Phoenix is about to crank up the thermostat, with sunny skies sending temperatures into the upper 80s and low 90s from Thursday through the weekend. Today’s high is expected to land near 89°F, with even hotter readings likely Friday and Saturday. The warm stretch will feel more like early spring than late winter as light winds and very dry air let the sun heat the Valley fast. Forecasters say several daily records and unusually mild overnight lows could be tied or broken through the weekend. If you have outdoor plans, try to move workouts and chores to the morning or evening and keep water close.
What To Expect
The hottest part of the day will hit roughly between 2 p.m. and 5 p.m. The forecast calls for highs near 89°F Thursday, around 92°F Friday and about 94°F Saturday before readings slip back next week, according to the National Weather Service. Winds should stay on the light side, generally under 5 to 10 mph, so the heat will come mainly from strong sunshine rather than gusty breezes. Humidity will dip into the teens in many lower-elevation neighborhoods, which means the afternoon air will feel very dry and will dehydrate you quickly.
Heat Relief And Safety
The city operates a network of cooling centers, hydration stations and a dedicated downtown respite site that anyone can use for relief. You can check locations and hours before you go at the City of Phoenix Heat Relief Network. Some public libraries and recreation centers also extend evening hours during hot spells, giving you more options for an air-conditioned break. If you or someone you care for depends on air conditioning, plan ahead: pre-cool your home if you can, and check on neighbors, pets and outdoor workers during peak heat.
Impacts & Fire Weather
Dry afternoons will drive minimum relative humidity into the teens and create pockets of poor overnight recovery, which can boost small-scale fire risk for yard debris and prescribed burns, according to the National Weather Service. There are no watches or warnings in place right now, but forecasters say conditions favor very warm nights and an elevated fire-weather concern across parts of the lower desert. Bring water, wear sun protection and skip strenuous outdoor work during the peak-heat window.
Records could be set as early as Friday and Saturday, and Hoodline will update this page if watches or advisories are issued. For the latest forecast and local relief options, keep an eye on the National Weather Service and the City of Phoenix Heat Relief Network.
