Chandler sits in the Sonoran Desert within the Phoenix metro area, where a warm, arid climate and a long growing season produce nearly year-round pollen exposure rather than a single sharp allergy season.
Tree pollen is the dominant springtime trigger, typically running from February through April, with mulberry, olive, ash, cottonwood, Arizona cypress, juniper, mesquite, and palo verde among the heaviest contributors; mesquite and palo verde often extend activity into early summer.
Grass pollen follows and frequently overlaps with late tree season, peaking from May through August, driven largely by Bermuda grass, along with rye, Johnson grass, and careless landscape varieties that can continue releasing pollen well into fall.
Weed pollen takes over from late summer through November, with ragweed, Russian thistle (tumbleweed), careless weed (pigweed), sagebrush, and saltbush producing some of the region's most aggressive symptoms. The overlap between lingering grasses and emerging weeds in late summer often intensifies reactions.
Non-pollen triggers are significant here as well: blowing desert dust, year-round outdoor molds in irrigated areas, urban ozone and vehicle pollution, and extreme dryness can all aggravate symptoms.
Overall, Chandler's allergy profile is defined by extended, overlapping pollen seasons compounded by persistent dust and dry-air irritants.
