Sunday, March 1, 2026: Phoenix woke to clear skies and mild morning temperatures in the mid 60s, and forecasters expect a sunny, unseasonably warm day with a high near 93°F. There is essentially no measurable rain in the forecast through the week, and overnight lows will stay unusually mild in the upper 50s to low 60s.
What To Expect
Today will be mostly sunny with light south southeast winds around 0 to 5 mph and highs near 93°F. Monday, March 2, should stay very warm near 91°F before a modest cooldown to the mid 80s on Tuesday, March 3. The National Weather Service in Phoenix puts the odds around 70% that the city meets or tops the daily high record of 90°F on Monday. Humidity is expected to fall into the teens during the afternoon, which means very dry air paired with the heat. According to the National Weather Service Phoenix, dry and sunny conditions are likely through at least Friday.
Heat Relief And Safety
City officials say heat relief resources are already in place for anyone who needs air conditioning or water, including extended cooling center hours and a downtown 24/7 respite site. The City of Phoenix heat plan includes a 24/7 respite center at 20 W. Jackson Street and expanded library cooling hours, with specific times and locations listed locally. If you do not have reliable cooling, try to schedule errands for morning or evening and bring water even for short trips into the sun.
Fire Weather And Outdoor Work
Afternoon humidity is expected to dip into the 10 to 15% range while overnight recoveries hover around 30 to 50%, a pattern that works for prescribed burns but increases the risk for yard debris fires if sparks are generated. Afternoon gusts up to about 20 to 25 mph are possible Monday and again late in the week, so forecasters advise delaying any open burning or spark producing projects until conditions improve. There are no active watches or warnings for the metro area at this time.
Bottom line: enjoy the sun, but shift strenuous outdoor plans to early morning or after sunset, carry water, and check cooling center hours if you need relief. If you plan to burn debris or use spark producing equipment, contact local fire officials or hold off until humidity rebounds.
