PHOENIX, Ariz. – Fall perfection has arrived in the Valley of the Sun. After a long stretch of summer heat, Phoenix is settling into a week of clear skies, calm winds, and comfortably warm afternoons — ideal for outdoor work, hiking, and evening activities across Maricopa County.
According to the National Weather Service in Phoenix, a stable high-pressure ridge will dominate the Southwest through the weekend. Daytime highs will range from 77°F to 82°F, while nighttime lows dip into the upper 50s to lower 60s under mostly clear skies. Light winds from the east and southwest will keep air quality stable and visibility excellent across the I-10 and Loop 101 corridors.
Forecasters expect this tranquil pattern to hold at least through early next week. No rain is in sight, and humidity levels will stay low — perfect for seasonal events, patio dining, and fall tourism across metro Phoenix. Residents heading out before sunrise may notice mild morning chills, a sure sign the desert is sliding deeper into autumn.
Outdoor recreation remains highly favorable, though hydration and sunscreen are still recommended during the warmest afternoon hours. With peak temperatures well below triple digits, the week ahead offers some of the most comfortable desert weather since early spring.
