Las Vegas starts Saturday, August 1, under clear skies and temperatures in the mid-80s, but the brief morning reprieve will disappear fast. The forecast calls for a sunny high near 116 degrees, with dangerous heat lingering well into the night.
An Extreme Heat Warning remains in effect through 8 p.m. Sunday, according to the National Weather Service in Las Vegas. Officials say temperatures from 110 to 120 degrees are expected across parts of the Mojave Desert, with little overnight relief and a heightened risk of heat-related illness.
Saturday’s Heat Arrives Fast
Temperatures are expected to reach about 103 degrees by 10 a.m., 108 degrees around noon and 114 degrees by midafternoon. The high is forecast near 116 degrees between 3 and 6 p.m., with southeast winds generally between 1 and 9 mph and no rain in sight.
Overnight Temperatures Stay Near 90
Saturday night will be mostly clear, but the low is expected to fall only to around 91 degrees, with heat index values as high as 106. Sunday will bring another sunny day with a high near 114 degrees, while south winds could gust to 28 mph during the afternoon.
The heat is expected to continue next week, although highs may ease slightly to 113 degrees Monday through Wednesday, 112 Thursday and 111 Friday. Overnight lows will remain unusually warm, generally between 88 and 90 degrees, while rain chances stay near zero through most of the period.
Stay Cool And Avoid The Afternoon Sun
Residents are advised to drink plenty of fluids, remain in air-conditioned spaces when possible and limit strenuous outdoor activity to the early morning or evening. Never leave children or pets in unattended vehicles, and check on relatives and neighbors who may be especially vulnerable to extreme heat.
Outdoor workers should take frequent breaks in shaded or air-conditioned areas. Anyone showing signs of heat stroke should be moved to a cool location immediately, and 911 should be called for emergency help.
