Arizona Desert Town Shatters US March Heat Record Amid Scorching Heatwave
A small community in the Arizona desert has broken the record for the highest March temperature ever recorded in the United States, as the Southwest endures a blistering late-winter heatwave. The astonishing temperature was recorded just outside Martinez Lake, Arizona, which reached 110°F (43.3°C) on Thursday, according to the National Weather Service (NWS). This surpasses the previous record of 108°F (42.2°C) set in Rio Grande City, Texas, in 1954, which was tied on Wednesday by North Shore, California.
Record-Breaking Heat Across the Southwest
The community of Martinez Lake is located about 145 miles west of Phoenix and sits on the Arizona-California border in the Yuma desert. By Thursday, several more California locations had hit 108°F, including Cathedral City near Palm Springs and the town of Thermal northeast of San Diego. Thermal was forecast to hit 110°F on Friday, potentially tying the new record. The NWS noted that these triple-digit temperatures came on the last day of winter, with the average first 105°F day normally occurring on May 22nd.
This blistering wave of heat has established record highs in dozens of locations across the region. Phoenix reached 105°F, surpassing its previous record of 102°F set on Wednesday, marking the earliest day of triple-digit temperatures in the city in nearly 40 years. As a result, hiking trails around Phoenix were closed on Thursday due to the risk of heat illness. Las Vegas also hit 95°F, topping its previous record of 94°F set on Wednesday.
Climate Crisis Link and Local Impacts
A team of scientists has determined that this week's scorching weather would have been "virtually impossible" without the climate crisis. An analysis released on Friday found that global heating has made the type of heatwave seen this week four times more likely over the past decade. The NWS stated that temperatures will continue to be 20 to 30 degrees Fahrenheit above normal for March in the Southwest for the rest of the week before dropping slightly on Sunday, with many cities expected to see their earliest 100-plus °F day on record.
Despite the extreme conditions, some residents remain unfazed. Ruben Pantaleon, who was cleaning car windshields at an intersection in Thermal on Thursday afternoon, said the heat did not bother him, noting he wore shorts and had electrolyte drinks on hand. "It's the desert. It gets real hot. I'm not worried about it," he said under the blaring sun.
