Potential Record-Breaking Temperatures Loom in Death Valley

California’s Death Valley might soon match the highest temperature ever reliably recorded on Earth. Forecasters predict a severe heat event this weekend. Predictions show a potential high of 129 degrees Fahrenheit on Sunday in Death Valley’s hottest area. This temperature is close to the 130 degrees recorded at Furnace Creek in 2021, regarded as the highest reliable measurement on Earth.

The National Weather Service (NWS) office in Las Vegas warns of “dangerous and potentially record-breaking temperatures” starting Thursday. These high temperatures could persist into early next week. Predicting a forecast temperature days in advance typically involves a margin of error. This means the anticipated 129 degrees could vary slightly lower or higher.

With temperatures so near the historical high, small shifts in the forecast might determine whether Death Valley matches, ties, or exceeds this record.

The NWS Weather Prediction Center forecasts multiple record-breaking temperatures across the Southwest this weekend. For instance, Las Vegas could reach 117 degrees on Saturday. Though Death Valley isn’t listed on this forecast page, Marc Chenard from the NWS Weather Prediction Center mentioned that some daily records might break this weekend. The NWS forecast anticipates a high of 123 degrees on Saturday and 124 on Sunday in Death Valley.

Extreme weather chaser Colin McCarthy highlighted the possibility of Death Valley reaching 130°F, tying the highest temperature ever recorded reliably. Jeff Berardelli, WFLA-TV chief meteorologist, echoed this sentiment. He noted that atmospheric conditions might give the boost to hit this historical high, with a forecast suggesting 129 degrees.

Hurricane Genevieve and Its Potential Impact

Hurricane Genevieve, a Category 3 storm, could indirectly influence the extreme heat. As it moves in the Eastern Pacific, it’s not expected to make landfall. However, its outflow might bolster the upper-level ridge over the Southwest, raising temperatures further.

Contesting the 1913 Temperature Record

Death Valley’s 1913 record of 134 degrees Fahrenheit has long been contested. According to McCarthy, this reading is probably inaccurate. A study in 2026 suggested the temperature might have been 12-16°F too high. The most reliable recorded temperature, accepted by climatologists, is 130.0°F recorded on July 9, 2021, at Furnace Creek Visitor Center.

Despite this, the World Meteorological Organization still lists the 1913 record as official.

The NWS Las Vegas office has issued an Extreme Heat Warning covering parts of southern Nevada, southeastern California, and northwestern Arizona, from Thursday morning through Sunday evening. Dangerous highs, ranging from 110 to 120 degrees, are predicted across the Mojave Desert, with Death Valley being among the hottest areas. Some locations might experience overnight lows of 95 degrees, providing negligible relief after sunset.

Death Valley, known as one of the hottest places on Earth, often sees summer temperatures surpass 120 degrees. Its below-sea-level position and surrounding mountains trap heat, allowing the desert floor to reach extraordinary temperatures.

Extreme Heat Precautionary Measures

Health officials emphasize the dangers of extreme heat, especially for older adults, children, outdoor workers, and those with chronic conditions. The NWS advises drinking plenty of fluids and staying in air-conditioned settings whenever possible. Avoiding direct sunlight during peak heat hours is also critical.

Residents should check on vulnerable individuals. Avoid caffeine and alcohol during such events, as they increase dehydration risk. Lightweight, loose clothing is recommended, and any outdoor activities should be scheduled for early morning or evening. Regular breaks in cooler environments are crucial.

Avoid leaving children or pets in parked cars. Vehicle interiors can reach deadly temperatures in minutes during extreme heat.

Watch for signs of heat exhaustion, such as heavy sweating, dizziness, and nausea. Immediate medical help is necessary if symptoms of heat stroke occur, like confusion or loss of consciousness.

Current forecasts focus on Death Valley’s temperatures over the upcoming weekend. If predictions hold, the U.S. might once again match one of Earth’s most extreme weather records.
