News Summary
Phoenix has set a new record for the highest daily low temperature at 92 degrees, surpassing the previous record of 90 degrees. This extreme heat is compounded by limited rainfall, as the Valley faces ongoing heat warnings and potential storms. With minimal rainfall recorded this year, residents are urged to remain cautious and updated on the weather. The National Weather Service indicates a chance of rain and predicted cooler temperatures in the coming days, but concerns persist about the impacts of the prolonged heat on the community.
Phoenix experienced an unprecedented record high daily low temperature of 92 degrees on Saturday, August 23, 2025, overshadowing the previous record of 90 degrees set in 1998. This temperature spike adds to a prolonged period of extreme heat, as a Valley heat warning has been extended through Sunday at 8 p.m. The typical low for this date is generally around 83 degrees.
On the same day, the unofficial high temperature reached 109 degrees at 3:58 p.m., which is four degrees above the average for this time of year. However, it remains five degrees below the daily record high of 114 degrees, recorded in 2011. Many residents are facing the ongoing impacts of the extreme conditions, exacerbated by limited rainfall this monsoon season.
So far in 2025, Phoenix has recorded only 0.2 inches of rainfall, significantly lower than the usual 1.5 inches expected by late August. On August 22, a brief storm brought a modest 0.04 inches of precipitation at Phoenix Sky Harbor International Airport, breaking a prolonged dry spell. However, the cumulative total for the monsoon season remains well below the average of 1.57 inches.
The National Weather Service (NWS) has indicated a 25% chance of rain throughout the weekend, yet the forecast suggests that not all areas in the Valley will experience precipitation. Anticipated cooler temperatures are expected to return early next week, with weather dropping to around 100 degrees on Tuesday and Wednesday. However, overnight lows are likely to remain elevated, continuing a trend of lower 90s.
As a result of storms on August 22, strong winds peaking at 60 mph led to damage in parts of the Valley, including downed trees and power outages. Approximately 19,500 SRP customers were affected, though most had their power restored by the morning of August 22. Additionally, Monday and Tuesday are designated as First Alert days due to potential storm activity, particularly during Monday evening. Meteorologist Alex Young from the NWS has warned that these storms could cause disruptions, particularly for commuters.
The recent extreme temperatures and minimal rainfall are becoming concerning for residents of Phoenix and surrounding areas. Residents are urged to stay updated on weather forecasts and take precautions due to the ongoing heat warning and potential storms. While there is hope for cooling temperatures and rain in the near future, it remains to be seen how widespread and impactful these weather systems will be.
