TUCSON, Ariz. – Southern Arizona is in for a postcard-perfect fall weekend, with bright blue skies, light winds, and temperatures edging back into the 90s. After a mild Friday, the desert warmth returns full force for Sunday, bringing ideal weather for hiking, fall festivals, and road trips along I-10.
The National Weather Service in Tucson calls for a steady warming trend through the weekend. Friday starts with calm winds and a high near 80°F. By Saturday, expect 84°F with sunshine from sunrise to sunset. Sunday will feel more like early fall than mid-October, reaching 90°F with low humidity and clear skies — classic desert perfection.
Local residents planning to visit Mount Lemmon or Sabino Canyon can look forward to cool morning air in the 50s and calm afternoons. Those hitting the trails or hosting outdoor events should still pack sunscreen and water. Even in October, UV levels remain high across southern Arizona’s valleys and foothills.
Travelers along I-10 from Tucson to Phoenix will enjoy excellent driving conditions, with light breezes and no precipitation expected. The pattern stays dry into next week, with Monday bringing another warm, sunny day near 90°F before a gradual cool-down midweek.
This stretch of weather marks one of the most stable periods of the fall season — perfect for decorating, exploring desert parks, or planning a weekend barbecue before cooler air returns later next week.
