Phoenix set a new daily temperature record Aug. 6, reaching a sizzling 116 degrees as dangerous heat continues to blanket the Valley.

The new record was set at 4:21 p.m. at Sky Harbor International Airport, surpassing the previous record of 114 degrees previously hit in 2023, 2018 and 1995. And it’s not cooling down anytime soon with higher temperatures in the forecast.

“We’re looking at unusually hot temperatures this week across the Phoenix metro,” said Mark O’Malley, a meteorologist for the National Weather Service in Phoenix. “Thursday we’ll probably flirt with or break the record high for the date.”

The forecast high on Thursday, Aug. 7, is 117 degrees, and the standing record for that day is 112 degrees. Temperatures hovering around 110 are expected to continue through early next week.

An unusually intense high-pressure system has settled over central Arizona, fueling the latest round of triple-digit highs and keeping any meaningful rain out of reach.

Rain chances remain low across the metro, with less than 10% chances through the weekend, though isolated mountain storms may occur.

Overnight lows won’t provide much relief, as temperatures are expected to stay in the mid-80s to the low 90s, which can be dangerous when people don’t have time to cool down.

“We want people to use caution,” O’Malley said. “Don’t do strenuous activity outdoors, and if you must be outside, take as many breaks in air conditioning as possible.”

How to stay cool in extreme heat

  • Stay hydrated: Drink plenty of water throughout the day, even if you don’t feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate you
  • Limit outdoor activity: Try to stay indoors during peak heat hours, usually between 10 a.m. and 6 p.m. 
  • Use sun protection: Wear lightweight, loose-fitting clothing, a wide-brimmed hat and sunscreen with at least SPF 30 
  • Check on vulnerable people: Keep an eye on the elderly, children and pets who are especially sensitive to the heat 
  • Know the signs of heat illness: Dizziness, headache, nausea, rapid heartbeat and confusion can signal heat exhaustion or heat stroke. Seek medical help immediately
