Arizona Pollen Counts Vary by Elevation
Arizona is not one allergy climate. In the low desert around Phoenix, Scottsdale, Mesa, Tucson and Yuma, pollen season starts early — mesquite, olive, ash and mulberry can be airborne by February, and Bermuda grass keeps counts elevated deep into summer. Above 4,000 feet in Flagstaff, Prescott, Payson and Sedona, the season starts weeks later but hits hard with ponderosa pine, juniper and oak. That is why a statewide pollen count alone rarely matches how you actually feel; use the city report closest to where you live and work.
