PHOENIX — We are in the thick of the hottest days of 2021 in Arizona so far!

It was a slow start to the extreme heat so far compared to last year's record-setting summer, but now temperatures are skyrocketing.

WHAT'S HAPPENING

High pressure has moved in and is parking itself over Arizona, sending temperatures soaring.

We are now tracking our first week with temperatures at 110 degrees or more. In fact, temperatures could go as high as 117 degrees in Phoenix.

Excessive Heat Warnings are now in effect across central, southern and western Arizona through Sunday.

Excessive Heat Warnings also extend across the lower elevations of northern Arizona through the end of the week.

RECORD HIGHS IN JEOPARDY

Not only will this week be unseasonably hot, but records will likely be set in Phoenix and several locations across Arizona.

WHAT TO WATCH FOR

Sunburn, dehydration, and heat-related illnesses can impact the human body in a matter of minutes!

So, we will be in ABC15 Weather Action Mode. That means you need to take action to keep yourself and your family safe.

Heat is the number one weather-related killer. Last year, we lost more than 300 people to heat-related deaths in the Valley.

So, be sure to take action by staying hydrated and avoiding outdoor activities during the hottest time of the day.

HISTORICAL LOOK

On average, our first day at 110º or hotter happens around June 11th.

With the latest climate averages from 1991 to 2020, the number of 110-degree days each year has increased.

Phoenix now averages 21 days a year at 110 degrees or more. That's up from the previous 30-year average of 19 days a year and from the all-time average of 12 days a year.
