PHOENIX — Temperatures are heating up once again across Arizona!

High pressure building in will send highs Sunday in Phoenix back near the upper 80s. Fortunately we will still have a pleasant morning with lows in the 60s.

As the high-pressure system continues building in, it will push temperatures into the low 90s by Tuesday, Wednesday, and Thursday of next week.

Typically, Phoenix’s last 90-degree day falls around October 30th, though we've seen 90s as late as mid-November, like in 2020.

A slight drop in temperatures is in store just in time for Halloween. It looks like highs will be in the mid to upper 80s, with trick-or-treating temps in the 70s.
