Phoenix, Arizona – This summer’s monsoon has left Arizona parched, with rainfall and lightning activity across the state well below normal through July 25. Persistent southwest flow has kept deep tropical moisture from reaching the region, leaving much of Arizona—especially the Phoenix metro—dry as July draws to a close.
According to the National Weather Service in Phoenix, 2025’s monsoon storm activity is among the most limited in decades. Most of the state’s measurable rain fell during an isolated event on July 2, particularly along the I-10 corridor west of Phoenix. Since then, both rainfall totals and lightning strikes have remained near record lows. Only a few isolated spots have reported above-normal precipitation, while the majority of Arizona continues to lag far behind average monsoon moisture.
Communities in Maricopa, Pima, and Yuma counties are seeing especially dry conditions, raising fire weather concerns and increasing pressure on water supplies. Travelers along major roadways like I-17 and I-10 should remain alert for sudden dust storms, as parched soils increase blowing dust risk. Residents are urged to limit outdoor burning and to keep an eye on local fire restrictions.
The National Weather Service warns that, unless patterns shift soon, Arizona may close out July with one of its driest monsoon starts in recent history. Updates on monsoon conditions and potential weather pattern changes will be issued as needed.
