Mostly clear skies and about 79°F at Phoenix Sky Harbor kick off Thursday, July 2, 2026, but the valley is on track to jump into the low 100s by this afternoon. Winds will stay light, and overnight temperatures are only expected to fall into the mid-70s, so there will be little real relief after sunset. If you have outdoor plans, aim for the early morning or late evening and keep water close at hand.
Today's Forecast And The Week Ahead
Highs are expected to climb to around 102°F on Thursday, July 2, 2026, push into the mid-100s on Friday and top out near 107°F on Saturday, July 4, 2026. Sunday is set to stay very hot near 108°F. Forecast guidance points to an even sharper jump early next week, with widespread highs of 110–112°F possible Monday through Wednesday and overnight lows rising into the 80s in parts of the Valley. All of this comes from the National Weather Service in Phoenix, which is tracking the heat as it builds.
Fire Restrictions And Holiday Safety
The city has put Stage 1 Fire Restrictions in place and is specifically prohibiting consumer fireworks within one mile of mountain preserves, regional parks and other sensitive public lands. With very dry fuels and those familiar afternoon breezes, fireworks and open flames add unnecessary risk near desert areas and trails. For the latest on restrictions and the city's heat-response actions, check the City of Phoenix.
Cooling Options And Practical Tips
Phoenix is part of the regional Heat Relief Network, which includes cooling centers, hydration stations and overnight respite sites. If you need a cool place or help getting there, call 2-1-1 for locations and transportation options. Hydrate often, steer clear of strenuous activity during midday highs, and check in on neighbors, pets and anyone without reliable air conditioning. Nights are expected to feel more oppressive as humidity creeps up next week, so plan evening activities with extra caution and do not count on the dark to cool things off much.
