Local Environmental Conditions
The center of Avondale, Arizona sits in a varied landscape of scrubland, bare ground and farmland. With the Salt River nearby, riverside trees such as willow and poplar along its banks contribute to the local mix. Allergenic trees nearby include poplar and willow. Grass pollen is significant here, and pigweed and ragweed contribute weed pollen.
Poplar and willow lead the season in late winter, as temperatures climb to around 15°C, and tree pollen reaches its peak. Then come the grasses, strongest in mid-spring and fading by mid-fall. The season closes with pigweed and ragweed from early summer into early fall. In this dry climate, pollen can linger in the air for long spells without rain.
