The string of hot weather follows what has been a cooler than usual month for the Valley, driven by a wet monsoon season.

Temperatures in the Valley have surpassed the normal high only eight times so far in August, as opposed to 15 days below average, according to the National Weather Service.

Five days with temperatures at least 10 degrees below normal were also recorded.

Phoenix through Aug. 21 has had 17 days of measurable rainfall, the second-most during that time span, according to the National Weather Service.

When accounting for the entire monsoon, which comes to a close on Sept. 30, the days of measurable rainfall so far this season is tied for 14th-best.

It has been a welcome sight for Valley residents this summer after last year when August was the hottest month ever recorded in Phoenix history, as the average temperature over the course of the month was 99.1 degrees.
