Record-Breaking Heatwave Scorches US Southwest as Phoenix Shatters Temperature Records
Phoenix Hits 47.2°C in Record Southwest Heatwave

The US Southwest is currently gripped by an unprecedented and dangerous heatwave, with Phoenix, Arizona, at the epicentre of the scorching conditions. The National Weather Service (NWS) has issued urgent warnings as temperatures skyrocket to alarming levels.

On Tuesday, Phoenix Sky Harbour International Airport recorded a staggering high of 47.2°C (117°F), shattering previous records and inching dangerously close to the city's all-time record of 50°C (122°F) set in 1990.

"An Oppressive and Dangerous Situation"

Meteorologists from the NWS have characterised the weather event as exceptionally severe. The service's Phoenix office emphasised the critical nature of the event, stating, "The predominant weather concern will be the increasingly hot temperatures... An Excessive Heat Warning is in effect for much of south-central Arizona through the upcoming weekend."

They further warned that this level of heat poses a major risk to public health, particularly for those without access to effective cooling or adequate hydration.

Health Experts Sound the Alarm

Medical professionals and health experts are urging extreme caution. The primary advice is to prioritise staying indoors in air-conditioned spaces during the peak afternoon hours. For those who must venture outside, recommendations include:

  • Drinking significantly more water than usual.
  • Wearing lightweight, light-coloured, and loose-fitting clothing.
  • Applying high-SPF sunscreen regularly.
  • Never leaving children or pets unattended in vehicles, where interior temperatures can become lethal within minutes.

The risks of heat exhaustion and the more severe heatstroke are significantly elevated during such extreme weather events.

A Broader Regional Crisis

The blistering heat is not confined to Phoenix. A vast swathe of the Southwest, including much of California, southern Nevada, and parts of Texas, is under similar heat advisories and excessive heat warnings. This widespread event is testing power grids and straining infrastructure across the region.

This intense heatwave serves as a stark reminder of the increasing frequency and intensity of extreme weather events, with experts linking such patterns to broader global climate trends. Residents are advised to stay informed through official NWS channels and to check on vulnerable neighbours, especially the elderly.
