Hot summer day in downtown Phoenix: Sights and sounds as people cope
With an extreme heat warning in effect and temperatures near 110 on July 31, 2025, the sun bakes pedestrians as they walk in downtown Phoenix.
Another day, another heat record in Phoenix, as America’s hottest city sweltered through its warmest August day in over 120 years of record-keeping.
The temperature soared to 118 degrees at Phoenix Sky Harbor International Airport at 3:40 p.m. on Aug. 7. The previous record for the hottest August day was 117 degrees, reached most recently in 2023.
The daily record high of 112 degrees was broken before lunchtime as the heat continued to build through the afternoon.
“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. “There’s a strong area of high pressure which has settled directly over central Arizona.”
The weather service has issued extreme heat warnings across much of the region, as the system keeps relief from monsoon showers limited to southeastern Arizona and Mexico.
What was the temperature in Phoenix yesterday?
The high temperature of 118 degrees broke the record for the hottest day in August. The previous record was 117 degrees.
The normal temperature for Aug. 7 is 105 degrees.
The old daily record for Aug. 7 of 112 degrees was broken at 11:30 a.m.
What’s the weather forecast?
Temperatures will be slightly lower for Friday, Aug. 8, with a high expected around 112 degrees. The overnight low will remain warm, with a forecast of 88 degrees.
There is a 10 percent chance of rain overnight and again Saturday night.
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.
