Phoenix is in for a dangerous Saturday, June 13, with a high near 107°F and wall-to-wall sunshine — the National Weather Service has issued a widespread Moderate Heat Risk for the Valley, with isolated pockets of Major Heat Risk possible. If any outdoor plans are on your schedule today, get them done early or move them indoors entirely.
Today’s Setup
A dominant subtropical high is anchored over the region, pushing temperatures 3 to 8 degrees above normal for mid-June. Westerly winds stay light at 0 to 10 mph — no relief there. Overnight lows hold around 85°F, actually ticking up toward 87°F by dawn, which makes sleeping without AC genuinely uncomfortable. The Phoenix weather forecast is worth refreshing throughout the day.
Best Window To Be Outside
Your outdoor window is narrow. Trails at Camelback Mountain and South Mountain Park should be started and finished before 7 AM MST — after that, even desert-acclimated hikers will struggle fast. NWS forecasters note that brief gusty outflow winds are possible over the northern and eastern Maricopa County foothills during the late afternoon and evening, with a slim chance of an isolated storm reaching the Valley’s edges. It won’t cool things down meaningfully, but be aware if you’re out east of the metro.
Heat Safety Reminders
Isolated Major Heat Risk pockets mean heat illness can escalate quickly. Carry more water than you think you need, keep close eyes on children and elderly neighbors, and never leave pets in parked vehicles. Check on anyone in your neighborhood who may not have reliable air conditioning — this is exactly the kind of day that gets dangerous quietly.
Tonight: Ed Sheeran at State Farm Stadium
Ed Sheeran performs at State Farm Stadium tonight (June 13), which means hours of outdoor exposure at peak heat. Arrive as late as practically possible, wear your lightest clothing, and pre-hydrate before you leave the house. Grab seats through Get tickets on SeatGeek or Find tickets on StubHub. The Phoenix Mercury host the Los Angeles Sparks at Mortgage Matchup Center and the LCS Spring Finals run at Mullett Arena today — both indoor, air-conditioned venues and far gentler options if you’re flexible.
This Weekend & Next
Sunday, June 14, actually runs one degree hotter — near 108°F. The Louis Tomlinson How Did We Get Here? World Tour comes to Mortgage Matchup Center that evening; it’s indoors, so heat isn’t a factor — grab a Louis Tomlinson t-shirt before the show. The Arizona Diamondbacks open a series against the Los Angeles Angels at Chase Field on June 15 and June 16. A classic Arizona Diamondbacks jersey or Arizona Diamondbacks fitted cap is the move for the stands — and check out the outdoor gear deals if you need anything else for the trip.
Tonight’s Dinner
Skip the outdoor grill entirely — standing over open flame in 107°F heat is punishment. Load a programmable slow cooker this morning with chili or beef stew and let it work all day while you stay cool indoors. An enameled cast iron Dutch oven is also perfect once evening rolls around and you want a quick stovetop soup. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
The heat dome holds. Sunday climbs to near 108°F, and the NWS expects continued Moderate Heat Risk — with isolated Major pockets — through at least the middle of next week. Meaningful rain chances stay locked over northern and southeastern Arizona through this period. Stay hydrated and keep the AC running, Phoenix — this is a serious stretch.
