As the Arizona heat season nears its end, with cooler temperatures this weekend, letās take a look at the number of days over 100°F in 2026 so far.
This year, weāve had 129 days over 100°F, 39 of those days being over 110°F. Arizona also saw an unusually early start to extreme heat, breaking a record with temperatures reaching 100°F on March 18 - we normally donāt hit 100°F until May!
As climate change continues to intensify, we will continue to see an increase in heat. Each year, it becomes even more important to be aware, educated, and resilient.
Stay up to date on how the City of Tempe is working to mitigate and adapt to extreme heat in our community at tempe.gov/Sustainability.
It will be a tale of 2 seasons this week āļø š š§ļø as abnormally hot and dry conditions lead way to a cooler and wetter pattern later this weekend.
-A strong ridge of high pressure will push high temperatures well above normal through the rest of this week with most lower desert communities experiencing triple digit highs
-A much cooler and wetter weather pattern looks to take shape by this weekend into early next week with rain chances returning to much of the Desert Southwest Sunday into Monday
Stay tuned for updates!
