Phoenix is staring down a high near 108°F today, Monday, June 15, as Monsoon Season officially kicks off in the Valley — get outdoor tasks done before 9 AM MST or plan to stay inside until the evening hours.
Today’s Setup
Today marks the official start of Monsoon Season, and the atmosphere is already playing along. The National Weather Service reports moisture levels running 150–200% of normal for mid-June — enough to fuel isolated storms. A slight chance of rain showers lingers before 8 AM MST, then a slight chance of showers and thunderstorms is possible through the afternoon and evening, especially over the Superstitions, White Tank Mountains, and foothill terrain east of the city. Lower-desert storms aren’t ruled out either. Between those chances, expect sunny skies and west-southwest winds at 5 to 10 mph.
Best Window To Be Outside
Your comfortable outdoor window is narrow: before 9 AM or after sunset. Camelback Mountain and South Mountain trailheads will be punishing by mid-morning. Whenever you’re out, an insulated tumbler 30oz packed with ice water is non-negotiable, and moisture wicking undershirts men will make the heat far more bearable through the day.
Heat and Storm Risk
The National Weather Service is calling for Moderate Heat Risk across the Phoenix metro, with isolated pockets of Major Heat Risk possible. Temperatures are running 3 to 8 degrees above daily normals. Tonight, a slight chance of storms continues before 9 PM MST, then skies clear — but lows only drop to around 84°F, with temperatures actually climbing to near 87°F overnight. Keep the AC running all night. If afternoon storms do pop, brief outages are possible; the DARAN 288Wh Power Station at $90 is a well-timed deal for Prime members heading into monsoon season.
D-backs Host the Angels at Chase Field Tonight
The Arizona Diamondbacks host the Los Angeles Angels tonight at Chase Field, with the series continuing Tuesday and Wednesday as well. It’s a great excuse to get out and cheer on the home team. Gear up with an Arizona Diamondbacks jersey and an Arizona Diamondbacks fitted cap, and Get tickets on SeatGeek. Slip on a pair of men’s sport sandals for the walk to and from the ballpark.
Dinner Tonight: Skip the Stove
At 108°F, firing up the range is a hard no. Cold Thai noodle salad, a build-your-own wrap bar, or smoothie bowls are all fast, refreshing, and zero-heat options. A high-powered blender makes those smoothie bowls effortless. Need supplies? You can order groceries on Amazon and have everything delivered in time for dinner.
Next Few Days
Tuesday climbs to 109°F under clear skies with no storm chances — hotter but straightforward. Relief is on the way: the National Weather Service says an eastern Pacific area of low pressure will help cool and dry the region during the back half of the week and into the weekend. Wednesday, June 17 brings solid evening options: the Phoenix Mercury host the Las Vegas Aces at Mortgage Matchup Center, and the ALL THE FEELINGS TOUR with METRIC, BROKEN SOCIAL SCENE, AND STARS plays Arizona Financial Theatre — Find tickets on StubHub for either. Looking ahead to June 21, the Khalid: It’s Always Summer Somewhere Tour lands at Arizona Financial Theatre — grab a Khalid t-shirt and make a night of it. Stay updated with the Phoenix weather forecast as the monsoon pattern evolves this week.
