Phoenix is baking under mostly sunny skies today with a high near 109°F and heat index values climbing to 111, and an Extreme Heat Warning is posted for the area — so save Camelback Mountain, Piestewa Peak, and South Mountain Park hikes for before 8 AM MST or after 7 PM MST, and skip strenuous outdoor plans in between.
Today’s Setup
Overnight lows only dropped to around 90°F before rising again, and today’s west wind stays light at 0 to 10 mph, so there’s no relief from moving air. A leftover disturbance brought a slight chance of showers and storms before 5 AM, but that’s clearing, and forecasters expect mostly sunny skies the rest of the day.
Best Window To Be Outside
Early morning, roughly sunrise to 8 AM, is your best bet for the Grand Canal paths or a jog around Tempe Town Lake before temperatures climb into the triple digits. After sunset, once temps ease toward the low 90s, patios around Roosevelt Row and CityScape open back up.
Heat & Monsoon Risk
The National Weather Service Phoenix office says above-normal heat continues through midweek, with Wednesday’s high near 110°F and heat index up to 112 — another Extreme Heat Warning day. Monsoon moisture is in place, but forecasters note thunderstorm chances favor the high terrain of northern and southeast Arizona; Phoenix’s low desert only carries an 11% storm chance today and just 3% Wednesday. Later this week, high pressure is expected to strengthen further, bringing another round of Major to Extreme Heat Risk.
What To Wear Or Bring
Lightweight, light-colored clothing and SPF 50 sunscreen are non-negotiable, and men’s sport sandals beat closed shoes for keeping feet cool on errands. Pack an insulated tumbler 30oz to keep water cold through the afternoon, and if the kids need backyard relief, a kids sprinkler toy does the trick. Heading out tonight to Arizona Financial Theatre for Lindsey Stirling or The Van Buren for Flyleaf with Lacey Sturm? Both shows are July 28 — Get tickets on SeatGeek before doors, and remember these are indoor venues, so the heat only hits you on the walk from the parking lot.
Games, Concerts & What’s Next
Grupo Frontera brings the Triste Pero Bien C*bron Tour to Mortgage Matchup Center on Friday, July 31 — Find tickets on StubHub and grab a Grupo Frontera t-shirt or Grupo Frontera hat before the show. The Phoenix Mercury host the New York Liberty at Mortgage Matchup Center on Saturday, August 1, and the Arizona Diamondbacks face the San Diego Padres at Chase Field on Monday, August 3 — both indoor venues, so game-day heat isn’t a factor, but pick up Official team gear on Fanatics before you go. Theater fans can catch the touring Les Misérables at Phoenix Theatre’s Stephenson Theatre on Thursday, July 30.
With highs like these, cooking over a hot stove isn’t appealing — try a cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls blended up with a high-powered blender for a no-cook dinner. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door. If you’ve got fishing or hiking planned once it cools off, check out this $5 UPF 50+ sun hoodie deal for sun protection.
Next Few Days
Wednesday holds near Tuesday’s intensity at 110°F with another Extreme Heat Warning likely, then temperatures ease only slightly before high pressure rebuilds late week, bringing another stretch of Major to Extreme Heat Risk. Keep water, shade, and evening plans front of mind through it all.
