Phoenix Arizona Hit 110 Degres For 50 Days Straight

As if we didn’t already know how sweltering Arizona can be, it just got official. Friday, August 28 was the 50th straight day of at least 110-degree temperatures, and a heatwave quite like this has never been seen before in the Grand Canyon State.

As of Friday, August 28, the Valley reached at least 110 degrees for 50 consecutive days. The previous record of 33 days was set back in 2011.

August 9 was the day Phoenix officially surpassed the nearly decade-old record. On Friday afternoon, the 50th day, it was 111 degrees at Phoenix Sky Harbor International Airport. What a scorcher!

Unrelenting high pressure is to blame for the heatwave. High pressure leads to warmer-than-average temperatures, which were made even worse by an unusually dry summer.

Phoenix normally relies on monsoons to cool things down, but they’ve been few-and-far-between. The city has received under four inches of rainfall since 2020 began.

Luckily, thunderstorms over the weekend provided some relief. It was 77 degrees in the late evening of August 30!

Experts say the concrete and asphalt in urban areas like Phoenix soak up heat from the sun. This is referred to as the “heat-island” effect, which exists to a much lesser degree in undeveloped regions.

According to the National Weather Service, Phoenix is, on average, three degrees hotter during the summer months than it was in the 1970s. Can you feel the difference?
