About pollen in Glendale
Weed pollen is the main driver of today's high overall count in Glendale, with grass close behind at a moderate level that sensitive individuals will likely notice. Tree pollen is quiet, so any symptoms are almost certainly coming from weeds and, to a lesser extent, grasses in the air. Looking ahead, weed pollen is expected to stay high and edge even higher by the end of the forecast period, while grass holds steady before ticking up slightly as well. Tree pollen should remain absent through the coming days, which fits the season — local trees such as mesquite, olive, and ash typically shed pollen in spring, not fall. This time of year in the Valley is really ragweed and related weed season, so anyone sensitive to weeds should expect conditions to stay uncomfortable, with grass adding a secondary layer of irritation.
