About pollen in Downey
Pollen levels in Downey are quiet today. Tree pollen is absent, while grass and weed pollen are both present but at very low levels, unlikely to cause much trouble even for those who are sensitive. Overall, this is an easy day for most allergy sufferers. Looking ahead, expect little change through the next several days. Grass should hold steady at a low level, while weed pollen may tick up slightly, moving from very low toward a more moderate presence as the week goes on. This lines up with the season, since tree pollen from local species like oak and sycamore has long since wound down after its spring peak, and grass pollen typically stays subdued outside its late spring and early summer high point. The gradual rise in weed pollen is typical for early fall, as ragweed and related plants become more active through the season.
