Flagstaff, Arizona – Arizona residents will wake up to sun and summer heat on Saturday, July 26th, as Flagstaff prepares for highs near 80°F and gusty southwest winds. Anyone with outdoor plans or travel along I-40 should expect breezy conditions that could kick up dust and reduce visibility, especially during the afternoon hours.
According to the National Weather Service, winds in Flagstaff will shift southwest by late morning, reaching 11 to 16 mph, with gusts possibly hitting 26 mph. Hikers, cyclists, and road trippers should secure loose gear and stay alert for rapidly changing wind speeds along exposed roadways like I-40 and U.S. 180. Staying hydrated and avoiding peak afternoon sun are smart moves for anyone outdoors.
Sunny skies and dry air dominate Saturday’s forecast, setting up a classic high-elevation Arizona summer weekend. By Saturday night, winds will settle and skies will remain mostly clear, with lows dipping to the upper 40s—perfect for evening stargazing or camping just outside city limits.
Sunday continues the warm, dry trend, with highs jumping to 84°F and gusty breezes persisting through the afternoon. The summer heat lingers into Monday before a weather shift brings a 30% chance of thunderstorms by Monday night and a bump in overnight humidity. Storm chances climb to 40% on Tuesday, which could bring isolated showers and brief cooling relief.
Travelers and locals should keep an eye on rapidly changing conditions early next week as monsoon moisture returns. Make sure outdoor plans include backup options and keep emergency alerts enabled.
More updates and possible advisories are expected if storm activity increases after Monday night.
