Today and Wednesday are forecast to top out near 111°F, then temperatures climb even higher later in the week: about 112°F Thursday, roughly 115°F Friday, and a peak near 118°F on Saturday before easing a bit on Sunday. Nighttime lows will stay warm, mostly in the mid-to-upper 80s, so there will be limited relief after sunset. Several daily records are in play over the coming days, and forecasters say this could be among the hottest stretches of the summer.
Cooling Stations And Local Response
Clark County and local partners have opened daytime cooling stations at libraries, community centers, and select recreation sites so people without reliable air conditioning have a place to cool off. For an up-to-date list of open cooling locations and hours, check Clark County. County and health officials are urging older adults, people with chronic illnesses, and anyone without dependable A/C to use those resources during peak heat.
Afternoon Gusts And Outdoor Work
South-southwest winds will generally be light to moderate (around 3–12 mph) with afternoon gusts up to about 20 mph at times, which can make shaded but poorly ventilated spots feel especially stifling. Outdoor workers and event planners should build in frequent rest breaks in shaded or air-conditioned areas and keep crews hydrated. Never leave children or pets unattended in parked cars; interiors can reach lethal temperatures in just minutes.
Stay Safe This Heat
Drink plenty of water, skip alcohol during the hottest part of the day, wear loose light-colored clothing, and keep strenuous activity confined to early morning or evening hours. Employers should follow heat-safety practices and provide shaded or cooled rest breaks. Heat stroke is a medical emergency, so call 911 if someone becomes confused, faints, or is unresponsive. Check on neighbors and pets, and have a backup plan ready in case power or A/C fails.
