The exceptional heat wave in California brought record temperatures of 42°C in March, equaling the historic US high on the North Shore. Cities like Thermal and Palm Springs exceed the expected 43°C, while Las Vegas and Phoenix break winter records. The thermal anomaly persists in the American Southwest with values 20-30°C above normal.

L’unseasonal heat wave is overwhelming the California southern and the Southwestern United Stateswith temperatures from midsummer to mid-March. After the North Shore reached 108°F (42.2°C) on Wednesday, tying the national March record set in 1954 in Rio Grande City, Texas, meteorologists are warning that the phenomenon will continue into the weekend.

At Thermal, known for its apt name, temperatures have touched the extreme limits, with forecasts of 110°F (43.3°C) for Friday that could break the record set in March. Ruben Pantaleon, while cleaning car windshields at the intersection with a windshield wiper, downplayed the discomfort: he wore shorts and kept drinks rich in electrolytes handy. This thermal anomaly in California highlights how theexceptional heat wave is turning winter into early summer in American Southwest.

Records broken in Las Vegas and Los Angeles

Several cities experienced their warmest March day in four decades on Wednesday, according to the National Weather Service. vegas recorded 99°F (37.2°C), demolishing the previous record of 93°F from 2022. Downtown Los Angelesthermometers read 94°F (34.4°C), surpassing 1997’s 87°F for March 18.

Phoenix and the early arrival of triple digits

In Arizona, Phoenix hit 101°F (38.3°C) on Wednesday, the earliest episode of triple-digit temperatures on record, breaking the record set on March 26, 1988. Hiking trails around the city were closed due to the risk of heat exhaustion. The last time Phoenix had seen values above 37.8°C in March almost 40 years ago, underlining the extraordinary nature of this South-West heat wave.

This early summer California is hitting with extreme thermal anomalies, pushing residents into precautionary measures against the heat.

Widespread effects in the American Southwest

L’record heat wave has spawned dozens of simultaneous firsts, with subtropical air dominating the region. TO Palm Springs and surrounding areas, peaks close to 42°C evoke summer scenarios, while the extreme heat Arizona and Nevada amplifies health risks.
