About pollen in Murrieta

Weed pollen is the main story in Murrieta today, though it remains fairly mild overall. Tree pollen is essentially absent, and grass is barely registering. For most people, today's air should feel manageable, with only those especially sensitive to weeds likely to notice any effect. Looking ahead, grass pollen is expected to hold steady at a very low level through the next several days, so it shouldn't cause much concern. Weed pollen, on the other hand, is projected to creep upward slightly by the end of the period, which fits the season — late September is prime time for weeds like ragweed to become more active as summer gives way to fall. Tree pollen is likely to stay quiet for now, with species such as oak, sycamore, and mulberry not expected to become noticeable again until closer to spring.
