Summer is wasting no time cranking up the thermostat in Phoenix. This Saturday, June 20, brings plenty of sun and dry air, with daytime highs around 104°F and overnight lows hanging in the upper 70s. Clear skies and light winds will keep the weekend relatively tame by desert standards, a brief warm-up jog before the real heat run begins next week.
Hotter Midweek: 110s Return
A strong ridge will build northward over the region next week, and that is when the numbers really start to climb. High temperatures are expected to hit about 108°F on Monday, 109°F on Tuesday, and then surge into the low 110s on Wednesday and Thursday, topping out near 112–113°F, according to the National Weather Service.
Afternoon Gusts And Fire Weather
While winds stay on the lighter side through the weekend, afternoons will get breezier by midweek, with gusts potentially reaching 20–25 mph. Combine that with very dry air pushing minimum relative humidity into the single digits, and you get elevated fire-weather concerns. Poor overnight humidity recovery will not help either, so be extra careful with open flames and any spark-producing equipment during those hot, windy afternoons.
Where To Cool Off
Phoenix has its heat-relief network up and running, with cooling centers, hydration stations and a 24/7 respite site open across the city. Anyone who needs help getting to a site can call 2‑1‑1 for transportation assistance. For a full list of locations and hours, check the City of Phoenix page.
Tips For The Week
With temperatures pushing into the dangerous-heat range by late week, it is smart to plan ahead. Skip strenuous outdoor activity from mid‑morning through early evening, drink plenty of water, and check in on older neighbors. Keep pets shaded and well hydrated. If you have to be outside, aim for early morning or after sunset and keep an eye on updated forecasts as the triple-digit heat ramps up.
