PHOENIX — After a brutal record-setting July, extreme heat is back in the forecast this first week of August.
As of Thursday, Phoenix has had 36 days this summer at 110 degrees or hotter. That's the second most ever recorded. The record is 53 days set in 2020 and we will definitely make a run at that record this year as high heat continues through August.
We've also had 21 days so far with lows in the 90s. That is already the second most ever recorded and we still have all of August to get through! The record is 28 days set in 2020 and that record will likely get broken this summer.
We'll also be adding to the tally of days at 115 degrees or hotter. 2023 is already in the top spot with 17 days so far. The previous record of 14 days was set in 2020.
An Excessive Heat Warning is now in effect from 10 a.m. Friday to 8 p.m. Monday as temperatures approach 115 degrees again.
Friday, Saturday, Sunday and Monday will be ABC15 Weather Action Days as a reminder to take action to protect yourself, your family and your pets from the extreme heat.
Heat is the number one weather-related killer. So, limit your time outside during the hottest part of the day and stay hydrated. Keep an eye on kids and the elderly as they can be the most affected by this heat. Bring your pets inside, too.
High pressure will be bringing the heat, but it will also cut off our monsoon moisture.
The Valley won't see any rain or thunderstorm chances for at least the next several days.
Phoenix is currently in the middle of the fourth longest dry streak on record. It has been 134 days since we've had measurable rain at Sky Harbor.
This is the first time in recorded history that Phoenix has not received any measurable rainfall in the months of April, May, June and July.
We did get a trace of rain in Phoenix early Wednesday morning, though. To date, 2023 is tied with 1995 and 1993 for the driest starts to the monsoon on record here.
In 1993, Phoenix didn't get measurable rain until August 6th. 1995 was the latest first measurable rainfall on record. That year, it didn't come until August 14th.
