Phoenix is already baking under clear skies on Tuesday, June 9, 2026, with temperatures climbing into the low 80s by midmorning and headed for the low 100s this afternoon. Overnight lows will only dip to the mid-70s, offering limited relief before the next day heats up again. Higher-elevation areas will be windier and drier, which keeps fire danger elevated across parts of the region. If you have outdoor plans, it is smarter to shift activity to the morning or evening and carry plenty of water.
Afternoon Heat And Winds
Afternoon highs are expected to reach about 104°F on Tuesday, June 9, then warm into the mid to upper 100s on Wednesday, June 10, as high pressure builds over the region, according to the National Weather Service. Breezy conditions will be strongest over the Arizona higher terrain, where gusts up to around 25 mph are possible and relative humidity may fall into the single digits, a combination that sustains an elevated fire danger. If you are working outside, take regular breaks and keep an eye out for local fire advisories.
Weekend Outlook
Temperatures are forecast to keep rising through the end of the week, with potential highs near 110°F on Saturday, June 13, and Sunday, June 14. Late-week southerly flow will bring added moisture beginning Friday, June 12, which could produce isolated thunderstorms over higher terrain while the valley floor stays mostly dry. The extra humidity will slightly limit nighttime cooling but will not erase the daytime heat, so treat weekend plans like peak-summer conditions.
Where To Find Relief
The City of Phoenix has opened its Heat Relief Network, including a 24/7 downtown respite center at 20 W. Jackson St., and a roster of cooling and hydration sites around the Valley; call 2-1-1 for transportation to a nearby location, according to the City of Phoenix. If you lose power or just need a cool place for a few hours, you can head to libraries or community centers and check the city’s list for hours and addresses. And as a reminder, never leave children or pets in parked cars and avoid strenuous activity during the afternoon peak.
