- Posted in Weather Records by

Feeling hot? You are not alone!

On August 9th, Phoenix Sky Harbor broke the 110º mark for the 34th time so far this year! This breaks the old record of 33 days, which was set in 2011. The average number of 110º+ days stands at 19.

Keep in mind, the Valley of the Sun broke this record on Aug 9th and the average last 110º+ day is not until August 26th, so still plenty of time to rack up more very hot days. In fact, looking at the current forecast, the tally this year could be at 40 days by the end of next weekend.

Stay cool!

June 26, 1990 - Hottest Day Ever in Phoenix

- Posted in Weather Facts by

If you thought the past few years have been hot, they have nothing on the year 1990!

To get a picture of the record-setting 1990 heat wave, it all started on June 20, when the high temperature in Phoenix reached 113º. The high stayed at or above 113º through June 24, until a high of 120º was measured on June 25. At the time, it was the highest temperature Phoenix had ever recorded since records began in 1896. Sadly, that record did not last long, as the very next day (June 26) the temperature topped out at a remarkable 122º! This temperature still stands as the hottest temperature ever recorded in Phoenix. This record stands just 12º cooler than the record high temperature ever recorded on Earth. That record was set on July 7, 1913, at Furnace Creek (Death Valley), at a scorching 134º.

To understand how intense this Phoenix heat was, let's take a quick look back at what those living in Phoenix would have felt on June 26, 1990.

First off, the low that morning was already 91º. By 8 am, the temperature had risen to 99º and was up to 112º by 11 am. No, that is not a typo; it was above 110º before noon! At 2 pm the temperature rose to the 120º mark and finally at 4 pm, the thermometer read the record-setting 122º! The temperature cooled to 120º by 5 pm and 119º an hour later. The heat continued through the night, with temperatures staying above 100º until midnight! Overall, the temperature remained above 100º for 15 hours, above 110º for 10 hours, and at or above 120º for 4 hours. Bottom line, it was HOT!
