Tempe's allergy season is relatively mild compared to other US regions, running from April through September. However, the dry air and altitude around Tempe, AZ create unique challenges — pollen travels further and dry conditions can irritate airways.
Right now: March may bring early juniper pollen near Tempe depending on elevation and snowmelt timing.
Spring
Apr – Jun
Juniper, pine, and cottonwood tree pollen peak at lower elevations.
Summer
Jun – Aug
Grass pollen peaks. Higher elevations see delayed and shorter seasons.
Fall
Aug – Sep
Sagebrush and ragweed in lower elevations. Season ends earlier at altitude.
Dry air near Tempe can carry pollen over longer distances, but lower humidity means less mold than in humid regions. Elevation significantly affects local pollen timing — even a 30-minute drive changes conditions. PollenTracker accounts for these variations.
