Gilbert, Arizona, sits in the eastern Phoenix metro within the Sonoran Desert, where a warm, arid climate and a long growing season produce an allergy profile that is active nearly year-round rather than confined to a single peak season.
Tree pollen is the most intense trigger, typically beginning in February and running through April, driven by mulberry, olive, ash, mesquite, palo verde, juniper, and cottonwood—many of them non-native landscape trees that thrive in irrigated suburban yards.
As temperatures climb, grass pollen takes over from late April through summer and often lingers into early fall, with Bermuda grass as the dominant offender alongside ryegrass overseeded on lawns in cooler months.
Weed season intensifies in late summer and fall, featuring ragweed, careless weed (pigweed), Russian thistle (tumbleweed), and sagebrush, generally peaking from August through October. Overlap between lingering grasses and emerging weeds in late summer can noticeably worsen symptoms.
Non-pollen allergens are also significant: blowing desert dust, particulate pollution from regional haze, and outdoor molds stirred up by monsoon moisture and irrigation all contribute year-round irritation.
Overall, Gilbert's allergy profile is defined by an early and heavy tree season, persistent grass exposure, and dust-driven irritation layered on top of traditional pollen cycles.
