Phoenix’s historic heat wave of 110-degree-plus weather shows signs of end

A historic heat wave continues to stifle Phoenix — but the end may finally be in sight for residents of Arizona’s largest city. The National Weather Service is forecasting a high of 107 degrees Fahrenheit on Monday and 102 F on Tuesday. Phoenix experienced the hottest three months since record-keeping began in 1895, including the hottest July and the second-hottest August. The daily average temperature of 97 F (36.1 C) in June, July and August passed the previous record of 96.7 F (35.9 C) set three years ago. The average daily temperature was 102.7 F in July, National Weather Service meteorologist Matt Salerno said, and the daily average in August was 98.8 F. In July, Phoenix also set a record with a 31-day streak of highs at or above 110 F (43.3 C). The previous record of 18 straight days was set in 1974. The sweltering summer of 2023 has seen a historic heat wave stretching from Texas across New Mexico and Arizona and into California’s desert.
