About pollen in San Marcos

This is typically a calmer stretch in the pollen calendar, falling between the end of the weed and grass season and the start of winter tree bloom, so most people should find the air fairly easy to tolerate right now. Looking ahead, conditions are likely to remain mild over the next few days, with no major shifts expected this time of year. Southern California's tree season, driven by species like oak, sycamore, and alder, typically doesn't ramp up until late winter into spring, while grass pollen follows in late spring and early summer, and weeds such as ragweed peak in late summer through fall.
