Low Pollen in Simi Valley, CA

About pollen in Simi Valley

Weed pollen is the most active influence on Simi Valley's air today, though it remains in the low range and should go unnoticed by most people. Grass pollen is present as well, but only in trace amounts. Tree pollen is quiet, so overall this is an easy day for anyone who deals with seasonal allergies. Looking ahead, this pattern is expected to hold steady through the next several days, with weed pollen staying at a low level and grass continuing to linger in the background at minimal amounts. Tree pollen should remain absent for now, consistent with the time of year, since local trees such as oak, sycamore, and olive typically release their pollen in spring rather than fall. The current mild conditions fit the seasonal norm, as weeds like ragweed are the main source of allergy activity in late September.
