Overview

• Phoenix soared to 118°F at Sky Harbor International Airport on August 7, surpassing the previous daily record of 117°F and marking the city’s hottest August day since record-keeping began.
• The first five days of August rank as Phoenix’s fourth-hottest start to the month on record, with average highs exceeding 113°F under the persistent heat dome.
• Rain prospects remain below 10% through the weekend as the high-pressure system blocks monsoon moisture, making any meaningful cooling unlikely.
• The Climate Prediction Center forecasts a 40% chance of above-normal temperatures for the rest of August, raising the possibility that this could become the hottest August on record.
• The CDC reports that extreme heat contributes to over 700 deaths annually in the U.S., prompting advisories for residents to limit outdoor activity and check on vulnerable populations.
