**Phoenix Sizzles as City Breaks June 30th Heat Record**

PHOENIX – Phoenix residents are sweltering under record-breaking heat today as temperatures soared to a blistering 116 degrees Fahrenheit at Phoenix Sky Harbor International Airport. The National Weather Service confirmed the record, marking June 30, 2025, as the hottest June 30th ever recorded in the city, surpassing the previous high of 115 degrees set in 2013.

The peak temperature, reached around 3 p.m., comes amidst an ongoing extreme heat wave gripping metro Phoenix. While today’s heat is significant, it’s not the hottest day of the year. June 19th saw temperatures reach a scorching 117 degrees.

The extreme heat has prompted the National Weather Service to issue an extreme heat warning for the Valley, activating on Sunday. Several Phoenix hiking trails are restricted from 8 a.m. to 5 p.m., and on Sunday, a family of 11 hikers had to be rescued from South Mountain after suffering heat exhaustion.

“We urge residents to take precautions during this extreme heat,” said a spokesperson for the National Weather Service. “Stay hydrated, limit outdoor activities, and check on vulnerable individuals.”

The extreme heat warning is currently set to expire Tuesday evening, but forecasters predict the heat will return by the end of the week, with temperatures expected to climb back above 110 degrees. The forecast also indicates the possibility of monsoon storm activity following the expected high temperatures.
