Phoenix is baking today, Thursday, August 6, with sunny skies and a high near 108°F that will feel like 112°F once you factor in the heat index. If you’ve got yard work, a hike, or errands on the list, knock them out before 9 a.m. — anything outdoors during the afternoon is genuinely dangerous heat.

Today’s Setup

Overnight lows only eased into the upper 80s (around 87°F, actually creeping back up toward 89°F before sunrise), and today’s high climbs to 108°F under mostly sunny skies with west-northwest wind around 0 to 10 mph. Rain chances sit at just 3%. The National Weather Service’s Phoenix office notes the atmosphere is heavily capped today, so even with monsoon moisture around, the valley isn’t likely to tap into it for storms.

Best Window To Be Outside

Your only real window is early morning, roughly sunrise to 8 or 9 a.m., before temperatures ramp up. A sunrise loop at Camelback Mountain or South Mountain Park beats the heat and the crowds. Evenings don’t offer much relief tonight since lows only fall back into the upper 80s.

Heat, Dust, And Storm Chances

Per the Area Forecast Discussion, shower and storm chances this week favor the high terrain and southeastern Arizona, not the Phoenix metro. For south-central Arizona, the bigger risk is gusty outflow winds and blowing dust — haboob conditions — rather than rain, if any storms manage to collapse nearby. Friday looks similar: sunny, 111°F, heat index near 113. Storm chances for the lower deserts don’t really pick up until late this weekend into next week.

What To Bring

SPF 50 sunscreen and a Yeti hopper soft cooler stocked with ice water are non-negotiable if you’re out midday. It’s also worth grabbing the UPF 50+ sun hoodie deal for anyone spending time outside this week. Keep sunglasses handy too — blowing dust from outflow gusts can show up with little warning.

Local Games And Events

The Arizona Diamondbacks host the Los Angeles Dodgers Friday, August 7 at Chase Field — with the roof and AC running, it’s your best escape from that 111°F heat. Get tickets on SeatGeek and grab Official team gear on Fanatics before first pitch. Music fans should also mark down Lionel Richie and Earth, Wind & Fire at Mortgage Matchup Center on August 11 — pick up a Lionel Richie t-shirt ahead of the show.

Tonight’s Meal

With the heat keeping you indoors, lean into comfort food: a batch of slow cooker chili or beef stew is easy to start in the morning and ready by dinner. A programmable slow cooker or an enameled cast iron Dutch oven both work great here. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.

Next Few Days

Extreme heat sticks around through the weekend, with Friday’s 111°F running a few degrees above Thursday. Humidity stays higher than normal, so the heat index will keep outpacing the actual temperature. Storm and rain chances for the Phoenix area don’t really build until late this weekend and into next week, per the National Weather Service.
