Phoenix rolled into Tuesday already baking, with mostly clear skies and temperatures stuck in the upper 80s to near 90°F before many people had finished their morning coffee. The heat is set to climb fast through the day, with a forecast high close to 110°F and very little cooldown after dark. That combination of scorching afternoons and warm, sticky nights will keep heat risk elevated for anyone spending time outdoors this week.
What To Expect Today
Most of the Valley will stay mostly sunny and dry, with a high near 110°F and light south to southwest breezes around 0–10 mph this afternoon. Isolated showers or brief thunderstorms could pop up over higher terrain and far western parts of the region, but the metro area is expected to remain largely dry. For detailed updates and hourly timing, check the latest from the NWS Phoenix.
Nighttime Relief Will Be Limited
Overnight lows will only slip into the upper 70s to mid 80s in most neighborhoods, which means homes without reliable air conditioning will not cool off much. If you need a break from the heat, the City of Phoenix is operating an expanded Heat Relief Network, including a 24/7 respite center downtown at 20 W Jackson St. and the Justa Center at 1001 W Jefferson St. Transportation assistance is available by calling 2-1-1 or checking local heat relief resources, according to the City of Phoenix.
Afternoon Winds Pick Up
Breezy conditions will become more noticeable Wednesday afternoon, with southwest winds around 5–10 mph and gusts up to about 25 mph in some valleys and higher terrain. Those gusts can kick up dust and reduce visibility. The combination of drier air and increasing winds will also raise localized fire weather concerns for some ridges and deserts. If you have evening plans and want the latest timing or wind updates, keep an eye on the forecast from NWS Phoenix.
Heat Safety
Limit strenuous activity during the hottest part of the day, stay hydrated, and check on elderly neighbors, young children, and pets. If your home does not have reliable cooling, consider visiting a cooling site or calling 2-1-1 for transportation help to a Heat Relief Network location. Try to keep outdoor plans flexible and shift activities to the morning hours or to shaded, air conditioned spaces whenever possible.
