Las Vegas baked Wednesday in its record fifth consecutive day of temperatures sizzling at 115 degrees Fahrenheit (46.1 Celsius) or greater amid a lengthening hot spell that is expected to broil much of the U.S. into the weekend, the National Weather Service said.
The temperature climbed to 115 shortly after 1:00 p.m. at Harry Reid International Airport, breaking the old mark of four consecutive days set in July 2005. On Sunday, the heat wave set Las Vegas’ all-time temperature record of 120 F (48.8 C).
Even by desert standards, the prolonged baking that Nevada’s largest city is experiencing is nearly unprecedented.
“This is the most extreme heat wave in the history of record-keeping in Las Vegas since 1937,” said meteorologist John Adair at the National Weather Service office in southern Nevada.
Keith Bailey and Lee Doss met early Wednesday morning at Las Vegas park to beat the heat and exercise their dogs, Breakie, Ollie and Stanley.
“If I don’t get out by 8:30 in the morning, then it’s not going to happen that day,” Bailey said, wearing a sunhat while the dogs played in the grass.
Alyse Sobosan said this July has been the hottest in the 15 years she has lived in Las Vegas. She said she doesn’t step outside during the day if she can help it, and she waits until 9 p.m. or later to walk her dogs.
“It’s oppressively hot,” she said. “It’s like you can’t really live your life.”
It’s also dangerously hot, health officials have emphasized. There have been at least nine heat-related deaths this year in Clark County, which encompasses Las Vegas, according to the county coroner’s office. Officials say the toll is likely higher.
“Even people of average age who are seemingly healthy can suffer heat illness when it’s so hot it’s hard for your body to cool down,” said Alexis Brignola, an epidemiologist at the Southern Nevada Health District.
For homeless residents and others without access to safe environments, officials have set up emergency cooling centers at community centers across southern Nevada.

More than 142 million people around the U.S. were under heat alerts Wednesday, especially in Western states, where dozens of locations tied or broke heat records over the weekend and are expected to keep doing so all week.
Oregon has seen record daily high temperatures, with Portland reaching 103 F (39.4 C) and Salem and Eugene hitting 105 F (40.5 C) on Tuesday. The high temperatures are suspected to have caused eight deaths, the state medical examiner’s office said. The youngest was 33, but all of the others were age 64 and older.
On the other side of the nation, the National Weather Service warned of major-to-extreme heat risk over portions of the East Coast.
An excessive heat warning remained in place Wednesday for the Philadelphia area, northern Delaware and nearly all of New Jersey. Temperatures were around 90 F (32.2 C) for most of the region, and forecasters warned the heat index could soar as high as 108 F (42.2 C). The warning was due to expire at 8 p.m. Wednesday, though forecasters said there may be a need to extend it.
The heat was blamed for a motorcyclist’s death over the weekend in Death Valley National Park. At Death Valley on Tuesday, tourists queued for photos in front of a giant thermometer that was reading 120 F (48.9 C).
Simon Pell and Lisa Gregory from London left their air-conditioned RV to experience a midday blast of heat that would be unthinkable back home.
“I wanted to experience what it would feel like,” Pell said. “It’s an incredible experience.”

The U.S. heat wave came as the global temperature in June was a record warm for the 13th straight month and marked the 12th straight month that the world was 1.5 degrees Celsius (2.7 degrees Fahrenheit) warmer than pre-industrial times, the European climate service Copernicus said. Most of this heat, trapped by human-caused climate change, is from long-term warming from greenhouse gases emitted by the burning of coal, oil and natural gas, scientists say.
Firefighters in Henderson, Nevada, last week became the first in the region to deploy what city spokesperson Madeleine Skains called “ polar pods, ” devices filled with water and ice to cool a person exhibiting symptoms of heat stroke or a related medical emergency.
