Forecasts indicate that the United States might soon match its highest temperature recorded on Earth. A potentially significant heat event is predicted for California’s Death Valley this weekend. Some forecasts suggest temperatures might reach 129 degrees Fahrenheit on Sunday, close to the highest reliable temperature recorded, which was 130 degrees at Furnace Creek in July 2021.
The National Weather Service (NWS) Las Vegas forecasters indicate that the region could witness “dangerous and potentially record-breaking temperatures” from Thursday to early next week. However, forecasting temperatures days in advance includes a margin of error, meaning the actual temperature could be slightly off.
The NWS Weather Prediction Center predicts temperatures that could shatter records across the Southwest, such as 117 degrees in Las Vegas on Saturday. While Death Valley isn’t detailed on the forecast webpage, meteorologist Marc Chenard notes the potential for daily temperature records to break this weekend. Current forecasts predict highs of 123 on Saturday and 124 on Sunday for Death Valley. Extreme weather chaser Colin McCarthy mentions that Death Valley might hit 130°F (54.4°C), echoing thoughts shared by WFLA-TV chief meteorologist Jeff Berardelli.
Hurricane Genevieve’s Indirect Impact
The heat may intensify due to Hurricane Genevieve, a Category 3 storm, swirling in the Eastern Pacific. Though it won’t make landfall, it could affect temperatures indirectly. As it moves past a strong heat dome over the Southwest, its outflow might boost the upper-level ridge, causing temperatures to jump, as Berardelli explains.
Death Valley’s Hot Temperature History
Death Valley recorded a controversial temperature of 134 degrees Fahrenheit in 1913. However, Colin McCarthy argues that the measurement is likely erroneous. A study from 2026 deemed the reading “physically implausible,” suggesting it was overestimated by 12-16°F.
Experts now consider the highest reliable temperature as 130.0 °F (54.4°C) recorded at Furnace Creek Visitor Center on July 9, 2021. Still, the World Meteorological Organization continues to list the 1913 record as official.
The NWS Las Vegas office has issued an Extreme Heat Warning for much of southern Nevada, southeastern California, and northwestern Arizona from Thursday morning to Sunday evening. Forecasters predict highs between 110 to 120 across the Mojave Desert, with Death Valley remaining one of the hottest locations. Evening temperatures will stay warm, with lows possibly reaching 95 degrees, offering little overnight relief.
Staying Safe in Extreme Heat
Health officials highlight the potential dangers of extreme heat, especially for older adults, children, outdoor workers, and those with chronic health issues. The NWS advises staying hydrated, seeking air-conditioned environments, and avoiding sun exposure during peak temperatures. Checking on vulnerable people is crucial.
The NWS warns against caffeine and alcohol consumption during extreme heat events. Those outdoors should wear light, loose clothing and limit activity to cooler parts of the day. Breaks in shaded or air-conditioned spots are recommended. Children and pets should never be left in parked vehicles, as temperatures can become deadly rapidly.
Recognize signs of heat exhaustion, such as heavy sweating, dizziness, and nausea. Immediate medical care is necessary if heat stroke symptoms appear. Heat stroke can lead to confusion, unconsciousness, and dangerously high body temperatures, and is a medical emergency.
As of now, attention focuses on Death Valley’s weather, as the U.S. may again tie a significant global weather record.
